How important is being on just the right fitting bike in a triathlon? Only the difference between winning and losing. And while there are many ways to get that perfect fit, the motorized, computer-controlled Guru DFU (Dynamic Fit Unit) will let you dial in that perfect fit. This uses electronic motors to adjust saddle and areobar position while you pedal. This allows you to feel the slight differences without jumping off the bike. This system even uses motion capture so you can see the differences as well as feel it!
