I've just purchased some middleburn rings for my m900 cranks but they don't seem to fit well at all. The BCD is right but the anti-jam pin is too long and digs into the crank. The middle ring seems too thick meaning the granny ring sits against it. Looks like I need a spacer for the granny ring and just take a file to the anti-jam pin but it just doesn't seem right.
If anybody could enlighten me before I contact Middleburn on Tuesday I'd be grateful. Thanks.
