SRAM Rival 1 GXP Crankset Info
The SRAM Rival 1 GXP Crankset is a dedicated 1x road crankset built for riders who want to run a clean, single-ring drivetrain without stepping up to Force or Red. It sits in the middle of SRAM's road hierarchy — more capable than Apex, more accessible than the higher tiers — and brings SRAM's proven 1x drivetrain philosophy to everyday training rides, sportives, and gravel-adjacent road builds.
The GXP (Giga X Pipe) spindle interface is SRAM's long-standing standard, offering broad compatibility with GXP-threaded bottom brackets and a well-tested, reliable connection between crank and frame. The crankset is available in both 42t and 50t chainring options, covering riders who want a compact setup for climbing-heavy routes or a larger ring for faster terrain. Three crank arm lengths — 170mm, 172.5mm, and 175mm — mean you can dial in fit without compromise. The narrow-wide chainring tooth profile is designed to improve chain retention, keeping the drivetrain engaged even without a chain guide on most road and light mixed-surface setups.

Design Benefits
- Simplified drivetrain, reduced weight: Removing the front derailleur, shifter, and second chainring cuts clutter from the cockpit and reduces overall system weight — a practical advantage on long days where every gram and every distraction adds up.
- Chainring choice to match your riding: The 42t option suits riders tackling hilly courses or mixed terrain where a lower gear range is a genuine asset. The 50t suits flatter routes and riders who push higher cadences and want to stay in the chainring without spinning out.
- Broad fit compatibility: Three crank arm lengths give you real options for dialing in biomechanics, whether you're optimizing for a road race position or building a more relaxed endurance setup.
