    I have it on my Orbea Rallon for over 1 year. Works great, no troubles. Chain rubs on the plate when on small ring front and lowest gear at back, but that doesent bothers me.

    Great item, but I'm not so sure about 22T compatibility with ISCG 05 version, at least on my chainset chain rubs the guide plate even with no washers between guide and frame.No big deal but need to use an extra spacer on BB. Unexpectedly, because I didnt see it mentioned, it did come with the required bolts for ISCG 05 fit, even if those are a bit long.

    Great product great price ! The bearings (kind of) went after a long time in gritty weather + snow (riding in the alps the whole year round). So I think it's kind of normal. A bit heavy though (roughly 300 grams if my memory is correct). Great product, recommended !
