The following Pace forks relied on circlips[actually E-clips] to not only hold the carbons ON to the push rods[and upper assembly] but also to SUPPORT the carbons too by having more circlips in similar grooves on the push rods inside the dropouts with various shims/seals etc. It is best to change all of them occasionally as they spread or 'relax' after a while and can be damaged during removal and refitting. Always make sure the clips are properly in the grooves too.
RC36 Evo2, Evo3, Pro Class 2, Stealth.
RC38 Airforce & AF2, Airforce LT & ST/Race
I keep these clips in stock in packets of 10 if you need the correct replacements.
The early RC35 MXC/MXCD/MD also used circlips but they were a bit beefier than the later ones and dont seem to fatigue as much.
I keep these in stock also in packets of 2
Carge: the RC38 LT internals are completely different to the RC36 and share very few parts in common although they outwardly look identical. The travel on the '36[PC2/Stealth] is adjusted by moving a spring[note: not REmoving a spring!]. The RC38 is constructed with fixed length rods to pistons in the air chambers/damper and so travel is not adjustable. Although if you fiddle with the air pressures you can get them to 'shorten' but they wont work then
Result of not renewing the circlips occasionally:
I service and restore Pace forks
