For Your Consideration: Notes About Choosing a Bike

2008 Trail Ride Field
As winter begins to recede and the warm winds of spring breathe life into daffodils and our desire to return to routine outdoor activity, thoughts of a new bike may also emerge. Shopping for a bike can be an adventure of sorts; it is certainly a multi-layered process that is both labor-intensive and fun. To help you find your perfect bike, here are a few things for your consideration.

If you are new to cycling imagine where you will ride your bike and consider the surface. Pavement and cement are compatible with skinny tires, while packed or crushed gravel will require some knobby tread and a little bit of width to the tire. An experienced rider with solid bike handling skills can ride skinny tires on packed gravel, but a new rider would probably feel safe with fat tires.

Gearing is an important consideration for someone who lives in a hilly or mountainous area. To be able to climb uphill and maintain a high cadence so my legs don’t blow up, I have three chain rings on my road bike instead of the traditional two. I live in the Rocky Mountains and need a wide range of gears to support me on this kind of cycling terrain. My town bike/commuter is a 2007 Giant Cypress W with an internal 7-speed rear hub. Around town, seven gears are manageable. When I am cycling for fitness, be it on road or trail, my preference is to have and use all the gear choices that support a highly pleasurable experience!

The weight of the bike may also be a buying factor, particularly for those gals who are going to be spending a fair amount of time pedaling uphill. Consider the lightest bike you can afford, even if it means dipping all the way down to the lint in the bottom of your pocket! My road bike weighs 16 pounds and I do not carry an ounce of regret in my body in regards to how much it cost. Pedaling uphill for 20 miles affords me the opportunity to reflect on how happy I am that my bike is so light. Although I still have to work hard to turn the cranks I am always able to finish a mountain climb with a little something left in the legs.

Bike weight is also an issue for mountain bikers, but the need for well-designed full suspension trumps weight if you live in the mountains. The most tunable suspension spring system consists of air. Look for a bike that is equipped with a suspension fork and rear shock that is air-sprung. There are two drawbacks to air springs. The first is that as an air spring is compressed it requires exponentially more force to compress it further, making it nearly impossible for a small rider to access full travel. The second drawback impacts maintenance – the rubber gaskets and o-rings that seal the system are highly vulnerable to deterioration from friction and, as a result require more frequent maintenance intervals than coil springs. Despite these drawbacks I ride air springs front and rear because for me the weight and tenability outranks the need for maintenance. Plus, the Fox fork on my Cypher can be factory-tuned to perform better for my body weight.

When you test ride, take your time. Don’t think about price or color as much as you pay attention to how the bike feels. Saddles, seat posts, and grips can be changed easily, as can tires so none of these items should be considered deal breakers. Drive train components can be changed, too, but at a significantly higher cost. If the ride feels stiff or harsh new tires are not going to change that quality. The fit and feel of the frame itself is the most important consideration because everything is built upon it. Trust your intuition – if the bike feels right, it is right for you!

Avatar I am primarily a cx rider with a love for mtn biking - i went with a giant trinity alliance to mix them up on the road and do some miniature triathlons and it's a blast to ride - my question, don't laugh, is that unlike cyclocross and mtn biking weight doesn't seem to really play as big a factor in time trialing except for the wheels. Have I put in too much magazine time or should I try to shave every gram off my bike like the hardcore tri folks?
Avatar To get the most out of your Trinity, the best approach is to prioritize your spending in regarads to the things that will impact your performance. Begin with a professional fit by someone who is trained/certified in Tri-specific fit. The body position for TT and Tri is not the same as road racing. Contact your local tri-club to inquire about fitters who understand tri bikes and tri bodies.
Positioning the body low with extended arms and elbows tucked in under the shoulders is intended to improve aerodynamic efficiency. Because this posture can be challenging to maintain (and a trained fitter knows this) your body may have to be trained to adopt this posture through incremental adjustments over a period of time. The good news is, aerodynamics do not become critical until the bike speed reaches 24mph and stays there.
As you mentioned, wheel weight also has a significant impact on performance. If you have the money then invest in a light weight set of racing wheels. Save the stock wheels for your training rides and install the lighter set on race day.
Finally, the bike itself. If you are racing on a course with several significant climbs, then the overall weight of the bike does matter. Consider the courses before you begin shelling out mega bucks to lighten your Trinity.
Take care,

Avatar I've been riding my Giant Avail for my triathlons this season and I have been happy with the performance in the sprint tri, but during the Olympic distance tri, I was wishing for a more aerodynamic position than just being in my drops. Although, when I hit the hill I was happy to be on my road bike. It was the straightaways that got me dreaming of the Aeryn and a more aero position.

Kelli
Avatar On the bike, the triathalon body position is not a modified road position, which is why it is challenging to make a road bike feel like a tri-bike. The tri-position is not limited to extension on the bars by way of an aero add-on; the frame geometry is designed to introduce better aerodynamics and fully utilize the musculature developed from running - and even from swimming.
Most people who enter this sport will begin on a road bike and, when they fall in love with the discipline will realize they cannot maximize their potential without fully commiting to a tri-specific bike.

Avatar Kelli - I was fortunate enough to ride a lot of friend's tt bikes before I bought my trinity. I was surprised at how much "fun" I had riding it (it wasn't that harsh) and it climbed well (we have a lot of short steep climbs where I live so that was important).

Anyway, best of luck. I love my road bikes but i have to say it's a blast to ride a tt bike that's set up for just that. i went to a tt bike after listening to others stories about the # of aero bar set ups etc they tried instead of getting a dedicated tt bike.

Happy Riding.
Avatar Thanks. How do feel descending on your tt bike as compared to your road bike?

Kelli
Avatar There are 3 parts to descending for me - 1 the brakes - most tt bikes have these really cheap like brakes and cheap levers -the shimano 105s will actually stop you 2 - your position - the trinity fits me really well so i can get into a normal near the back or behind the seat position so i'm comfortable going as fast as i want/can 3 - the frame isn't so stiff that i'm getting punished on the way down, the stock wheels are kind of harsh all areo wheels are so for hilly tts or short tris i use a "softer" wheel
Avatar I just bought a Trek FX 7.3 and really love it. I also love mountain bike, but as I'm getting older I'm no longer interested in competition and speed, this bike I just got is perfect for someone who wish to do both, road bike and mountain bike. Well, it can't really support real mountain road, but general dirt road, this typed of bike will do.
