Shimano XTR FC-M970 Blackspire Super Pro crankset???

Postby couleur » Fri Jul 03, 2009 7:47 pm

Has anyone tried the Blackspire Super Pro cranks? I'm looking forward to get a M970 crankset to replace my current XT version. But I came across this Blackspire Super Pro which was bundled with the M970. What do you think?

I read that the M970 cranks teeth dont last long, so someone modified and build this version to replace it.
