Spring Extenders to suit WPS 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 21mm. 

The 21mm Split variant is a 3D printed spacer, which is held together with a dovetail joint, allowing fitment to shocks with stroke spacers and/or eyelet bearings (where the normal spacer won't fit over). It's 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 is around 15% stronger, thus allowing us to produce much more robust parts. Includes a performance washer to reduce friction. 

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

Great experience with Paul. Had an issue with my Fox X2, and sorted me with one of his EXT shocks in the time while a new part came from the UK. Really transparent service, explaining in details the issues and solutions. Chur!

"Proflow have been super important for me with bike setup. They're very professional and I love the fact they think outside the box to get the most out of suspension. I definitely couldn't have got my bike feeling the way it does without their help!"
