I've done a ton of searching but maybe I can get more of a clear cut answer here. Currently using 44cm bars on the road. My wife bought me some Pro Vibe 7s track bars for my birthday but they're 42cm outside-to-outside. My understanding is I should be looking at 38-40cm bars. This will be my first season on racing so I'll be doing every discipline at the track. What should I shoot for as far as sizing goes?
