Stallionforce, I guess the possibility of crashing is why we wear protective helmets when we race, even in TT's, eh? A time trial is the last place you would expect to crash.
Next major purchase for me is a disc, too. What do you think of the Hed disc, in particular?
You should come up and do the stage race here in the Comox Valley June 23-24. We'll have a 16km TT on the Saturday. Should be good. Also, we have a short Masters TT and a road race the week before.
