When using our Phlebo Buffer, it adds a little bit of height to your frame, which can mean your stock UFS bolts may not grab as many threads as it once did before installing the buffer. We are now offering extended UFS Frame Bolt set to go with your buffer setup. Depending on the frame and the boot setup, it may not even be needed, but for those that do need it we have you covered. Standard size UFS bolts on flat boot setups are usually M6 x 16mm, these sets are M6 x 20mm, a full 4mm longer than most stock UFS bolts. Always remember, blue loctite is your friend!
