It's been awhile since I did a brevet, but I've been testing the new bike and gear, getting everything tuned in for next season. I've got several centuries and numerous 70+ mile days in the Green Mountains on the new ride, and just recently added the fenders.
The bike is my IF ClubRacer
I've added Scwalbe Marathon 28's. Not sure if I like them.
Fenders are Honjo's, smooth.
Lights are dual E6's powered by a Schmidt (I've also got a Cateye thingy that mounts on the fork as a front blinkie)
I love the Ortlieb gear. Everything I have of theirs is waterproof (I've ridden in plenty of rain lately).
Seat pack is the medium version. I also have the large which I used for last season's brevet's without the h-bar bag.
