Need to fit a chain guide but have no ISCG lugs on my frame. I have a standard cup sealed BB. Cant seem to see how they fit as between my SRAM crank and the B/B there is nothing to secure it. was looking at a cheap one like the Superstar £16.99. I am riding 1 x 10 with a 42T on the rear. Rode yesterday for the first time without a front mech on. Chain came off 3 times when getting speed up on rough ground. I suppose i could put the front mech back on. Any ideas, info, advice.
