Brompton Pentaclip for Rail-frame saddle - Black
Genuine Brompton replacement Pentaclip. Only Brompton would re-invent the saddle clamp. The Pentaclip allows a huge range of Height, Angle and Fore & Aft adjustment of the saddle meaning that no matter what height you are you are always guaranteed to get the perfect fit.
The Brompton Pentaclip is beautifully CNC machined from aluminum with copper and stainless steel shims. Using just a 5mm Allen key the clamp can be mounted forwards or backwards giving a huge degree of handlebar reach adjustment and even upside down giving an extra 2cm of height on any of the Brompton seatposts.
