You now have an idea of what each disc brake will offer. Have you decided which brake to go for?

Even better, have you identified the differences between the two brakes? If you still haven’t, we will help you with that.

Here is a look at the major differences between the two-disc brakes:

Weight/Construction

There is no much difference between these brakes in terms of the construction.

Both of them come with sturdy aluminum parts for durability. You will not have to worry about rust or corrosion of the parts, thanks to the corrosion-resistant finish.

But the main difference comes in the weight. While the SRAM Guide R comes in at 392g, the Shimano SLX is heavier, with 198g at 590g.

Lever Material/Design

The lever material of both disc brakes is aluminum, but the difference comes in the design.

With the SRAM Guide R, you will get a DirectLink Lever that lets you enjoy a one-finger modulation.

On the other hand, the Shimano SLX disc brake comes with a SERVOWAVE lever that enhances the modulation ability of the lever.

The Shimano SLX brake also comes with a two-finger lever modulation.

Fluid Type

The fluid type of both disc brakes differ. With the SRAM Guide R brake, it uses the DOT 5.1 fluid. However, the Shimano SLX uses mineral oil as the brake fluid.

Both the disc brakes come with tool-less reach adjustment, and they have been designed to offer you easy and friendly handling while maximizing performance.

Keep in mind that the Shimano SLX disc brake comes at a higher price tag than the SRAM Guide R disc brake.

SRAM Guide R

The SRAM Guide R Hydraulic Disc Brake comes with a black gloss finish that helps to prevent it from catching rust or from common scratches as you ride your bike. It possesses a bleeding-edge design along with the new S4 caliper.

The new S4 Caliper and bleeding-edge design will update the brake fluid and bleed channeling to offer you easy brake maintenance.

Furthermore, you get a bleed adapter plug that protects the system from air and dust as you ride.

At only 392g, this disc brake is lighter than most models on the market. There’s also the Heat Shield technology that features stainless steel shields that will buffer the connection between the pad and the caliper body. This helps to reduce the heat transfer to the hydraulic fluid.

The disc brake features an aluminum DirectLink lever, and you can be sure of enjoying the tool-free adjustability of the lever.

Moreover, the brake also comes with a Timing Port Closure along with a sliding cup seal and port mechanisms.

These features let you enjoy an immediate actuation with the lever for one-finger modulation.

Furthermore, you get to choose either the front/left option or the rear/right option. You can use this disc brake with other SRAM’s centerline rotors.

In terms of the fluid, this disc brake uses DOT 5.1 fluid. Keep in mind that you will have to purchase the centerline rotors separately.

  • User-friendly operation
  • Regulates heat with the Heat Shield Technology
  • Works with other SRAM Centerline Rotors
  • Super-lightweight design
  • Bleed adapter plug protects the system from air and dust

CONS

What is Ice Tech?

Ice Technology is basically heat management technology.u003cbru003eu003cbru003eThis tech is built into specific models of Shimano brake rotors and pads. The technology helps to reduce heat build-up in the braking system.

How long will the brake pads last?

It depends on a few factors. If the disc brake pads are ridden where grit is not an issue, then they will last longer than those on a rim brake.u003cbru003eu003cbru003eSome disc brake pads can be ruined within a single wet, gritty ride, while others can serve you for two complete seasons.
