Drivetrain Telemetry
Find your drivetrain sweet spot
Huge TT chainrings are not just for show. At high speeds, larger chainrings can help riders stay on more efficient rear sprockets, improve chainline, and reduce drivetrain losses.
But the fastest chainring is not always the biggest one — it is the one that matches your speed, cadence, cassette, terrain, and real gear usage.
DrivetrainStats helps you find that sweet spot from your own ride data.
