Doubtful

Nobody makes an off the shelf 10spd mech that works well with a 42T big cog yet. You can get OK shifting across the block with an 11-40, but not an 11-42 without a Rad Cage or Goat link or the like. 11spd mechs have been designed ground up, to work with wider ranges.

Also… Ratio jumps of more than 20% are quite noticable, and annoying in use. Anything of 20% or under seems to be acceptable, but above that and it’s less than ideal. For instance, I’ve been running an E13 9-44 11spd cassette for a while now, and it’s superb, but I do really notice the jump from the 14-17 cogs, a 21.5% jump (the biggest % jump in the block) which is quite annoying. The rest of the jumps (all below 20%) are perfectly fine.

E Thirteen do a 9-42.

I don’t know if that’s the norm though. My XT medium cage was ‘fine’ to begin with but it would never stay perfectly in tune and sometimes I would need to hold on to an upshift or double click to get into gear. Rad cage sorted all that and gave back the crisp shifting.

46 belongs on the front not the back!

10-42 makes more sense than 11-46, at least for me running a 28 or 30t chainring. Not as weighty, same spread (ish) as long as 30-10 gives you a decent ratio on the flat smooth bits.

Slightly OT (by 4T as it happens), anyone use the Sunrace 11-42 cassette? I’m looking at it as an option for a project and have seen some people recommend using the Shimano 11spd derailleur rather than the 10spd
