Brompton Pentaclip - Silver

The Brompton Pentaclip is designed by Brompton for connecting rail saddles (most saddles are like this) To the Brompton seatpost.

It can handle saddles with a rail spacing of 43 mm (centre to centre) and a rail diameter of 7 mm, though it can also cope with a reasonable variation in these dimensions. If the saddle’s rails are closer together the pentaclip may feel stiff when the angle is adjusted.

As well as connecting the saddle to the Brompton seatpost (all types - standard/telescopic/extended), the Pentaclip also allows for adjustment of the saddle. By losening the pentaclip the saddle can be slid forwards to reduce the reach required to the handlebars or backwards to increase reach.

In addition, the Pentaclip can be turned "upside-down" to give about an extra inch / 2cm of saddle height.

The Pentaclip / saddle need to be removed in order to remove the seatpost

Fitting instructions for the Pentaclip are included

Tools required: 5mm allen key / hex wrench

Note: in 2019 the word Brompton on the back of the Pentaclip was replaced with a logo of a Brompton 

Also available in black

A great solution

Hi, This is not a cheap part, but well worth the money compared to the common cheap pressed steel components. The saddle is firmly held, and the its neat and tidy looking.

It worked...

Bought to upgrade a (very) old brompton saddle for one of the new standard saddles. The product itself is relatively simple to fit- one bolt, works as expected. It was the service from Brilliant Bikes that was more noteworthy. Easy to find the part on the website, fast delivery, comes with Brompton normal high standard of instructions. Very happy.
