Product Details

Overview & Technology

SRAM's 34T 2x10 chainring is a purpose-built outer ring for traditional 2x10 mountain drivetrains. Made from machined aluminum with a Blast Black AL5 finish, it balances low weight and long-term durability while matching the tooth profile expected by 10-speed chains. This ring uses a 104mm BCD with four bolt holes and a medium pin/ramp arrangement on the outer position to help guide the chain during upshifts to the larger sprocket. It isn't a narrow-wide design and is optimized for double-ring shifting rather than single-ring chain retention.

Key Features

Built for reliable shifting and longevity. The ring's aluminum construction keeps weight down (manufacturer weight ≈ 0.1 lb) while the Blast Black finish offers corrosion resistance and a clean factory look that matches many SRAM drivetrains. • 34 teeth — comfortable climbing and mixed-terrain gearing for MTB rides. • 104 BCD, 4-bolt — compatible with a wide range of cranks that use the 104 bolt-circle diameter. • Medium pin/ramp profiles — engineered to improve upshift speed and precision in 2x setups. • 10-speed specific tooth profile — optimized chain engagement for reliable performance on 10-speed chains.

Fit & Compatibility

This chainring fits cranks that accept a 104mm BCD, 4-bolt outer ring and is explicitly intended as an outer ring in 2x10 configurations. It works with 10-speed chains and typical SRAM/Shimano 2x front shifting systems when paired with the correct inner ring and front derailleur setup. Note that it is not a narrow-wide chainring — do not expect single-ring chain retention performance if you convert to 1x. Always verify crank bolt torque specifications, ring tooth orientation, and that the ring's ramps/pins align with your inner ring for best shifting results.

Who It's For

This SRAM 34T outer ring is ideal for riders restoring or upgrading 2x10 mountain bikes, racers who want a lightweight replacement outer ring, and cyclists who prefer the gear spread of a 34-tooth outer on mixed-terrain rides. It's also a good choice for owners of older bikes that still use 10-speed drivetrains and 104 BCD cranks. If you've converted to 1x or run 11/12-speed drivetrains, look for a narrow-wide or speed-specific chainring instead — this ring is tailored for classic 2x10 performance and compatibility.

Frequently Asked Questions

Will this ring fit my crank?

This ring fits cranks that accept a 104mm BCD with four bolts and an outer-position chainring. Check your crank's bolt circle diameter and bolt count before purchase. If your crank uses a different BCD or an integrated spider with non-standard ring mounting, this ring will not fit.

Can I use this chainring for a 1x conversion?

No — this is not a narrow-wide chainring and lacks the alternating thick/thin tooth profile used for 1x chain retention. While it will physically fit on a 104 BCD crank, you should use a dedicated narrow-wide ring for reliable single-ring chain retention.

Is this compatible with 11- or 12-speed chains?

This ring is specifically profiled for 10-speed chains. Using wider 11- or 12-speed chains may result in suboptimal shifting and engagement. For 11/12-speed drivetrains, choose a ring designed for those speeds.

What tools and torque do I need to install it?

Installation requires a compatible hex/torx key or chainring bolt tool for your crank's bolts and a torque wrench to meet manufacturer torque specs. Always follow your crank maker's recommended bolt torque and tightening pattern to avoid damage or loosening.

How durable is the finish and material?

The ring is machined from aluminum and finished in Blast Black (AL5), offering a good balance of light weight and corrosion resistance. With normal use and proper installation, it provides long service life; avoid harsh impacts and inspect often for bent teeth after crashes.

Can I mix this with an aftermarket inner ring?

Yes, you can mix with compatible inner rings provided the inner ring matches the 2x10 ramp/pin design and the combined tooth counts yield proper chainline and shifting. For best shifting performance, pair with rings designed to work together or OEM-recommended inner rings.

Buying Guide

When choosing a replacement chainring for a 2x10 MTB, prioritize correct BCD, tooth count, and speed compatibility. The 104mm BCD is one of the most common standards for mountain cranks — verifying this and the bolt count will ensure a direct fit. Consider tooth count in relation to your cassette and riding style: a 34T outer ring offers a comfortable balance between climbing ability and top-end speed for mixed-terrain riding. Also match speed-specific profiles (10-speed here) and ramp/pin designs for the best front shifting performance.
