Performance Spring Extenders

Spring Extenders to suit our SiCr springs, and any other 38mm ID spring. 

CNC'd from an advanced homopolymer, the spacer not only extends the length of the spring, for useable preload range, but also reduces friction as the spring naturally wants to rotate as it's compressed. 

All this leads to a more consistent and reactive feel, increasing grip and giving you the same feel, all the time.  

Spring length will be extended by 28mm. Our 21mm version has been discontinued. The reason for this is that the new Rockshox Vivid Coil C1 shocks have less preload thread and so require a longer spacer. 

The 28mm Split variant is a 3D printed spacer, which is a 3-piece assembly, allowing fitment to shocks with stroke spacers and/or eyelet bearings (where the normal spacer won't fit over).
They're made in-house using Onyx - a flagship Composite Base material. It's a Carbon Fibre filled Nylon, which is much stronger than other 3D printed materials like PLA or ABS. In fact, it's around 15% stronger, thus allowing us to produce much more robust parts. Includes a performance washer to reduce friction. 
Full details can be found here.

Both can be used in conjunction with our Performance Adapters for fitment to 36mm and 35mm shocks.
