I have a 2009 Trek EX8 that came fitted with a nice SLX chainset and have just noticed that after 600 miles all of the teeth are dead apart from the odd 2 or 3 on each ring.
I tend to be a slogger rather than a spinner so dont really use middle ring as much as big but was surprised to see teeth missing all over.
Has anyone else experienced this? Is this poor quality rings or is 600 a good distance to cover on a set of shimano rings?
I have a Truvativ Comp-G chainset on my Giant that has done 1500 miles and they are near perfect with no teeth missing.
Any idea what rings will last longer that will fit as they need to be replaced?
Shimano SLX M660 44/32/22
cheers
