I wore my WBs for the century I did yesterday and got some bad chafing. Not can't-ride chafing, but pretty bad. I was disappointed. I think it's because they are just a tad too big (and they don't make an XS).

Temp-wise I was comfy all day, though. But I don't think I'd wear them for another century. I'm looking forward to getting the the Sugoi knickers with the Ricaro2 chamois in the fall...TE is going to carry them this year!
