In 2008, RockShox completely revamped the SID fork, upping the stanchion size to
32mm and increasing the stiffness of the lowers through the use of bushing "Power Bulges" and a newly engineered arch. The
new SID lowers have a shallower seal head, preventing the use of our standard "32mm RockShox Seal Kit." The "Tora"
forks also require this compact version of the 32mm seal kit.
Have an earlier SID fork with 28mm upper tubes? Be sure and check out our 28mm RockShox fork
seal kits here:
