Product Details

Overview & Technology

SRAM Apex 1 brings 1x efficiency to road and gravel-adjacent riding with technology borrowed from SRAM's higher-end groupsets. The crankset pairs a patented X-Sync narrow/wide chainring profile with an integrated 4-arm asymmetric spider to deliver exceptional chain retention, stiffness and a strong stiffness-to-weight ratio in an all-aluminum package. Key engineering details include a 110 BCD, a 42-tooth X-Sync ring optimized for 10/11-speed drivetrains, a GXP interface with a 24/22mm spindle diameter, and a claimed crankset weight of 807g. The Apex 1 also offers 2mm more frame and tire clearance per side than many other road cranks, making it a practical choice for riders who run larger tires or ride frames with tighter clearances.

Key Features & Benefits

X-Sync chainring profile: The narrow/wide tooth geometry holds the chain securely on rough roads and off-road sections, reducing drops and allowing confident single-ring setups without a chain guide. Riders experience smoother chain engagement and reduced chain slap. Integrated asymmetric 4-arm spider: The spider is shaped to maximize lateral stiffness while keeping weight low, improving power transfer during hard efforts. The 45.5mm chainline is road-optimized and the 110 BCD allows aftermarket ring options if you want to swap sizes later. • Greater frame/tire clearance (+2mm per side) for wider rubber and mud-shedding. • Aluminum construction balances durability and weight for everyday use. • GXP spindle (24/22mm) for straightforward compatibility with SRAM road bottom brackets.

Fit, Installation & Compatibility

The Apex 1 uses SRAM's GXP interface and requires a compatible GXP bottom bracket (not included). The spindle steps from 24mm on the drive side to 22mm on the non-drive side, so choose a GXP BB sized for your frame's shell type and width. Chainline is 45.5mm and the crank is offered in 165, 170, 172.5 and 175mm arm lengths to suit most riders. SRAM rates this crankset for 10- and 11-speed 1x road systems. While it will work with many 10/11-speed chains, best results are achieved with SRAM chains matched to the X-Sync profile. Because the ring is 1x-optimized and the spider geometry is specific, the Apex 1 is not intended as a drop-in replacement for traditional double setups without careful planning.

Who It's For

Apex 1 suits road riders who want the simplicity and reliability of a 1x drivetrain—cyclists who prioritize fewer mechanicals, improved tire clearance, and robust chain retention for mixed-surface adventures or fast gravel detours. It's also a smart choice for commuters and endurance riders who value durability and a straightforward setup. If you're a lightweight-focused racer chasing every gram on graded road races and need a double chainset, Apex 1 may not be the ideal match. But for riders seeking a resilient, value-driven 1x crankset that handles wide tires and rougher roads, Apex 1 is a compelling, practical upgrade.

Frequently Asked Questions

Is the Apex 1 compatible with Shimano chains?

Yes — the Apex 1 ring will physically work with many 10- and 11-speed Shimano chains, but the X-Sync profile is optimized for SRAM chains. For best shifting and chain retention performance use a SRAM 10/11-speed chain or verify chain compatibility in your own setup.

Which bottom bracket do I need for the GXP spindle?

The Apex 1 uses SRAM's GXP interface (24/22mm spindle) and requires a GXP-compatible bottom bracket sized to your frame's shell width and type. Bottom brackets are not included, so choose a GXP road BB or adapter that matches your frame (road/BB86/BB30 shells need appropriate cups or adapters).

Can I convert this crankset to a double chainring?

No — Apex 1 is designed as a 1x solution. The chainring tooth profile and spider geometry are optimized for single-ring use and chain retention. While the 110 BCD means some aftermarket rings can be fitted, mixing in a second ring is not recommended for reliable shifting.

What crank arm lengths are available and how do I choose?

SRAM offers the Apex 1 in 165, 170, 172.5 and 175mm arm lengths. Choose length based on your leg length and pedaling style — shorter arms for higher cadence and agility, longer arms for leverage and seated power. If unsure, your current crank length is a safe starting point.

Is the bottom bracket included with the crankset?

No, the Apex 1 crankset is sold without a bottom bracket. You will need a GXP-compatible bottom bracket to install the crank (select the correct shell type and width for your frame).

How much extra tire clearance does Apex 1 provide?

SRAM specifies approximately 2mm additional clearance per side compared with many other road crank designs. In practice this helps accommodate wider tires and reduces the chance of chainring rub on frames with tight clearances, especially useful for gravel or mixed-surface road setups.

Buying Guide

When choosing a 1x road crankset prioritize chain retention, interface compatibility and chainline. Look for a proven narrow/wide profile like SRAM's X-Sync to prevent drops, and confirm the crank's spindle interface (GXP here) matches the bottom bracket you can install on your frame. Consider tooth count based on terrain: a 42T is a versatile middle ground for mixed road and light-gravel riding. Also weigh material and weight against durability — aluminum cranksets like Apex 1 offer solid longevity at a competitive weight and price. Finally, verify clearances for tire size and frame layout; Apex 1's extra 2mm per side can make the difference when running wider rubber or fitting tight frames.
