Seems like most modern 'DH' cranks are going over to 4.5mm thick chainring tabs. Educate me RideMonkey:
1) Is it possible to run a middle ring and big ring on such cranks? Seems like you'd need a special big ring for it to sit the correct distance away from the middle ring, but I don't see these advertised.
2) What is the standard chainring tab thickness? Is the position of the middle ring the same (measured relative to frame centreline I guess)?
3) I need to modify my existing bashguard to fit a set of these new cranks. Hence my asking 2) I guess if the position of the middle ring isn't quite the same it's not going to make a significant difference to chainline, and I can just tweak the position of the chainguide backplate (Straitline Silent Guide). So I can just machine off the difference in tab thickness from the inside of the bashguard...
I can't say I really see a need for thicker tabs. The only tabs I've ever wrecked were a set of the old, non-radiused Race Face ones. Thanks bike industry for giving me yet another standard I needed like a kick in the teeth...
