Product Details

Overview & Technology

SRAM Rival E1 1x Direct Mount chainrings are engineered as OEM replacement rings for Rival E1 single‑chainring cranksets. The ring uses SRAM’s narrow‑wide tooth profile and FlatTop chain compatibility to maximize chain retention and drivetrain efficiency on 1x gravel setups. The ring is precision‑machined from lightweight aluminium with a black hard‑anodized finish for corrosion resistance and long life. The Direct Mount SRAM 8‑bolt interface keeps the assembly simple and light while maintaining a secure connection to Rival E1 crank arms.

Key Features

Narrow‑wide tooth profile and SRAM FlatTop compatibility deliver confident chain retention and smoother engagement for 12/13‑speed drivetrains. This reduces chain drops and improves pedalling efficiency on rough gravel and mixed‑terrain rides. Available in 38, 40, 42, 44 and 46 teeth to tune gearing for climbing, speed or a balanced all‑round setup. The ring’s precision machining includes defined tooth geometry and optimized thickness for reliable shifting and low weight. • Direct Mount SRAM 8‑bolt interface for simple, secure installation • Hard‑anodized black finish for durability and corrosion resistance • Optimized for 12 and 13‑speed FlatTop chains

Fit & Compatibility

This ring is specifically designed as a replacement for SRAM Rival E1 cranks and is listed under SRAM Model ID: CR-XSNC-DM-E1. It uses SRAM’s direct‑mount 8‑bolt pattern and is compatible with 12‑ and 13‑speed SRAM FlatTop chains. Confirm your crank is the Rival E1 direct‑mount style before ordering. Not compatible with older 5‑bolt BCD or non‑SRAM direct‑mount spider standards. Installation follows standard direct‑mount procedures — reuse the original mounting hardware or use SRAM OEM bolts and torque to the crank manufacturer's specification. Chain length and derailleur setup may need minor adjustment when changing tooth counts.

Who It's For

Gravel and mixed‑terrain riders running a 1x Rival E1 drivetrain who need a durable, lightweight replacement ring will get the most value from this product. It’s ideal for riders who prioritize chain security, clean engagement, and a simple direct‑mount setup. Choose smaller tooth counts (38–40T) for steep, technical terrain and climbing efficiency; mid‑range sizes (42–44T) suit general gravel and all‑day rides; 46T favours higher‑speed or flatter routes. Racers, bikepackers and commuters who want a reliable SRAM‑spec ring will also find it a straightforward swap.

Frequently Asked Questions

Which cranksets will this ring fit?

This chainring is a direct replacement for SRAM Rival E1 direct‑mount crank arms (SRAM Model ID CR‑XSNC‑DM‑E1). It uses SRAM’s direct‑mount 8‑bolt interface and is intended for Rival E1 cranks — confirm your crank matches this mounting standard before purchase.

Is the ring compatible with 11‑speed chains?

The ring is designed and optimized for 12‑ and 13‑speed SRAM FlatTop chains. While an 11‑speed chain might physically fit, performance and chain retention are not guaranteed; for best results use the recommended 12/13‑speed chains.

Do I need new bolts or special tools to install it?

Installation uses the standard SRAM direct‑mount hardware. You can usually reuse the original bolts, but inspect them for wear and replace if necessary. No special tools beyond common crank/maintenance tools and the proper torque wrench are required; always follow SRAM’s torque specs.

Will changing tooth count affect my chain length?

Yes. Increasing tooth count often requires adding one or more links to the chain; decreasing might not require removal but should be checked. After a size change, verify drivetrain indexing and chain length, and test under load.

What material is the chainring made from?

SRAM machines these rings from lightweight aluminium with a hard‑anodized finish to resist abrasion and corrosion. The precise aluminium alloy and heat treatment are specified by SRAM for a balance of strength and weight.

Can I use this ring on non‑SRAM drivetrains?

Mechanically, the tooth profile will engage many compatible 12/13‑speed chains, but optimum performance is achieved with SRAM FlatTop chains and SRAM drivetrains. If mixing brands, expect variable shifting feel and retention characteristics.

Buying Guide

When choosing a replacement 1x chainring, match the ring to your crank’s mounting standard and intended terrain. Pick a tooth count that balances climbing ability and top‑end speed — smaller rings lower gearing for steep climbs, larger rings increase speed on flat sections. Always confirm speed compatibility; this ring is optimized for 12 and 13‑speed SRAM FlatTop chains. Consider material and finish for long‑term durability: anodized aluminium rings offer a strong, lightweight option for most riders. If you frequently ride rough gravel or carry heavy loads, choosing a narrow‑wide profile minimizes chain drops and reduces the need for additional chain guides.
