The best way to verify you are buying the best bike for you is to test ride a lot.

Buying a new bike? Test ride tips to make the most of your time

by John Brown,

The best way to find the right bike for you is to do some research on models you like. Then verify their size to your body and test riding your choices a lot. How do you make the best use of your time while test riding these bikes with so many choices? Read on for a complete list of how to test ride efficiently.

Test ride bike plan research

Any good test ride begins with research. First, review what type of bicycle you would like, then check out the websites of some popular brands. Please pay close attention to the prices of each bike and what it buys you. A few things to look for are the number of gears, what type of suspension it has, tire size, frame material, and brake type. Once you have gotten a general sense of what is available, you can plan a trip to the bike shop.

Pick a shop

Give a call to the shops closest to you and verify they have the models you want to test ride.

Before looking further, call a shop closest to you and verify they have the models you want to test ride.

Once you have researched a few bikes you like, give some local dealers a call. Most brand’s websites have a dealer locator to help you find the closest shop. Give a call to the shops closest to you and verify they have the models you want to ride. Because shops can’t stock every possible model in every possible size, call to ensure they have the right model in a size that is close to what you are looking for.

Make a date to test ride.

Check the weather and your schedule, then pick a good time to head into the shop. Keep in mind that shops and roads are less busy during the workweek. Therefore, Monday thru Friday is the ideal time to test ride bikes. If you need to go in on the weekend, call the shop and see when they are least busy and make an appointment if possible.

Dress appropriately

It makes no sense to test ride bicycles if you are not dressed for the occasion. Wear your Jersey, Shorts, bring your helmet, and bring shoes and pedals if you ride clipless. Another helpful thing is to bring your existing bicycle with you. They can replicate the setup of your current bike to new bikes you would like to test ride.

Bring your ID

When test riding bikes, you are potentially borrowing thousands of dollars from the shop. Therefore, it’s expected for shops to ask for some form of collateral. At the minimum, bring your ID and a major credit card.

The test ride

Test rides don’t need to take hours, but a three-minute spin is rarely enough time to make a real impression. Expect to take at least 15 minutes on each bike, with more time spent on the first few bikes you ride. When riding, try to focus on how the bike accelerates, how easily it changes direction, and how stable it feels. A great way to do this is to pick a set route with some flat area, some climbs, and at least one good descent. Riding the same course with different bikes makes comparing them easier.

Narrow it down to bikes

Once you get a feel for a few bikes, you can start narrowing down your choices. I find it best to pick two and then ride them back to back, concentrating on fit and comfort rather than speed and stability. Have the shop begin dialing in your fit on these two bicycles to see which one really is the best for you. Once you have a bike that rides well and fits well, you are ready to buy.

Buy everything you will need

A bike that rides great is the key ingredient in a great bike ride, but it’s not everything. Remember that your new bike needs things like a water bottle cage, kickstand, lights, and maybe clipless pedals or a better fitting saddle. Consider all the situations you may run into on your new bike and buy the products you need to be prepared.

Hopefully, your next bike purchase will be fun and informative.

We now have: 24”, 26”, 27.5”, 29”, 27+ and 29+ wheel sizes for mountain bikes. Take a look below to see the pros and cons of each size.

Mountain bike wheel sizes: past, present and future explained

by John Brown, 

Here is a brief history and a look into the future of mountain bike wheel sizes. Once the 29er revolution took over, many companies started looking at even more sizes. Therefore, we now have: 24”, 26”, 27.5”, 29”, 27+ and 29+ wheel options, with another new dimension on the horizon.

The Mountain Bike began it’s commercial success in 1978 in the mountains around the San Francisco bay area. A group of friends started racing down mountain roads on trash-picked Schwinn Excelsior cruiser bikes. Quickly, riders demanded a more durable bicycle that could not only bomb down the hills, but turn around and ride back up. To that end, Joe Breeze of Breezer bikes was happy to oblige by building the first ever Mountain Bike. Considering there were only 26” balloon tires (like the ones on the Excelsior) That is what he used for the first Mountain Bike, setting the tone for all Mountain Bikes built over the next 25 years.

