I know we’ve all been on 12spd for half a decade or more now, but I have a SRAM X01 11spd setup sat spare and a bike to put it on… The issue is that the X01 XG1195 11spd cassette has done maybe 3000 miles or so, but given that I changed chains religiously @ 0.75% stretch, it had 5 of them and the steel part of the cassette is in pretty good order (it’d work ok with a new chain, if not quite as well as new)…
The alloy 42T cog is however, pretty shagged!
I remember many years ago, Oneup components used to make this…
44T X-Cog Sprocket [ Sram 1×11 ]
It’s no longer on their current website…
I believe Wolftooth made something similar… But can’t find it.
Does anybody still make anything like this? Ideally a 44T, but even a replacement 42T stock size would be great. The bike will be light anyway so prefer to use my old 11spd stuff rather than have to buy some new 12spd stuff for it if possible, but I need to change the top cog on the cassette otherwise it’s a non starter really…
Or maybe there’s someone out there with a worn out 11spd SRAM X01 XG1195 cassette, but they’ve worn the lower steel cogs out, and not touched the top cog…? 🤔
