"The pits at nationals work like any other pit. If you don't have someone there you can still leave wheels or a bike and affect your own repair. Having someone there just makes it faster, easier, and means someone can hand you a clean bike every…"
Funny... I had a 42, single ring, in 2007. Always felt I wasn't able to keep up on the road sections, and wished I had the bigger ring. Went to Nats and got outsprinted (for 27th...) Went to the 46/38 for 2008 and had one of my best seasons ever. I've been thinking of going to a 44/36, though. Been struggling a tad this year with the climbs.

See you on the start line somewhere along the way!
