I have seen a couple of very nasty crashes caused by people taking their hands off the bars when they've touched shoulders and not known what to do. Other things that newer crit racers need to be aware of are:
- Don't move up on the inside of a corner, unless there is a whole column of riders doing this.
- When you're first wheel and the person on the front comes off, PULL THROUGH! Even if it's just a token turn for a couple of seconds to let the rider come off the front. Sticking to the wheel like glue causes the whole bunch to stall and can lead to a rear end pile up. If a 10 second turn will lose you the race, drop a grade.
- Don't sprint from any more than 8-10 riders back, unless you're very wide and have a clear run.
- DON'T SIT UP COMING INTO A SPRINT! Just because you aren't in a position to win doesn't mean you just freewheel to a stop. If you're in the middle of the bunch, keep your speed up.
There's other things to consider, but these are the main safety concerns I have with new riders in crits.
