RockShox and the Suspension Side of SRAM

RockShox built the first mass-produced mountain bike suspension fork, and the brand is now the suspension arm of SRAM. That matters in practice, because the forks, shocks and droppers are designed to work with SRAM's wireless electronics rather than around them.

The platform names have stayed consistent for long enough to be useful shorthand. SID for cross-country, Pike for trail, Lyrik for the heavier end of trail and enduro, Zeb for the longest travel, with Super Deluxe shocks and Reverb droppers alongside them.

Dampers, Air Springs and What the Names Mean

The fork chassis is the easy part to see. The damper is what you actually feel. Charger 3 RC2 dampers give independent high- and low-speed compression adjustment, which is the difference between tuning for small chatter and tuning for big hits.

DebonAir+ air springs handle the other half, with a larger negative chamber that keeps the fork moving early in the travel. Between the two, a fork can be set soft off the top and still hold up in a compression.

What We Stock From RockShox

The range splits into four groups:

  • MTB forks. SID, Pike, Lyrik and Zeb in 27.5 and 29 inch, across travel options, with Boost 15x110mm spacing and tapered steerers.
  • Shocks. Super Deluxe air and coil options for trail through downhill frames.
  • Dropper posts. Reverb AXS wireless posts in 30.9mm and 31.6mm, from 125mm to 175mm of drop.
  • Fork service kits. Full service kits, seals and suspension oil for keeping an existing fork alive.

Getting the Fitment Right

Four numbers decide whether a fork will fit: steerer type, axle standard, wheel size and travel. Most modern frames want a tapered steerer and 15x110mm Boost, but check the frame rather than assuming.

Travel is the one worth thinking hardest about, because going longer than the frame was designed for changes the head angle and the warranty. Crown offset matters too, with 37mm and 44mm options changing how the front end steers.

A fresh fork or a service kit is the closest thing to a new bike for the money, and the small parts are here as well as the complete units. Free delivery applies to orders over $99, though forks ship as a bulky item.
