Track sprocket won’t fit. They’re threaded. DX ones are ok but will eat through an alloy freehub body if you have one. I’ve got a DX on a ratbike and an On One thing with a wide base on another. Superstar do a cheap wide base one but reviews speak of varying quality.
I broke my absolute black one on its first ride. Plus it has worn really badly, even with a brand new chainNot impressed. Having an email fest with them atm trying to get it sorted. Personally I think I’d go with a surley one now.
On-One Groove Armada is a good balance of price and durability IME. I’d avoid Superstar SS alloy cogs – mine was made of Brie and self-destructed in no time. Surly about the same as the On-One but a bit more spendy.