Early changes to wheel sizes

By the early 90’s, mountain bikes had exploded. There were professional mountain biking events all over the world, a prime-time TV show (Pacific Blue anyone?) and mountain bikes in every garage in the country. On the wave of MTB excitement bicycle brands started investing serious money into new technology development, and one of the areas of interest was wheel size. Starting things off was Cannondale with their long heralded “Beast of the East” that used a 24” rear wheel. The benefit of a smaller wheel is better acceleration and the ability to make shorter chainstays.

Cannondale “Beast of The East” with 24″ rear wheel

On the other side of the country, in Petaluma California, a different idea was being hatched. Based on the development of the 700x48c “Rock and Road” tire by Bruce Gordon, A custom builder caller Willits, started making mountain bikes with 700c wheels. The owner of Willits, Wes Williams, was well connected within the cycling industry and became the advocate for what would be called a 29er. From Wes’ influence, Trek, the largest bike brand in the world, launched production 29ers through their Gary Fisher brand. At that point 29ers were in the main stream and now with so many wheel sizes take a look below to see the pros and cons of each size.

Rock and Road tire that was the start of the 29er movement

It all started with a 26” wheel size

The 26 inch wheels have existed for over 100 years. Furthermore, the critical dimensions of these wheels haven’t changed. Therefore, you could theoretically fit a tire from 1930 onto a rim of today. In an industry that releases new products every year, that consistency is amazing. Currently, 26” wheels are used primarily on department store Mountain Bikes or cruiser bicycles. Therefore, 26″ replacement parts can be found easily and inexpensively.

27.5” and 29” wheels

While 29ers led the way for new wheel sizes, 27.5” wheels were also popular in the initial wheel size change. The reason 29ers took hold so quickly was, in comparison to 26” wheels, they roll over objects easier and have better traction. Conversely, the downside to larger wheels is more mass to push around. In fact, The issue with mass is why 27.5” wheels became popular. A 27.5” wheel has similar traction and roll over to a 29er with much less weight. Therefore they accelerate and change direction more easily. You will now find 29” and 27.5” wheels on almost any mountain bike sold in bike shops. Typically, you see 27.5” wheels on smaller size bikes and 29” on the larger sizes. Also, full suspension bikes use 29ers on the lower travel options and 27.5” on longer travel bikes.

Plus wheel sizes

Plus sized tires are a new development in the cycling industry. In detail, they use the same rim diameter as 29″ and 27.5” bikes, but the rims and tires are wider. For example, a standard tire width is around 2”, while plus tires are 3” wide. As a result,  plus sized tires puts a lot more rubber on the ground, and gives you amazing traction. With a plus sized tire, you can expect to climb up almost anything with ease. Therefore, once difficult trails become easier, and it feels as if every turn has a berm. The penalty for all that traction is additional weight. Additionally, having large tires increases the tire’s overall air volume and makes finding the right pressure a bit more complicated. If you are interested in plus tires, your bicycle has to be built to accept their additional size. Usually, it’s just best to buy a complete bike.

The future wheel sizes

The development of wheel sizes has slowed down a bit for the cycling industry. With that being said, the movement has shifted to tires. The most recent buzz is coming from the 29” x 2.5” size tire. This “Big 29” tire is looking to be the new size of the year. The reason that size is getting attention is because it blends the speed and agility of a standard 29” tire with the gravity defying traction of plus tires.

What wheel size is best for You

I would love to say it’s easy to measure the pros and cons of each wheel/tire size, cross reference that information with your personal preferences and decide what is the right thing for you. Sadly, that doesn’t work. In reality, the best way to see what is going to work for you is to test ride them. Test rides are the best way to match your riding style with one of the many options available today.

Mountain bike hacks: fat bike tips and tricks for winter fun!

by  John Brown. HaveFunBiking.com

For many of us, riding offroad through the winter is impossible without a fat bike. Our trails get covered with snow in December and don’t see the light of day again until April. While riding a fat bike is a great substitution for riding a mountain bike, it does behave differently than a standard mountain bike. Here are a few quick and easy hacks to riding fat bikes that will get you enjoying the snow in no time.

Why a fat bike

What makes a fat bike special is its ability to ride though deep snow with ease. The reason it is at home in snow is that these tires are between 4” to 5” wide. That width offers traction and flotation on the softest of terrains like snow and sandy ground cover.

