Specialized 93-95 FSR shock

The original first generation Specialized FSR used a 5"x1" rear shock. Only Risse Racing makes new shocks in that size. Unfortunately, this makes the shock not compatible with the Schwinn Sweetspot.

The early FSRs also had the Alps shock with a much more durable steel shaft on it. Even though it's heavier, it's preferred since the shaft cracking is a common point of failure on the Alps.


Sweetspot pivots

Aluminum Homegrown bushings: 44mm OD, 38mm ID, 2mm flange thickness
Exact Homegrown bushing measurements: 44.03mm OD, 38.06mm ID

S-series and Carbon (both S-Series and Homegrown) bushings: 42mm OD, 38mm ID


Rich Adams: Looks like the HG bushings need to be custom made from Tercite (igus G300, L280), but you can still get the bushings that fit the S bikes and the carbon FT. The length will need to be cut down, but that's not too hard. Not positive, but I'd bet these would fit perfect.

Mark Rhomberg: I remember the best bushings we tested were specially machined from a blue material. Poly pro with Teflon embedded? They were too expensive to produce en mass. I think 6x more expensive. The close second was the HG bushing pictured above. Igus bearings tend to chew through the aluminum pivot so make sure you replace the pivot.
