God Love You John: It's pretty easy-silk loses about 20% of its strength and a lot of its elasticity when water exposed. Silk actually retains a lot of water. Since a good hand made silk tubie can have more than a Km of silk you're going to end up with a deformed tire and, mostly likely a flat. In wet environments, in order to have the good ride of silk and water resistance too some tubulars are heavily impregnated with chemicals that resist water. On the other hand, for track use where water exposure is unlikely, FMB will make a silk tubular tire with no coating-these are faster and lighter than the chemically impregnated ones. Check on FMB's site for the details. George George Hollenberg MD CT, USA