Tire pressure

With wider tires comes a larger overall air volume, meaning that fat bikes have more space for air in their tires than a standard mountain bike. Due to that increased volume, fat bikes use a very different air pressure than your standard mountain bike tire. As an example, in very deep snow it’s not unheard of to run the tires as low as 8 psi. By contrast, a standard mountain bike tire at 8 psi would be completely un-rideable. Proper air pressure for a fat bike tire can be difficult to achieve if you don’t know what you are looking for. Basically, you want the tire to be able to deform easily over terrain, but not be so low that the tire “squirms” or collapses under hard turning efforts. I find it easy to get here by filling the tires until they are slightly less than firm, then lowering the air pressure incrementally over the first few minutes of a ride until the tires really perform well. You will know you let too much air out if the bike bobs up and down with each pedal stroke.

Turning

Due to the soft nature of snow, turning can be tricky. While turning on a normal mountain bike you move your body weight forward rely on the tires traction, then aggressively force the bike through the turn. Considering snow is soft and will not support that type of maneuver turning requires a slightly more finessed approach. First, leave your weight in a neutral position centered over the bicycle. Next, shift your weight toward the inside of the turn and begin turning the bars slightly toward the turn. The front wheel is more of a tiller than anything else.  Use it to direct the angle and direction of the bike, but resist the urge to load it up with weight. As the bike angles toward the turn, focus your weight on the rear wheel. If done properly, you will feel as if the bike is turning from the rear wheel rather than the front and your front tire won’t wash out.

Climbing with a fat tire bike

Climbing with limited traction can be difficult as well. Rather than putting your bike in its lowest gear and muscling up the hill you need to be wary of not letting the rear tire slip. If you drop the bike into its lowest gear, chances are the rear tire will have too much torque. Too much torque will cause your tire to rip through the snow and slip. The best thing to do is move your weight backward and pedal with as even a pressure and cadence as possible. Standing and pedaling, or jabbing on the pedals will most likely cause the rear wheel to break free.

Ice and studs on a fat tire bike

On snow covered trails that get ridden often it is possible for the trails to get packed in and begin to freeze solid. Once ice is on the trail it becomes very difficult to control the bike with standard rubber tires. For this reason, I recommend adding studs to your tires if your trail riding is susceptible to ice.

Overall fun

The biggest tip I can give to fat biking is to keep it fun! Riding a fat bike is a totally different experience than riding a normal Mountain bike, and requires its own skills. Try not to get frustrated because it handles differently than your other off road bikes, just focus on building some new skills. Also, with riding in colder temperatures, enjoy the time you have. While a 4 hour mountain bike ride in the summer is great, you may not be able to stay warm that long through the winter. Beyond the different skills and time, enjoy the unique rewards only Fatbiking can give you.

Tips and Tricks to Adjust Your Bike’s Rear Derailleur

by John Brown, HaveFunBiking.com

It goes by many names, the rear derailleur. It is also known as the “s,” the “hangdown,” or the mech. Here in the U.S. we refer to it as the rear derailleur. The device that moves your bike’s chain from gear to gear letting you traverse hills with ease. Even though derailleurs are sturdy and relatively maintenance free, they do require attention occasionally. Look below for the step by step instructions on how to adjust your bike’s rear derailleur.

 Rear Derailleur Terminology

Twist shifter – A shifting device that rotates around the handlebar like the throttle of a motorcycle.

Trigger shifter – A Shifter that activates by pushing or pulling a set of paddles with your thumb and index finger.

STI shifters – Technical this stands for Shimano Total Integration and speaks directly about one brands type of road bike shifter, but it has become the generic term for any drop bar shifter/brake lever combo.

Thumb shifter – A shifter that can be mounted in many places like; the stem, bar end, brake lever, or top of the bar. These shifters are the most rudimentary type of shifter, and operate by simply actuating a lever with your thumb.

Derailleur parts

(A) Jockey Wheels- two small wheels on the derailleur on which the chain run. They are mounted onto the derailleur cage

Limit screws- The limit screws control the area of motion a derailleur has. On most derailleurs there are three limit screws: the upper limit, Lower limit, and B-limit. The upper limit screw sets the maximum distance the derailleur can shift in high gears. The lower limit screw sets the maximum distance the derailleur can shift in the lower gears. The B-limit screw sets the distance the upper jockey wheel sits from the cogs.

(B) Barrell adjuster – This is an adjustment device on the back of most derailleurs. It is the area where the derailleur cable enters the derailleur and can increase or decrease the cable tension by threading it in and out.

