Review on 🔧 Shimano CS-HG31 Altus Cassette Sprocket by Mike Phillips

Ideal for a quick second set of rims My commuter mountain bike can be used on and off road. Perfect for Shimano 8-11 speed hubs, so there is no need to use a washer with a 7 speed cassette. Has the same gear spacing as a 7 speed cassette just with an extra gear so I can still swap easily between these new bikes and my old 7 speed without having to do a lot of derailleur adjustment. Just don't use the biggest gear as my derailleur only has 7 gears.
