I'm thinking about adding bar end grips for more hand positions. But I'll lose my mirror as a result, which stinks when commuting on busy roads. I guess I could get a helmet mounted mirror, though. I'm pretty sure I'm gonna upgrade my tires, brakes, and saddle over the weekend, at any rate, and I think I'm about due to pull the fenders off for the season. I guess I just wanna go faster and be more comfortable! I'm thinking Brooks B-17 saddle, KoolStop cartridge brakes, and maybe Conti GP4000S II tires in 700x28 (down from current factory Bontrager stuff in 700x32). Thoughts?
