The blackspire's were heavier, by how much I can't remember. They also lasted more than 1 muddy ride too
I didn't get the 960 cranks until a year after they'd been released. In that time plenty of my racing mates has been through a few middle and large rings. There was no choice in those days, as the Blackspire's hadn't been released - you HAD to go with the 'cheese' ringsjOie said:Thanks for the response...I've heard from many sources that the XTR's wear out fast, but nothing specific. It sounds like you had problems with them...details?
Since this is the weight weenies forum...I would say go XTR or custom.SOFTBUTT said:The Blackspire rings are as follows
Granny - 28 grams
Middle - 46 grams
and guard - 80 grams
There's also the Middleburn rings.
