Brake testing
When Pinkbike, Vital MTB and ENDURO tested brakes head to head, they measured them with BrakeAce sensors.
All 33 articles“…some BrakeAce sensors… combining on-trail impressions with cold hard data.”
How BrakeAce works
Wireless brake sensors on your bike, plus an app that maps every brake to the trail. Record a run, review your braking on a trail map, compare the next one — that's the loop.
Metrics
What gets measured
On every run the brake sensors record these signals on both brakes. The app turns them into your trail map and Key Opportunities; the web dashboard lets you dig into the detail.
Braking intensity
How hard you brake at every moment — the force behind each front and rear brake.
Duration
How long each brake lasts, from a fleeting tap to a long, dragging hold.
Location
Exactly where on the trail each brake happens, mapped point by point.
Temperature
Brake temperature through the ride — spot fade before it costs you control.
Modulation
How smoothly you apply and release — the difference between grabbing and finessing.
Front / rear balance
How you split braking between front and rear, corner by corner.

Fit the brake sensors
The brake sensors replace the 20 mm spacer between your frame and brake caliper, front and rear. Standard post-mount calipers on most modern MTBs. Most riders are recording within minutes.
