I'm new at track racing and have just gotten into riding on a velodrome. I usually do Master's Crits, RR's and cross races. I'm 59, weight is 185, and my athletic background is that I was a decathlete back in my college days and sprinting and hard short efforts are in my blood. We just built the Velodrome in Cleveland and my first race was last Saturday. I purchased a lightly used Fugi Comp Track bike from a team mate, who has a Fugi Pro and also recieved a bike from a sponsor. My bike has the factory wheels. I also purchased additional chain rings and cogs to enable gear ratio changes. I hope to keep racing track for a few more years and want to do this properly.
In practice while riding fast in the flying 200 I have experienced a wobble in the front of the bike when deep into the turn at full on power. The shaking of the front end and bars while at maximum effort is disturbing. Sometimes the wobble showed up and other times the bike was smooth. When I would do short multi-lap sprints the bike never had the wobble. I've tightened the head set and tried different tire pressures.
Two weeks ago I did a flying 200 for time and had a 13.1" with no wobble. In the race last Saturday during my flying 200 I got the wobble in both turns and it impacted my time significantly. I did hit a max mph of 35.8 on effort but the wheel scrubbing killed my effort. I was in a 49/14 gear in the race. My time was only 13.6" and I had expected it to be in the high 12's. In the 500TT there was no wobble as the speed/effort was not quite as fast.
Can anyone provide advice regarding the wobble? Could it be me grabbing the bar too hard? Riding with my body too stiff? The wheel flexing? Something new riders need to work through? The bike does have a CF fork, but is my bike a POS? I have been working on staying at the measurement line on the hard efforts and don’t think I'm over steering with the right hand. In the 500TT I stayed near the line and in the 2K I know I spent most of the race on or below the black line.
