Shimano XTR M9120 Gen 3 Dual-Sided Power Meter

Don't get lost in the ambiguity as to why you just landed that personal record on your favorite cross-country single-track course. Record your ride data with high-precision on the new Gen 3 Shimano XTR power meter crankset from Stages Cycling. There is undoubtedly a statement of freedom and a wild west trailblazing mentality that come when we saddle up on a mountain bike. But as a modern mountain bike racer whose quest is for the podium, it pays to add a power meter to your tool bag and bring a more informed eye to your performances. Grab your recovery drink and analyze critical race-data and work towards fine-tuning your strengths and improving upon your weaknesses during next week's training rides. A power meter blasts open the doors for personal, performance improvement by allowing you to become your own scientist and cycling coach.

New to the Stages power meter lineup is the dual-sided feature, which allows the efforts of both legs to be recorded and provide left/right balance evaluation, letting you see if you are overly dominant on one leg versus the other. And with individually calibrated crank arms, you can confidently interpret the data to within ±1.5% accuracy. Stages incorporates their trusted Active Temperature Compensation feature to the Gen 3, automatically updating the power meter readings as you ride through various temperatures and microclimates on your ride. Built-in cadence and power recordings of up to 220rpm and 5000w, respectively, mean you with have plenty of range to grow into as you smash downhills and punchy berms. Housed in the race-tuned chassis of the Shimano XTR crankset, all you need is a start line.