(C) Pinch bolt – The pinch bolt is where the derailleur cable gest secured.

(F) Derailleur hanger – The portion of the bike frame where the rear derailleur is mounted.

Rear Derailleur

Not defined above is the Upper Knuckle (E), and lower knuckle (D)

Is everything straight?

The cogs your rear derailleur shifts across can have as little as 2.14 millemeters of spacing between them. Considering the spacing is so narrow, look to see that everything is aligned properly before you start adjusting your rear derailleur in vain. Look first at the derailleur itself from behind. You should be able to see if the derailleur itself is aligned properly. A tell-tale sign of damage is when the two Jockey wheels don’t line up with the cogs or each other (see picture).

Next assure that the derailleur hanger is aligned properly. This is easily seen when the derailleur appears straight, but not in line with the cogs. Consequently, if either the derailleur or derailleur hanger are bent, it’s best to take it into your local shop for a remedy.

Step 2, A man has got to know his limitations

Before attempting to adjust the derailleur properly, set its usable range. First, loosen the pinch bolt and let the derailleur run on the smallest cog. Next, pedal forward while visually and audibly inspecting how the chain runs on the smallest cog. The chain should run smoothly without any clicking, or skipping noises. If it runs smoothly, don’t worry about the upper limit. when you do experience skipping or noise, look closely at how the chain runs on the cog (looking from behind is easiest). If the chain isn’t coming directly off the upper jockey wheel and going straight onto the small cog you need to adjust the upper limit. By threading the limit in or out you can adjust where the derailleur sits in relation to that smallest cog (note: the limit screws don’t need to get “tightened” down, they simply act as a stop for the derailleur).

Once the upper limit is set, pedal forward and push on the derailleur lower knuckle until it moves the chain into the largest cog. If the chain has issue getting into the largest cog, or jumps over that cog into the wheel spokes, you need to adjust the lower limit screw in a similar fashion to the upper limit screw.

Rear Derailleur Tension

With the limits set, you can now move on to tightening the cable and trying to shift. Make sure the shifter is in its lowest gear by shifting down while gently pulling on the shift cable. With the shifter in its lowest position, ensure all housing ends are settled into the frame properly then pull the cable taught through the derailleur.  With the cable taught, tighten the derailleur pinch bolt onto the cable. Trim any excess cable so that only about one inch of cable extends beyond the pinch bolt and crimp it off as not to fray.

While pedaling, shift one gear up. Ideally, the chain will easily move from the smallest cog up to the next cog. It should stay on the second cog and run quietly and smoothly. If it hesitates to get to the second cog, increase cable tension by rotating the barrel adjuster out. If you cannot increase tension enough with 3 or 4 turns of the barrel adjuster, thread it back in, loosen the cable pinch bolt, pull the cable taught, and tighten the pinch bolt again. Once you have the chain shifting up the cogs easily, check to see if it will smoothly move back down the cog stack by shifting from the largest cog down and inspecting. The only difference is in the adjustment. If the chain hesitates to move down the gears, turn the barrel adjuster in (relieving cable tension).

Rear Derailleur Trouble shooting

What happens if you can get the chain to move up the cogset well, but can’t get it to move back down the cogset easily. In some cases, the cable and housing can be corroded and causing drag. This drag won’t affect the shifting moving up the gear set, but it will stop the derailleur from returning. In tis case, you can clean and lube the cables and housing, or just replace the cable and housing all together.

Additionally, there may be a grinding/banging noise in only the largest cog. That noise is caused by the upper jockey wheel running on the largest cog. To remedy this, tighten the b-limit screw until the noise subsides.

Finally, a common problem is if you get skipping while pedaling up steep grades or under load. If your derailleur is adjusted properly, and you’re getting skipping, it may be related to a worn out drivetrain. As your chain ages, it stretches slightly. As the chain stretches, the front face of the gears will wear in unison with the chain stretching. Once the chain stretches beyond the point where it will mesh with the gears, you will experience skipping under load.

Working on your own bike is fun. Also, your appreciation for the technology and engineering that goes into what is considered a simple machine will grow with each turn of the wrench. Periodically, you will run into a problem you cannot solve. If that is the case, bring your bike to your local shop, talk honestly with the mechanic about what you tried and what you are trying to accomplish. As a result, you will find that most mechanics will be happy to teach you what you need to know.
