I have a 98 GT Ricochet and it's a Large frame (I'm 6 ft). Anyway, everytime I come up to a steep incline and start going up, my front wheel comes off the ground and I have to stop or jump off. This is so frustrating since I'm getting much better on flats/downhills. What am I doing wrong? Is my bike's frame too big for me or am I just not positioning myself right? What can I do- I'm getting so frustrated, I hardly feel like riding when there are a lot of steep inclines. HELP!
