Sirris R38 2SC Rear Shock for Eride Pro SR

This Eride Pro SR shock is the Sirris R38 2SC: a 289 x 78mm piggyback with a 16mm shaft and independent high and low speed compression. It needs the Prickly R38 linkage, sold separately; the stock SR linkage will not work.

Specs:

• 289 x 78mm (length x stroke) - sized for the Eride Pro SR.

Sirris R38 Shock FAQ

Do I need a new linkage?

Yes. The R38 is longer than the stock shock, so it runs with the Prickly R38 linkage, sold separately. The stock linkage will not work.

Will the bike sit higher?

Yes. The R38 linkage raises the rear 25mm. Add the drop clamp on a Sirris F43 CMX fork to raise the front the same 25mm and keep the bike level.

Which spring do I pick?

Medium (90 N/mm) for 140 to 180 pounds and Heavy (100 N/mm) for 180 to 220 pounds, rider weight without gear. Sirris counts 15 pounds of gear into each range.

Is the SR shock different from the SS 3.0 shock?

Same 289 x 78mm R38 body, different springs. The SR runs 90 and 100 N/mm; the SS 3.0 runs 80 and 90 N/mm. Order the listing for your bike.

What does 2SC mean?

Two stage compression. High-speed and low-speed compression adjust independently, so you can soften small chatter without giving up support on big landings. Low-speed and rebound adjust by hand.
