    I bought a red one of these to replace the standard black QR on my Cube Reaction. As long as you can live with it not being QR, this is a very light and good looking alternative. It's very nicely finished and machined and looks neat and slick on the bike. Yet again another nice piece of kit from Superstar. Check out the nano pedals, they are gorgeous.

    Looks perfect in my trek scratch, but the bolt on the clamp was too short had to change to a longer one! The product looks brilliant anyway, effective! Just think they need a slightly longer bolts on them!

    Was looking for a superlight bolt clamp, this obviously isn't it, which is a shame. Bolt not stainless either. Good value for ̏6 but not what I was looking for, so I fitted something else to my road bike. HINT - why not do a bolt-up version of the superfly clamp??

    First thoughts were it looked a little light weight and flimsy - but not so... holds my post really solidly. Excellent price too.
