Evening. I am thinking of ordering a 42T cog for my 1X10 setup. I know the manufacturers state to remove the 17T cog from the cassette to make space. What I want to know is if swap out the 15T cog and replace it with a 16T to even out the ratios, which I know has been done, will this part do the job:

I cant seem to find an XT or XTR 16T cog anywhere, so I thought a road cog from a 10 speed cassette might well work.

What do you think?

Many thanks,

Dom

I can't see why it wouldn't work, I've put a part of a 9 speed road cassette with the top 4 cogs of an 11-32 mtb cassette - worked well, shifted great and outlasted the rest of the bike!

There was another thread on this (unsurprisingly), consensus was itll work, i.e. the chain will run on it, change gear etc. BUT the teeth orientation relative to the other sprockets is not the same as an XT 16t, so it might be a bit jumpy/hesitant to shift.

Well you could always take a file to long spline tab so you could rotate it round into a better position
