Noobish questions as I am just getting into track cycling. All answers are appreciated. I''ve got a 2011 Blue TR250 AL frame (53.5 ST, 55 TT)

1. I assumed it would fit any 700c wheel. When I take off my front Easton EA90 wheel with 25mm Gatorskins off my road bike, the tire basically scrapes the top of the fork, almost like the combination of the wheel and the tire are too large for the track fork. Do I need to get 700c wheelset with smaller tires? 23 or 19 etc? I don't want to use my Eastons, I just wanted to try the fit. Any sub $400 wheel recommendations for track use?

2. Bike came in with DuraAce 7700 octalink BB. As I don't want to spend $400 on FC 7710 Cranks, do I have any other options with this BB? If not, what combination of BB/Cranks would you recommend for beginner track use?

Cheers
