Sirris R38 2SC Rear Shock for Arctic Leopard XE Pro S, Enduro, R

This Arctic Leopard shock is the Sirris R38 2SC in 269 x 68mm, and one part fits all three XE Pro models: S, Enduro, and R. It needs the TMB R38 linkage, sold separately; the stock Arctic Leopard linkage will not work.

Specs:

• 269 x 68mm (length x stroke) - sized for the Arctic Leopard XE Pro.
• Piggyback reservoir, steel spring.
• 2SC two stage compression: independent high-speed and low-speed adjust - tune small chatter and big hits separately.
• Tool-free low-speed compression, 18 clicks; high-speed compression, 24 clicks (20mm hex); tool-free rebound, 24 clicks; spring preload adjust.
• 16mm hollow shaft, induction hardened steel with hard chrome, the same shaft as the larger Sirris R46 - moves a lot of oil through the main piston for full-size damping feel.
• 38mm CNC billet 6061 aluminum main piston, type 3 hard anodized.
• Seamless 6061 aluminum body and spring retainer, type 3 hard anodized, ACME thread.
• Chrome plated, teflon-lined spherical bearings top and bottom.
• HNBR seals; MCU bottom-out bumper.

Fits these models:

• Arctic Leopard XE Pro S (with TMB R38 linkage)
• Arctic Leopard XE Pro Enduro (with TMB R38 linkage)
• Arctic Leopard XE Pro R (with TMB R38 linkage)

Required companion part: the TMB R38 linkage (sold separately).

Sirris R38 Shock FAQ

Do I need a new linkage?

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

Does one shock fit the S, Enduro, and R?

Yes. Unlike the F43 fork, which has a separate R version, this R38 fits all three Arctic Leopard XE Pro models.

Which spring do I pick?

Medium (110 N/mm) for 140 to 180 pounds and Heavy (120 N/mm) for 180 to 220 pounds. Use your weight without gear; 15 pounds of gear is already counted.

Does it pair with a Sirris fork?

Yes. The R38 is tuned to pair with the Sirris F43 CMX fork, and Sirris builds an F43 for the XE Pro S and Enduro and another for the R.

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.
