interesting hob nob! is he running the stock eagle chainring?
in terms of quality mboy I have no complaints, wear seems incredible on the cassette, chains and it shifts very nicely indeed, setup seems spot on, on mine
the only issue ive got the is the noise, its quietened down by a freshly lubed chain (ie wet still), but as soon as that starts to dry it doesn’t sound good at all, in fact when its wet outside and crap weather it sounds better than when its dry and dusty, and its not the chainlube I’m using, ive used 3 different sorts (all of which Ive used before and never had the noise) and its still the same
