    XT vs. XTR crankarms, nondrive side weight?

    I've been looking all over and haven't been able to find this detail. Does anyone know the weights of XT (780/5) or XTR (980/985) non drive side cranks arms? I'm also curious if anyone has ever mixed XT and XTR non drive side crank arms (I assume they're compatible...)? Reason for asking is trying to determine if the $100 more for xtr is worth it if getting a stages powermeter, given I currently use XT 780 cranks.

    I only have weights for M770 and M970 left crankarms. I would imagine not much has changed between newer models. M770 and M970 left crankarms are not interchangalbe due to different splines. I do not know about the newest versions.

    M970 Left crankarm - 193g

    M770 Left crankarm - 224g
