Has anyone got the SRP duar ace ti bolt kit on their ride? I am a self proclaimed weight watcher and am trying to get the thing to 15.5 lbs. How much does that shave and besides getting a race wheel like a Zip 303 what could be the biggest weight saving feature? I already have all dura-ace except brake calipers, and a carbon drop bar, and a deda newton stem. Granted, I am not trying to go to the stupid light components, I am still concerned about the safety of everything on the bike, but I think I can get it close to 15 without getting stupid light. The Deda stem is an exception, as there have been problems with the faceplates on last years models cracking and bolts shearing off. Any suggestions?
