BikeFit Pro Brother Russ on Cross Fit

As we transition into cross season I asked Russ Stevenson to share a couple considerations for us during a cross fit:

"Relative to a road bike - I consider a slightly shorter stem. This will help move your body mass off of your bars a little more. You want the front end to be loose and free, no pressure. Leaving your stem the same as your road could work if the head angle, rake and trail were all much more slack; but that all depends on the bike. I would never tell someone to use the same stem as their road bike if the bike was super steep….. that's a crash waiting to happen.

I would also consider lowering your saddle 5mm or so. The simple on/off the bike aspect warrants that alone...not to mention that in cross the effort is short and very hard. The rider’s body tends to hover on the saddle, never really sitting static like on a road bike. Add in the bumps and obstacles and the body mass is continually up and down on the saddle. Lowering the saddle allows more room to move and absorb shock...which all means a more stable, calm bike.

…..ok and this too... bring your hoods up, especially if you are running a deep bar. Having the hoods flat like many road bikes opens the rider up to sliding forward when things are sketchy. The higher hoods let your hands sit more comfy and take shock better. Look at all the pro's, they all run their hoods sky high. With a compact bar curve, you could flatten them some but still higher than a road bike.

Two hole Cleat Wedges are not always the best for Cross racers with the constant mounting and dismounting. One BikeFit brand only ITS (In The Shoe) wedge may be considered and of course a good insole are the way to go. I have been happy with Cycle Soles as my choice for insoles."
