Wanted: free/cheap 11-46T 11s cassette (for sizing)

I'll take a shit cassette to test if 46T will work on Ultegra Di2 and/or GRX 2x

Or if you've got a new one let me know how much you want for it.
Best I can see is £95 at Merlin but perhaps there's a cheaper Sunrace option...

£63 for a SunRace Csmx8 1146t 11 Speed Cassette

biketart has 11-46 SLX for £52
am also on the lookout to test for sizing.. (11-46 on Rival 1)

Thanks, found a used CS 7000 Shimano one on ebay for £40. Will be giving that a go.

If it doesn't work and is in good condition, drop me a message

Will do. Condition in pics looked pretty good so it should easily be good enough for a test.

Or go to 50T :)

1x only it reckons but then, I've run everything else out of range for a while so why listen to them and their silly rules? :)

I had to fuck around with an slx derailleur to get it to work with an 11/46, and shifting it shit. When I can be bothered I'll go back to 11/42.
I've the 1by di2 grx derailleur running as 2by with an 11/42 fine.

I'm not sure where I was going with the above ^^

Yeah, 11-42 works with stock Di2 DRX and Ultegra shadow cage (1x RD w/ 30/46 or 34/46 rings).
I've never tried 11-46T though. Do you remember the chain length you used?

If you need more range for 2x Specialties make a 28t inner ring for GRX. Reckon 46/28 might be manageable for a GRX fd. If not they also make a 44t outer

I don't have GRX cranks though, just shifters and RD so I don't think I can go lower than 30T on the P2M or lower than 34T on the Quarq. That's why I've grabbed a 46T cassette to test out.
Another option might be to move my gravel cranks with the 30T onto my road bike for the super hilly stuff like Pendle.

Found a chain that should cope with the massive cassette:

Got a SRAM 1230 11-50T Shimano freehub compatible cassette if you’re still looking for testing materials

I haven't got to testing the 46T yet (pulled cranks off gravel bike for road bike in the meantime so will need to swap BB and reinstall). How much do you want for this monster?

Just realised it’s 12 speed….

1230

Ah, I should've clocked that. Nevermind.

Yeah, me too!

@hippy any findings with testing the 46T cassette? Asking cause I am about to do the same.

Ah, sorry, not touched it. Gravel bike went to another country so I've been riding MTBs.

I still need to buy the DI2 stuff for the Crux. Won't be for a few months probs unless I sneak it onto the grrl's Mason.
