I have a Brooks Pro Titanium. A Berthoud Galibier, a Rolls Titanium and a Perforated Flite Titanium.I never felt they were any weaker than my steel railed saddles. All quite expensive, but sure worth it for me for the weight savings and the coolness factor they add to my race bikes.I'd be more worried about aluminum railed saddles like the NOS Selle Italia Turbo SLG I passed on to my braver younger brother. NOS, cause I'd never trust a used aluminum railed saddle.
