I tried installing my Red cassette (10spd) on my (old) powertap wheel. The lock ring plate actually covers up a small area of the trough for the smallest ring.
Rephrased: the diameter of the lock ring is slightly large (overlapping the small toothed ring (11 tooth). Meaning the chain rubs on the lock ring without settling into the trough of the smallest ring.
Anyone have experience or advice? It’s last year’s cassette (I think) and it’s 10 spd… umm… it’s sexy and light… and red.
I’ve replaced the Red lock ring with a PG970 lock ring and that is small enough in diameter to allow the chain (PG1050) to catch deeply in the trough.
Thanks in advance. I don’t mind the PG970 lock ring. But it annoys me that I’m probably missing something.
Tough to visualize from your description. I use a mixture of cassettes, Ultegra and SRAM Red and have no issue. As Vince indicated you do loose the spacer when using the SRAM cassette.
Also I have to adjust my rear derailleur when changing wheels. It sounds like that might be what you need to do. I usually keep certain cassettes on certain wheels so it has been a while since I have switched cassettes on a wheel but it is very likely that would also cause a required adjustment on the rear derailleur. It is actually very easy to do and highly recommend learning how to do it.
And by spacer, just to clarify, it’s not any of the cassette spacers. It’s the tiny spacer between the top of the cluster and the hub. The vast majority of Shimano-ites don’t even know it’s there until something like this happens…trying a SRAM. It’s only .5mm, but it sure does foul up the lock ring scenario!
You have a wrong lock ring on your RED cassette. Go to a local bike shop with your cassette and lockring and compare your set with a brand new one. I have three RED cassettes and none have your problem.
You are probably using a 12t lock ring with an 11t cassette. The lock ring needs to be matched with the cassette, or you get the problem that you just described.

Some Sram FORCE cassettes indeed start with a 12 tooth cog but all Sram RED cassettes start only with an 11 tooth cog. So your lockring might not be a RED but a FORCE.
