Product Details

Overview & Technology

SRAM Rival1 brings a purpose-built, single-ring approach to road and track drivetrains with a forged aluminum construction that balances stiffness and weight. The crankset ships with an X‑Sync chainring (42T in this variant) that is engineered for positive tooth engagement and improved chain retention—ideal for aggressive pedaling and clean shifting under load. The Rival1 uses a GXP interface with a 24/22mm crank spindle diameter and a 45.5mm chainline, making it compatible with common road bottom bracket standards via the appropriate GXP cups. At approximately 799g, it offers a competitive stiffness-to-weight ratio for riders prioritizing responsiveness without the premium price of carbon options.

Key Features

Materials & construction: Forged aluminum crank arms provide durability and predictable flex characteristics. The X‑Sync chainring is designed with narrow/wide tooth profiles to reduce drops and improve chain security on 1x setups. • BCD: 110mm — gives options for chainring swaps and upgrades. • Interface: GXP spindle (24/22mm) — fits GXP bottom brackets (not included). • Teeth / Options: 42T standard (also available in 50T or other variants), single-ring optimized. • Pedal thread: Standard 9/16" spindle thread across variants.

Fit & Compatibility

The Rival1 is compatible with SRAM 10- and 11-speed drivetrains and is designed around a 45.5mm chainline for road spacing. Choose the crank arm length (170mm, 172.5mm, 175mm) and chainring size that best match your riding style and cadence. Bottom brackets are not included—select a GXP-compatible BB for threaded shells or choose the BB30-specific Rival1 variant if your frame uses BB30 bearings. Because the spindle uses the GXP 24/22mm stepped diameter, installation requires the correct GXP cups (or the BB30 variant for frames with pressed bearings). The 110 BCD offers flexibility for changing chainrings, but the crankset is optimized for single-ring (1x) setups with X‑Sync ring geometry for best chain retention and shifting behavior.

Who It's For

The Rival1 is aimed at road riders who want the simplicity and chain security of a 1x drivetrain without sacrificing stiffness or durability. It's an excellent choice for daily road training, cyclocross racers moving to a single-ring setup, and riders upgrading an alloy crank for a lighter, more responsive feel. Choose Rival1 if you value a maintenance-friendly, reliable crank that performs under sprinting and climbing loads but don’t need the price or fragility of a full carbon race crank. If you ride frames with BB30, select the BB30 variant to avoid adapters.

Frequently Asked Questions

Is the bottom bracket included with the Rival1 crankset?

No. The Rival1 crankset is sold without a bottom bracket. For the GXP spindle variants, you will need a GXP-compatible bottom bracket (threaded or press-fit adapters depending on your frame). If your frame uses BB30 bearings, consider the BB30-specific Rival1 variant.

Can I use this crankset with a 2x (double) chainring setup?

The Rival1 is optimized for 1x setups and ships with an X‑Sync single chainring. While the 110 BCD allows some flexibility with chainrings, traditional 2x shifting may require compatible chainrings, spacers and a front derailleur; for reliable 2x performance we recommend selecting a crankset specifically designed for double-ring drivetrains.

Which chain speeds is this crank compatible with?

This crankset is compatible with SRAM 10- and 11-speed chains. The supplied X‑Sync ring is profiled for modern narrow/wide chain engagement to work best with 11-speed chains, but it will also work with 10-speed SRAM chains.

What bottom bracket do I need for a GXP Rival1 crank?

For GXP Rival1 variants choose a GXP bottom bracket that matches your frame shell (e.g., BSA 68/73). GXP cups are widely available; follow SRAM's installation instructions for preloading and torque settings. If your frame is BB30, pick the Rival1 BB30 variant or use the correct adapter kit.

Are other chainring sizes available?

Yes. Rival1 is offered in multiple chainring sizes including 42T and 50T depending on the variant. The 110 BCD also allows you to swap in aftermarket chainrings compatible with that BCD to tailor gearing to your riding.

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

Rival1 comes in 170mm, 172.5mm and 175mm lengths. Choose shorter arms for higher cadence and lighter riders or longer arms for leverage and taller riders. If unsure, match the crank length to your current setup or consult a bike fit professional for optimal leg extension and knee comfort.

Buying Guide

When choosing a road crankset, consider three main factors: crank arm length, chainring size, and bottom bracket compatibility. Crank lengths (170–175mm) affect leverage and knee angles—shorter arms favor cadence and clearance, while longer arms give more torque. Select a chainring that suits your terrain: mid-sized rings (40–42T) for mixed climbing and flats, larger rings (50T) for high-speed road use. Verify your frame's bottom bracket standard before ordering. The Rival1 GXP variants need a GXP-compatible BB; if your frame uses BB30, order the BB30-specific Rival1 variant or the correct adapter. Finally, decide if you want the simplicity of 1x (better chain retention and less clutter) or a 2x setup (wider gearing range)—Rival1 is optimized for 1x applications with X‑Sync chainrings.
