i need help!
fitting superstar plasma chain device
using the BB mount (no ISGtabs)
its all good except my granny ring tabs on my xt crank is rubbing on the inside of the plasma back plate
can i put a bb spacer between the chain guide backplate and the bb cup ? will this mess up my chainline or not leave enough axle for the crank? people say you only have 1 spacer on a 73mm bb and Hollotech II chainset ? can i run two (1 backplate 1 spacer) without issue?
only advise i can find on the net is to cut off the chainset granny tabs but dont really want to do that !!!!
so

1 2 3 4 5
1 bb shell
2 backplate
3 spacer
4 bb bearing
5 axle / chainset
sort of want to give 1x9 a go before I commit to it fully ! (im not so good on the up bits) so dont want to cut chainset granny ring tabs off = is this my only option?
I had to saw mine off on same combo
I had this and all i did was with a mini dremel type grinder was grind a small amount away on the plasma were the tabs were touching. My thinking was this was the cheapest thing if i messed it up. If that helps..
no non cutting options then 🙁
