Choosing a Road Bike

Triathlon Forum

Has an article ever been written on picking a road frame? Is there a good resource out there to read more on the subject?

I am in the market for a new bike with a more traditional “road” geometry. When I say that, I mean that I am interested in finding something a bit more comfortable to ride day in and out than my 78+ degree Cervelo P3C, something more appropriate for joining group rides, something to race (occasionally), etc. All in all, just a complement to my “triathlon” bike (which I do love riding by the way).

Any ideas on how a triathlon-focused cyclist can pick an appropriate road geometry bike? While I’m asking, any thoughts on how a “road” bike should be set up if its purpose were to complement “tri-bike” riding? For example, if you prefer to ride at X degrees on your tri-bike, you should ride at roughly y degrees when riding a “road” bike.

Thanks for any thoughts,
Keith

The one article that comes to mind was on TomD’s site, it was the difference between a road and tri set up which might be a good place to start. Search his site, its an older article and has some good pictures.

Since virtually all conventional geometry road frames start with a seat tube around 73 degrees, you don’t have much choice but to start around there for the frame. Many people on this forum would consider Steve Hogg’s TT/Tri fit strategies, to be BS, but his road fit articles might have some useful advice for you. Also take a look at the fit calculators on some of the online sellers such as Competitive Cyclist.

In the same way that there are FIST-certified tri dealers, there are professional road bike fitters at many of the larger bike shops. As with tri bikes, the goals should be to find the right position that provides that ideal balance of comfort and power. Also keep in mind that any fit “system” will come with inherent biases and should be seen as starting point from which to modify for your personal needs.

Most seat tube angles are in the 74-74.5 range now.

The best thing for you to do is go get fit, and then ride a bunch of bikes. If the shop is any good they will set up several bikes with your measurements, so you are feeling the differences in the bikes themselves, not the way they fit. Road bikes are just like Tri bikes… everyone will ride and feel a little different, so make sure you ride a bunch to find what you like the best.

Don’t make any adjustments to “complement tri-bike riding”. remember, a good tri-bike position is, in essence, a good road bike position rotated forward by x degreesto allow a more aero position without sacrificing power. Just get a bike that fits you well, and set it up properly.
