Hey ya'll....I'm having a TT bike built out by my LBS. I delivered a set of Ultegra QR's to them today; they were going to wait until Ibrought them in to start the build. But they are so slow this season that they built the entire bike out and used a set of Speed Concept skewers that they had on hand with my Dicut 1400s. I still have to pick the bike up. The Speed Concepts look really nice, but I don't know anything about them. Should I switch them out for the Ultegras or stick to the Speed Concepts? They're not charging me anything for them. Thanks!
