This is a great choice for you folks running track hubs or for those of you who still prefer to lock up the wheels separately.  Designed to keep your expensive fork, stem and seatpost where they belong.

• Standard seapost fits clamps up to 33mm wide (note - clamping surfaces must be parallel)
• Standard Ahead locking top cap fits 1-1/8" (1.125") steerer-tubes
• If your seatpost collar is wider than the standard skewer will accept, have no fear!  The Add to Shopping Cart section lets you pick and choose your skewer length.
• If your seatpost clamp's clamping surfaces aren't roughly parallel, you may wish to take a look at the Pitlock seat post clamps in the accessories section.
