Descended Thunder Ridge in May, in the rain. The "technical" portion on chipseal. In the rain. Tektro R741 calipers, Modolo aero levers pulled all the way on wet Fulcrum Racing 3.5's kept the speed at 26-28. I learned a lot about bike handing and the tire adhesion of Tufo tubular CS33's. Not fun from a safety standpoint. I tore the bike down and, other than wet, it was just dirty.

It's part of the deal.
