My son survived his Pacific Coast ride last summer and will be going cross country this year. For those that remember our bike searching adventure, he ended up with a Cannondale T2000 (new, but prior year model). The bike was great, except for the rear rack, which broke en route. He rode with Shimano PD-M324 pedals (clipless on one side and platform on the other).
Folks on this forum recommend upgrading to Shimano M520 or M540 pedals. Others insist on having a clipless with platform to distribute the weight and recommend Crankbrothers Quattro sl.
My son will be riding 80-100 miles per day for six weeks.
Would appreciate advise from people who do this type of touring.
