Hi, I'm 16, going to be racing Crits and Road Races next year (in a month or so) and I was just wandering around the USAC website when i saw something on junior gear restrictions. They call it "junior rollout" (link here: http://www.usacycling.org/encyclingp...ry.php?id=4203 ) and i had to buy a new cassette a couple days ago. I have an entry-level 8-speed bike so it was only about $40 (not that big a hit). Now, the hardest gear is a 50x13. I measured it and it is about an inch or so over 26 feet, is this alright? Or do i have to block off the gear so i have a 7-speed and the hardest gear is a 50x14?
As a second question, since i have a spare cassette now, i was thinking of putting the race-legal cassette on a new wheelset (Got enough money for christmas to do so). Would this be smart to have a race wheel set with high-end tires and the such and a training wheelset with the stock rims and tires, or just race and train on the same wheels? Thanks for any input on the subject.
