A couple of questions on tubulars. Got a nice set of tubulars wheels from eBay.Fr, and purchased some of the Kendra Veloflex tubs, 28’s. Riding the other day, 94 lbs in rear tire, and 4 miles from home, ka pow, and the rear tire blew out. Had Effetto sealant, too large a puncture, though. Bad luck, too much pressure, or what. Could I use the Vittoria universal sealant, supposed to do 7mm holes, and fix it?
