Sram GXP MTB crankset

GXP crankset: SRAM's take on MTB drivetrain performance

In the demanding world of mountain biking, every component plays a vital role in performance and reliability. The GXP crankset from SRAM follows this philosophy, offering a robust, precise solution that fits a wide range of setups. Let’s take a closer look at this key part of the MTB drivetrain, often overlooked but essential for optimal power transmission.

What is the GXP crankset ?

The GXP (Giga X Pipe) crankset is a technology developed by SRAM, designed around an integrated crank spindle that maximizes power transfer. Commonly found on many MTB setups, the system includes:

• a 24 mm spindle attached to the right crankarm,

• a GXP bottom bracket,

• and crankarms made of aluminum or carbon, depending on the model.

Together, they form a lightweight, stiff and durable unit designed for efficient pedaling, even on the roughest trails.

GXP crankset technical features

The GXP crankset stands out for several technical features that make it a popular choice among mountain bikers:

1. Asymmetrical spindle design

The GXP system uses a spindle fixed only on the drive-side crankarm. The non-drive-side bearing is free-floating, which helps distribute load more evenly and reduces stress on the bottom bracket. The result: less wear and easier maintenance.

2. Wide compatibility

The GXP crankset is compatible with:

• BSA threaded bottom brackets (68/73 mm),

• PressFit GXP bottom brackets (86.5/89.5/92 mm),

• and 1x, 2x, or 3x chainring setups.

This makes it suitable for many riding styles: cross-country, trail, all-mountain, or enduro.

3. Smooth drivetrain performance

When paired with a SRAM chain and 10, 11, or 12-speed cassette, the GXP crankset ensures crisp, reliable gear shifts. Its lateral stiffness provides excellent responsiveness under hard pedaling, whether you're climbing or accelerating.

4. User-friendly maintenance

Removing a GXP crankset is straightforward: only one tool is needed to extract the crankarm. The GXP bottom bracket features sealed bearings, offering long-lasting performance even in wet or muddy riding conditions.

Advantages of the GXP crankset for MTB

Choosing a GXP crankset means benefiting from:

• a durable and efficient drivetrain,

• easy installation and removal,

• broad frame compatibility,

• and a great value for money, especially on SRAM X5, X7, X9 or GX groupsets.

Whether you ride a 1x setup for enduro or double chainrings for XC, the GXP crankset adapts to your needs while ensuring consistent power transfer to the rear cassette.

In summary

The SRAM GXP crankset remains a solid choice for riders seeking reliability, smooth performance, and versatility in their MTB drivetrain. Thanks to its smart design and proven durability, it continues to appeal to everyone from weekend riders to competitive racers. Definitely a component to consider for your next bike upgrade !
