Where It Sits
The published figures are 6 mm, 9 mm, 0.3 mm. Measure the old part against them before ordering. Outer diameter sets the lever the oil works against; thickness sets how hard it resists. A shim is a thin, ground steel washer, and the stack of them is what generates damping. A coned or marked shim is finished — it no longer seals against its neighbour.
Why the Original
A damper that can be rebuilt is a damper that stays on the bike; that is the whole argument for original service parts. Parts remain available years after a unit leaves the current price list, which is unusual in this trade. If you are unsure which number your unit takes, send us the model and serial number of the damper and we will look it up. We can check the number against the Öhlins exploded view before you order — just ask.
Getting the Number Right
21048-01 is the Öhlins number for this position — the same one printed in the service documentation. The published dimensions are inner diameter 6 mm, outer diameter 9 mm, thickness 0.3 mm — measure the old part against them if you are unsure. Outer diameter sets the lever the oil works against, and thickness sets the resistance. A worn or bent shim shows up as damping that has quietly drifted from the setting sheet.
Fitting and Setup Service
Öhlins recommends that its units are serviced by an authorised centre. We are one: rebuild, revalve and setup all happen in our own workshop.
