I like the idea of the 511% range but have heard they wear quite fast and the shifting isn't great?
Using on an X01 mech.
Can't comment on wear rate as it's on a bike that only gets used a handful of times a year.....but.....in the first 15 miles the biggest ring bent. Lbs straightened it and it's been fine.
Shifting must be ok as i can't honestly say it is any worse than the original Sram cassette it replaced.
Nice to have the extra range on steep hills.
I think I've heard of the alloy big ring bending before?
Were you out of the saddle giving it some at the time?
I honestly can't remember, i don't usually ride out of the saddle climbing, more happier spinning up climbs so i doubt it was that....
I must admit i fitted it myself and i only adjusted the b screw, not the high or low on the mech so it could have been poor set up.
OK mate,
And the shifting is pretty decent? What cassette were you using before this one?
I gave up on mine, it ran perfect for about 3 months then started skipping in the 9t , 10t & 12t under load. Particularly the 12t.
I tried chain tension, b limiter screw but nothing worked. I replaced those 3 cogs and it worked again but only lasted 2 months. I was running a 28t front ring and wonder if a bigger front ring might of helped, though I don’t see how. The newer ones seem to have changed design a bit and are only 2 pieces not 3 so maybe this is something that’s been sorted. It was a real shame as when it worked the range was great.
It was a Sram XO1 10-42 cassette and i am running an XX1 rear mech
Cheers guys....
Tempting but i'd not want to have issues after a few moths!
If one comes up new at a good price I mist take a punt. 😉
I thought I’d read that Sram mechs (non-eagle) weren’t very happy getting up into the 46 tooth ring.
Seems to be ok from what Ive read. Plenty seem to be running Sram mechs on the 9-46.
Cheapest I can find for the cassette seems to be £202. Fair chunk of money!!
You can get a full Sram GX Eagle group for £340 ish from CRC can’t you?
Just trying to find the review I’d read where Sram mechs were struggling to hit the biggest ring and I’d mixed it up with the sunrace 11-50 cassette. Apparently Sram mechs generally didn’t work with that but Shimano ones that claimed up to a 46 tooth worked ok with it.
Ah, I see mate. So sram on a 50 tooth is an issue?
