Most people lock their bike up so that someone won't take it, but the truth is more time than not parts are stolen off bikes because they are a lot easier to take and conceal than the entire bike. Pinhead''s solution to keeping your saddle on your bike is a Locking Seat Collar with Pinhead''s unique locking pattern.
The Pinhead Locking Seat Collar includes shims for 28.6mm, 31.8mm and 34.9mm seat tubes which should fit most bikes.
While the Pinhead locks might all lock similar, they are unique and each is coded with a 9 digit code on the key. It is recommended that you register your key here as it will be the only way to get a replacement should you loose the key.
Includes shims for most common frame sizes
Locking head has a unique pattern
Includes 1 key with integrated keychain
