Rear hub on the FSA Non-Series off-road wheelset
My Sonder Camino Ti arrived in November 2020 with the FSA Non-Series off-road wheelset. After 9 months of mixed British riding, including a long, gritty winter in the Peak District, both wheels developed a bit of play and looked like they needed new bearings.
FSA/Vision have technical documents with lists of service parts for the wheels, but these use non-standard part names, and mapping these to the international standard was only possible once I stripped the wheels down and read them off the bearings themselves.
- Vision/FSA code: MR199
- Actual size: 15x26x7mm
- Quantity: 2
- Bearing code: 15267–2RS (2RS just means there are 2 rubber seals, which helps protect the bearing from grime)
- Vision/FSA code: MR200
- Actual size: 17x28x7mm
- Quantity: 2
- Bearing code: 17287–2RS (2RS just means there are 2 rubber seals, which helps protect the bearing from grime)
- The freehub contains a couple of the same bearings, but I couldn’t remove them, and ended up ordering a full replacement freehub (EL298).
As these have different dimensions, they need a slightly different-sized bearing puller.
To fit/refit the bearings, you’ll need a press with over-axle drifts because the captive axle gets in the way of a standard press once you have the first bearing in. There’s also a cheaper alternative approach if you have a socket set — Youtube is your friend there.
I’ve found Henderson Bearings to ship quickly and last a decent time, though I don’t know enough to say whether their “Enduro” branding is just marketing or a lot better for bikes.
