Product Details

Overview & Technology

SRAM Red B2 53T (CR-XGLD-130-A1) is an 11-speed outer chainring engineered to visually and mechanically match Red and Red Quarq B2 (eTap) cranksets. Built in a 130mm 5‑bolt BCD format, this 53-tooth ring provides a classic road racing gear for high-speed efforts and sustained pace riding. The ring is constructed from lightweight aluminum with a precision-machined profile and a durable black finish to complement SRAM's Red crank graphics. Although it does not use a narrow-wide tooth profile, the tooth geometry is profiled for reliable 11-speed shifting and responsive chain engagement under load.

Key Features & Benefits

Core specifications: 53 teeth, 130 BCD, 5-bolt pattern, outer position, 11-speed optimized. The model ID is CR-XGLD-130-A1 and the factory finish is a black anodized-style surface to match Red/Quarq aesthetics. • Lightweight aluminum construction delivers a stiff, responsive drive feel while keeping rotational mass low. • Precision-machined tooth profile ensures consistent 11-speed shifting performance across road conditions. • 5-bolt 130 BCD standard allows straightforward replacement on cranksets using that bolt-circle diameter.

Fit, Compatibility & Installation

This chainring is designed as an outer ring for 5-bolt 130mm BCD cranksets and is intended for 11-speed drivetrains. It pairs naturally with a 39T inner ring in common 53/39 crankset combinations, but will also fit any crank arm spider using the 130 BCD 5-bolt pattern. Because the ring is not narrow-wide, it relies on proper chainline and a correctly adjusted front derailleur for optimal performance. Always use compatible chainring bolts and follow your crank/bolt manufacturer's torque and installation recommendations. Check chain length and front derailleur limits when switching to a 53T outer ring.

Who This Chainring Is For

Targeted at road racers, crit riders, and fast group-ride cyclists who want a 53T top-end gear and a perfect visual match to SRAM Red / Red Quarq B2 cranks. It's ideal when you need a direct replacement that retains OEM appearance and 11-speed shift feel. Not intended as a mixed-terrain or single-ring narrow-wide conversion — if you ride gravel or mixed surfaces and prioritize chain retention, consider narrow-wide or dedicated chain retention options instead.

Frequently Asked Questions

Will this fit my crankset?

The Red B2 53T uses a 130mm 5-bolt BCD, so it will fit crank spiders that use that standard. Confirm your crank's bolt-circle diameter and 5-bolt pattern before ordering.

Is this chainring compatible with 10- or 12-speed drivetrains?

This ring is optimized for 11-speed chains and shifting geometry. It may physically fit other speeds, but for best shifting and wear characteristics use it with an 11-speed drivetrain.

Can I use this as an inner ring or on a double/compact setup?

This is specifically an outer chainring (53T). It is intended to pair with an appropriate inner ring (commonly 39T for 53/39 setups). It is not designed to be used as an inner ring.

Does the ring include chainring bolts?

Chainring bolts are not listed with the product. Use compatible 5-bolt chainring bolts of the correct length for your crank spider and chainring stack height.

How durable is the finish and material?

The ring is made from aluminum with a durable black finish to match SRAM graphics. Aluminum provides a good stiffness-to-weight ratio; normal wear will occur over time depending on riding conditions and maintenance.

I have a Red Quarq power meter — will this match visually?

Yes. The Red B2 black finish is produced to match the Red and Red Quarq B2 crank graphics for a cohesive look when installed alongside Quarq power meter-equipped cranks.

Buying Guide

When choosing a road chainring, first confirm bolt-circle diameter (BCD), bolt count and target drivetrain speed. For SRAM Red B2 53T, you need a 130mm 5-bolt crank spider and an 11-speed chain for the best shifting performance. Match your outer ring size to the inner ring and your front derailleur capacity to avoid chain rub and ensure correct chain length. Material and tooth profile affect weight, stiffness and shifting feel. Aluminum rings like this offer excellent stiffness-to-weight balance and a clean aesthetic match to OEM cranks. If you ride mixed surfaces or need extra chain security, consider narrow-wide profiles or dedicated chain retention hardware instead.
