- Expandable Bladder
SRAM’s new brake lever design includes a reshaped bladder that helps regulate and reduce air bubbles. The bladder is specifically shaped to evacuate air from the lever and push the fluid exactly where it’s needed. The result is improved back-pressure relief, which produces dependable braking power and consistency.
- MatchMaker and MMX Compatible
Save weight and clutter on the bar with Matchmaker. It holds Avid levers, SRAM® triggers, and various RockShox® controls, all with one tidy, light, clamp--a dream come true for handlebar component footprint conservationists the world over. Available in two versions: Matchmaker™ X integrates the RockShox®XLoc and is compatible with XX and X0 brakes. Standard Matchmaker™is also available and works with any split-clamp design and RockShox® PushLoc.
- PiggyBack™ Reservoir
The brake fluid reservoir on SRAM’s latest lever design is optimized for both performance and ease of use. The PiggyBack Reservoir offers a simple, failsafe way to manage brake fluid, and also allows for ambidextrous lever placement—so you can switch your levers on the handlebar and run them moto without hassle.
- Reach Adjust
Brake lever fit and feel is a personal thing. Riders have individual positioning preferences, as well as unique hand sizes and finger lengths. Reach Adjust makes it easy to adjust your lever for maximum one-finger control for everyone.
Squeeze a new SRAM brake lever and you notice it immediately. Less deadband. More positive pad engagement. A new cam system requires less lever throw to push the pads toward the rotor. That’s great, but there’s more to perfect braking performance than just power. You need control. Many brake systems minimize deadband—but at the cost of modulation. SwingLink solves that with its special cam shape. When the pads contact the rotor, power is modulated, avoiding that “on/off” brake feel. It’s the perfect balance of power and precision.
- Timing Port Closure
A hydraulic brake’s timing port is the connection between the reservoir and the master cylinder bore. When the lever is squeezed, a cup seal passes this area and closes the port, which pressurizes the system. SRAM’s new timing port closure system features durable seals and an ultra-smooth cylinder bore finish, producing dependable braking power and consistency.

“The new Guide brakes offer improved consistency and more power over their predecessors, but haven’t sacrificed the impressive modulation that has always made the company’s brakes winners when it comes to low-traction scenarios. The bolstered reliability will be what wins the average rider over, though, as SRAM finally has a brake offering that I’d consider as being able to set-and-forget.“
