These come with some mountain cassettes so you can put them on a road hub. Don't forget to check your box or the listing for the cassette. Just buy one of these in case you lose it when you remove the cassette for service.
I had the R1 on my road bike and bought the R3 for my gravel bike. Used it on my ride across NY,390 miles. It was comfortable the entire ride. This was a "B" grade purchase, not sure if that is the right terminology. The discount was super. It appeared to be new. No scratches or any indication it had be used. The price was great.
Great price for power. Unfortunately I cannot get the non power side to stop squeaking. Started day one. Iï¿½ve eliminated all other potential culprits and have tried greasing, lubing and properly torquing to the right Nm setting to no avail.
