Hi everyone,

Can someone kindly explain - in lesser detail is fine - what 66 degree chainstay means? In relation to a Shimano Deore XT front derailleur.

For someone replacing a front and rear derailleur on a mtb, what does it mean?

Thanks!

I believe it refers to the angle between the chainstays and the seat tube. The orientation of the front derailleur cage relative to the chainrings and chain will vary with this angle.

yeah I tried to fit a front mech to a bmx that had a steep angle on the stays.
couldnt get it too work as the mech was always too high
