I've converted my 3x9 el-cheapo mountain bike to 1x11 today. New XT rear shifter, SLX rd, chain, 32t race face narrow wide ring, SLX 11-42t cassette.
Chainline is way whacky. Looks almost a chains' width out in the middle of the cassette and I'm getting a fair bit of noise on the easy sprocket. My poor eyeball/ruler measurement of chainline suggests maybe 55-60mm from centre of BB which seems massive.
It's a MTB so BB shell is 73mm. Normal threaded job.
It is square taper. I think this might be where I've gone wrong, thinking that would work.. there is very little help online for this particular conversion question!!
I fitted my N/W ring to the inside of the Suntour XCM cranks. 104mm BCD.
I can think of 2 options:
1. Spacers on the inside of the chainring to move the ring inward.
2. New 1x crankset and BB. But I was trying to do this on the cheap-ish.
What say you lot? Is this a square taper problem.
Sort of option 2/b is pick up a cheap hollowtech crankset just for the spider/arms and keep my ring. New BB obvs.
Cheers
Rich.
