Back from the bike shop, where I purchased a set of 0.6mm shims ( 75 cents a piece!). My past experience has been that this prevents the chain from being sucked down between the middle and inner rings. My favorite mechanic suggested a trick that should help with the gymnastics of holding all the parts together during assembly. Put a bit of greese on the spacer to hold it in place.
I run a 9 speed chain with a 9 speed cassette. I have never seen this crank listed as 8 speed only. Michael On Saturday, March 2, 2013 12:53:26 PM UTC-5, Patrick Moore wrote: > > Hah!
