Hi all,
Looking to go double and bash on my ML8 and was wondering if the bash needs to be the same size as the middle ring to work properly? I'm guessing the smaller the bash, the better ground clearance, but I currently have a 32T and think I'll change it to a 34 or 36 when it wears out, so is there any issues with using a 36T bash with a 32T chainring?
Nope should be fine - as you say, it's just the ground clearance that would change but it'll still work with a smaller ring
Thanks!
Yep - the chain will rub on the bash when you're in the small end of the cassette - at least mine did - SLX cranks, M660 32T chainring, Race-face light 36T bashring. You can try adding spacers to bashring until you're ready to move up to 36T chainring.
Ah, didn't think about that. May just got for a 32T then and flog it when I change the ring.
....and if you're planning on running 22/36 as your double, I'd recommend the Shimano M665 36T chainring, as it's specifically designed for shifting between a 22 and 36 (narrower profile, two stage ramps, deeper). I learned the hard way, started with a deore 36T and had all sorts of problems until I changed it for an M665.
