The Kink Master BMX Seat Clamp comes with a unique bolt that is compatible with both a 5mm and 6mm hex key. The Master Seat Clamp is intended for those riders who can relate to the problem of not having the right tools nearby when you need them most. The Kink Master eliminates this problem, as you are more likely to find the right tool when it fits both 5mm and 6mm Allen keys.

The seat clamp is made of 6061-T6 aluminum and has a low profile design with a Kink logo on it.
