EZ Suspension Block

Another item I have designed which has also had a big positive reaction is the EZ Suspension Block:

• Extra Firm Suspension Block in TPU materials (colours at the bottom and on the buy page).
• Similar firmness to the CHPT3 red block (stiffer and higher performance).
• Aesthetically blended shape.
• Increased ground clearance when folded.
• 3D Printed with 3 different internal density zones.
• Less than 35g (replaces latest standard block and end plate which is 37g).
• Can install Striker Plate upside down to prevent rear triangle locking.



Firmness

It is generally regarded in order of firmness from least to most :
1. Brompton Original.
2. Brompton Standard (as fitted to new Bromptons).
3. Brompton Firm.
= Brompton CHPT3 red block.
= EZ Suspension Block.
6. Joseph Kuosac Suspension block.

I would say that my block is comparable to the Red CHPT3 suspension block. Here you can see the stiffness on a Brommie :


Instructions

First is to familiarise yourself with the Brompton suspension block removal and assembly procedure, as described in this video by Brilliant Bikes :

Re-use the main pin/bolt and washers from the standard Brompton suspension, just replacing the rubber block and Striker Disc with the EZ version.

The existing pin is a tight fit in the existing Striker Disc, it takes a small tap with a hammer to push it out. Hold the components as follows and tap out the pin :

Once removed you can press the pin into the new Striker Plate by tapping the head of the pin while supporting the plate underneath with the new suspension block itself.

The re-assembly is now the same as fitting a normal suspension block as described in the video above.

Tighten the main pin enough to close up all the gaps but do not over tighten otherwise the Striker Plate can over bend.
