Thomo Posted December 16, 2016 Posted December 16, 2016 Is there any difference between mtb/road.?I know the difference is normally q-factor, but I can't seem to get clarity on this via the internet specifically for this Stages carbon crank arm.Thx.
xcd Posted December 17, 2016 Posted December 17, 2016 As far as I can understand it. You can get different spindle lenghs. When fitted in your BB will give you the correct Q factor required between MTB and road.

xcd Posted December 17, 2016 Posted December 17, 2016 Sorry I forgot to mention the Q factor of a road bike is normally 150mm and a MTB is 170mm. So buy replacing the spindle to a longer one on a MTB it will give you the necessary clearance required to miss your chainstay. ( They seam to have a big range of spindles available )
PeterF Posted December 17, 2016 Posted December 17, 2016 Not sure that the spindle is an issue as the spindle is attached to the drive side crank arm and the Stages power metre replaces the non drive side crank arm. You do need to make sure of crank arm length though as most road cranks are 172.5mm long whereas most mtb cranks are 175mm long.
Thomo Posted December 17, 2016 Author Posted December 17, 2016 I speak under correction, but isn't q-factor influenced more by the actual shape of the crank arms.?
Mongoose! Posted December 17, 2016 Posted December 17, 2016 Will a GXP mtb left arm crank fit into a GXP road spindle? ( (referring to the crank bolt only) It is no brainer to buy the same length on both sides. If the Q factor differs on the two, it can be fixed with spacers to get even distances between the two chain stays and crank arms?
PeterF Posted December 17, 2016 Posted December 17, 2016 "It is no brainer to buy the same length on both sides." You would think so, yet I have seen guys selling their Stages power meters here on the hub for this exact reason.

NotSoBigBen Posted December 18, 2016 Posted December 18, 2016 After some serious knee or hip pain....lolOn the left hand side only I guess ????
Thomo Posted December 19, 2016 Author Posted December 19, 2016 A couple of responses but still no answer. LOL
jcza Posted December 19, 2016 Posted December 19, 2016 Will it fit? YesWill it work? Probably not without modification or pedal extenders.Diff between road and MTB Q factor 25mm-30mm depending on which model.

Spinnekop Posted December 19, 2016 Posted December 19, 2016 I don't know.....I can only comment on experience..... Moved my Cannondale SISL crank arm from road bike to MTB by removing the left crank arm and installing the Stages left arm.No other modifications or spacers or BB lengths or nothing.
