Stages Power L Shimano XTR M9100/9120 sport factory

Stages Cycling has quickly become the leader in power meter technology and is currently the largest manufacturer in the world.  We have ridden, tested, and sold Stages power meters since their release, and they have proven to be the most simple, reliable, compatible, and durable power meters we have ever sold.  It is very rare that we have experience a warranty issue, but when it has occurred Stages was quick to trouble shoot or rectify the issue to the customers satisfaction.  Stages has continually improved their products, added dual power options as well as the ability to upgrade your single leg power meter to dual leg, and introduced their fully customizable Dash cycle computer line.  They have also expanded their line of power meter to comprehensively cover the most popular cranksets in both road and mountain.  Ease of use, installation, accuracy and reliability make Stages our go to power meter choice.
