The All-New SRAM RED

This generation of SRAM RED didn’t just see a minor tweak, it saw a complete overhaul. That means new brakes, shifters, cranks, cassettes, and front and rear derailleurs. The latest iteration features a new lighter brake feel, better ergonomics, better shifting, and expanded gear ranges, on top of all that it’s the lightest electronic groupset out there.

Front Derailleur

A re-designed front derailleur offers faster, smoother, and more accurate shifts than its predecessor. The SRAM RED AXS front derailleur now features an automatic trim adjustment, this means a silent ride with no chain rub. To make life easy on the mechanics out there a new adjustment tool has been designed to make setup quick and easy.

Rear Derailleur

The rear derailleur got a face lift as well. Gone are days of multiple cage lengths, the new SRAM RED AXS rear mech now accommodates the full range of SRAM road cassettes from 10-28T up to 10-36T. The pulley wheel size has also seen a bump up in size, this decreases the chain angles around the pulleys and increases the efficiency of the system. The rear derailleur also features SRAM’s Orbit fluid damper to keep things in place and quiet while on the rougher roads. All while being 16g lighter than before.

Chain and Cassette

Acknowledging that riders want more range, SRAM has improved the range XG-1290 cassette with new RED. There are 2 new options joining the XG-1290 line, a 10-30T profile for people looking for a bit of extra range on race day and a 10-36T for those big elevation days. The new HollowPin construction is lighter and stronger than solid pin designs. The cutouts in the new chain aren’t just for looks, overall they shed 13g of weight from the chain compared to the previous RED chain. Overall, the new RED chain is lighter, stronger, and more durable than before.

Cranks and Powermeters

Nothing was left untouched in the RED line, the crankset has a new hollow carbon construction that’s 16g lights. When combined with the one piece chainrings, the latest version is also stiffer than the previous generation. There are three chainring combinations available to suit every rider's needs, you can choose from 50/37T, 48/35T, and 46/33T or if you want 1x there is a 50T chainring option. To help get the right fit a 160mm crank length has been added, this joins the existing 167.5, 170, 172.5, and 175mm options. If you’re looking to track your wattage during your ride, there are power meter options available in all lengths and chainring combos.


You better believe there’s a new rotor to go with the new RED groupset. The new Paceline X Rotor has a nice quiet braking surface, while the new aluminum carrier helps lighten the rotor while keeping it cool under braking. The new Paceline X rotors are available in both 160mm and 140mm sizes.
