I'm a fairly tall guy, about 6'3" with a long cycling inseam. After a professional fit the other day, my position didn't change much on my bike, nor was I on a bike the wrong size. Though I guess it is very "quick" and short wheelbase ('05 Fuji Team SL) for its size (60cm).
When I was sprinting yesterday in a training crit, and pretty much everytime I sprint, I feel very scrunched up/unstable and my back wheel jumps around a lot. For reference I feel good and stretched out when just sitting and riding normally.
So my questions are these:
What do I need to work on to correct this problem, technique-wise? (i have done some of the really "slo-mo" type training techniques, as written by carpedieme racing, stuff to try and smooth myself out, but hasn't helped much yet, is there more I can try)
When I'm in the market for a new bike, which is soon, what types of things should I be looking for? More/Less trail? Longer wheelbase? More/less rake? (I guess I am asking becuase I'm wondering if it's all technique or if in the future there are things I can look for in the geo of the bike to help me be more stable)
Thanks for input in advance!
