Mountain bike fit

Triathlon and road bike fits are discussed extensively on this site. I am looking for some tips to adjust my position on the mountain bike. Seems like it would make for a nice article if Dan were ever out of ideas (which, I realize, looks very unlikely). Thanks…

Thanks for the reply, -Tex.

I also go with what feels right, but I have been proven wrong for my road bike position. I wonder how the body angles translate into Mountain Biking and I would really like to see Dan’s knowledge applied to mountain bike riding. I should probably mention that I have a x-country bike and that is the kind of riding I am interested in.

While I am at it, I wonder if Cervelo ever considered building mountain bikes. Imagine a X-country version of the Prodigy!

Good question… I also have a X-country bike that I plan to race this summer and I’ve been fiddling with the saddle position. Right now the saddle is farther back and flatter than I would have thought was good, but it’s working for me. I, of course, have no idea what I’m doing as far as positioning on a mountain bike, it just feels good this way.

I’m 5’10 with long arms and legs and I ride a 56cm Kestrel KM40 with a shortish stem (100mm) and the saddle all the way forward. My mountain bike is a Large Trek Fuel 98 with Monkey Lite low risers, and my saddle is almost all the way back on the rails, and parallel to the ground.

Any advice?

Since we are on the subject of non road bikes… what is the difference between a road bike and a cross bike besides the brakes and the fork?

Could you take an old road frame and use it as a cross bike?

Assuming you mean Cyclo-Cross and not a Hybrid bike, the basic difference is the frame geometry of a Cross bike has a little longer chain stay for tracking stability, a higher bottom bracket for clearance and a larger main triangle opening to allow for shouldering the bike easily. Generally, the cross frames will ride much like a touring bike and often people will use them for commuting. They are great as a winter bike. But to really appreciate a Cross bike, you need to race Cross, it’s as much fun as you’ll have on two wheels. Awesome workout, and great for bike handling skills.
