Easy to install
The change from the standard crank without a power meter to the Stages Ultegra LR power meter is super-simple and not at all complicated. Take off the crankarm on the non-drive side, pull out the crank with chainrings and axle on the drive side, push in the Stages/Shimano combination, bolt down the opposite crankarm, calibrate, done! Takes almost as long to do as it reads. Admittedly, I was quite happy about that because installing the Rotor InPower, like I had on my old bike, would have required me to change the bottom bracket. That's no big deal either, sure, but it's just easier this way.
The power meter is compatible with all 11-speed drivetrains by Shimano. Three crank lengths (170 mm, 172.5 mm and 175 mm) and three chainring combinations (34-50, 36-52 and 39-53) are available. The power supply of the measuring units is provided by standard button cells. Although they only last for around 100 hours, they can be replaced extremely quickly. And available almost everywhere on the road, for example at the petrol station or supermarket.
