This is Enduro's replacement face seal for 24mm (Shimano) spindle bottom brackets, sized 24mm x 37mm. It's a light contact silicone seal that sits directly on the bearing outer diameter, which makes it close to a universal fit, so if you're unsure which seal you need, this one will do the job. It's the same seal that comes with Enduro TorqTite Solid-Lube bottom brackets for 24mm spindles. Bearings last a long time, but the bits around them wear out, and this is a cheap way to keep things running clean. Put a thin film of grease on the back side of the seal when you fit it for best results.
