SRAM Apex 1 10/11-Speed 1x 42T 110 BCD GXP Crankset

The SRAM Apex 1 is a 10/11-speed single-ring crankset on the SRAM/Truvativ GXP spindle interface, supplied with a 42T X-SYNC chainring. SRAM positions it as an affordable way to get the features that made its 1x road cranks popular: X-SYNC chain control and generous tire and frame clearance.

It's offered in 165, 170, 172.5 and 175mm arm lengths, all with the 42T ring. The integrated 4-arm asymmetric spider uses 110 BCD, so you can change ring size later. The bottom bracket is not included.

Who It's For

• Cyclocross, gravel and road riders running SRAM 10- or 11-speed 1x
• Riders on GXP-compatible frames who want a simple 1x crank
• Builders who want a 110 BCD spider for future ring changes
• Consider a different crank if your bike uses a DUB bottom bracket or a 12-speed drivetrain

What to Look For

• Spindle interface: SRAM/Truvativ GXP — needs a GXP bottom bracket (sold separately). It does not fit DUB bottom brackets.
• Ring and BCD: 42T X-SYNC on a 110 SRAM asymmetric 4-arm spider; 10/11-speed.
• Crank length: choose 165, 170, 172.5 or 175mm.

Key Features

Integrated 4-arm asymmetric spider. SRAM says the spider design maximizes stiffness-to-weight. For riders, 110 BCD means a wide choice of replacement 1x rings.

X-SYNC chainring. The included 42T ring uses SRAM's X-SYNC wide-narrow profile to control the chain on a 1x drivetrain without a front derailleur — helpful on rough cyclocross and gravel courses.

GXP spindle. The GXP interface pairs with GXP bottom brackets, which come in versions for many frame shells. Matching the BB to your frame is the key fitment step.

Clearance and Q-factor. SRAM cites above-average tire and frame clearance, and the Q-factor is 149mm.

Four lengths, black. 165 to 175mm in black, with 9/16" pedal threads.

Rider Intent Summary

• Biggest strengths: X-SYNC 1x chain control, a 110 BCD spider for ring changes, and four arm lengths.
• Tradeoffs: GXP only (not DUB), 10/11-speed only, and the bottom bracket is extra.
• What makes it different: It's SRAM's entry-level 1x road and cyclocross crank, with a 110 BCD spider rather than direct-mount rings.

Victory's Take

We'd use the Apex 1 to refresh a GXP-based 10/11-speed cross or gravel bike, and Victory Bicycle Studio will confirm the GXP bottom bracket for your frame.
