Hi All !, has anyone ever installed the KCNC lightweight alloy chainring bolts on a XTR set up? I currently have a set of 5, and it looks like if I shorten the nutsert, I could get them to fit. I would have to order a second set though, but I wanted to see if anyone had any durability problems. :?:

If the bolts are too long I guess you're using an XTR 960 crankset...? KCNC do make shorter chainring bolts for single rings... these do fit the XTR960. Cant comment on the durability though...

KCNC has two types of bolts...SPB004 Compatible with XTR FC-M970 Crank (8.5mm Bolt&6.5mm Nut) and the SPB003 Compatible with XTR FC-M960 Crank (6.5mm Bolt&4mm Nut) and KCNC TK1....so far we haven't had any type of issue with these.

Well, I can personally recommend NOT to buy the wrong size for you crankset. I filed and ground down my longer KCNC alloy bolts and almost ruined them. I was able to shorten them with a grinding wheel then filing them smooth. But I had a hard time holding them in a pair of vice grips with rubber tips. I ended up scarring some of the sides. If they weren't so darn expensive I would have replaced them with the proper size.

Thanks.

i purchased a set on ebay back in august from yan_kelly, they seem to be holding up well & kept their torque

set was in red for the mrs's XTR M970 + triple Rotor Q-Rings, no probs installing them but was extra cautious winding up the threads

Edited. The pics were just a wee bit larger than permitted on the forum. :wink:

Merry x-mas to all, by the way! Powerful Pete.
