Hayes Stroker Ace Hydraulic Brake

The Stroker Ace features Hayes' first four-piston, forged mono-bloc caliper and our biggest pads ever, giving the Ace tremendous heat management capabilities. We've also designed a longer lever for increased leverage at the bar. Mated to the proven Stroker master cylinder, this makes the Ace our most powerful brake ever, while advancing the already unmatched Stroker modulation. At a system weight of 427g (including 6" rotor and hardware), the Ace trumps all the other gravity-oriented brakes in the deck.

THE STROKER IN DEPTH

The Radial Design
Close-Pack Construction (CPC) results in zero wasted space. Every element of this radial master cylinder is optimized for strength, light weight and compact size.

Lever Design
The perfect lever design disappears in your hand. An internal lever team used bench-marking, Hayes test program feedback, CMM scanning and finite element analysis, all to make a lever that you won't even notice.
CMM - Coordinate Measuring Machine

Aluminum Adjuster Dial
The Aluminum adjuster dial uses a sping detent for reach adjustmet with positive clicks. Oversized metal bushings surround the dial yielding smooth actuation and durability.

The Caliper
The Stroker's insulated caliper pistons control fluid temperature during heavy braking, so every braking stroke engagesthe caliper smoothly and consistently, eliminating lever fluctuation and providing a reliable feel.

Hayes' largest brake pads to date result in optimal heat management and deliver loads of power.

Adjustable hose routing on all calipers to set the ideal has exit angles on any bike.
