This Hexlox Universal Seat-Post Security Set secures an integrated seat post clamp (with or without a quick-release lever) that has an exposed hex bolt head that can be loosened by anyone with a regular Allen wrench or pair of pliers. This replacement bolt cannot easily be gripped by pliers, and when used with a Hexlox (sold separately), it cannot be removed by an Allen wrench without first using the Hexlox key.

What's included:

1 x Conical Stainless Steel Security Nut

4 x Steel Bolts - 25mm, 30mm, 35m and 40mm 

1 x Wave Washer for a perfect fit on quick-release clamps (Only delivered with the M6 Set)

*Hexlox is not included - add a Hexlox (and a matching key) to your order to protect your saddle against theft
