The wireless groupset comes with many wholesale changes. In fact, it’s a completely new concept for a groupset which SRAM
SRAM’s AXS (pronounced access) is a new bike component integration system which allows you to see battery status, change component behavior, personalize controls, get maintenance reminders, and update firmware via the AXS app on your smartphone. The
The Shift-Brake System
Naturally, it’s a fully wireless electronic shifting system and a hydraulic disc brake setup. What’s more, the brake levers can be customized to suit your hand size and reach with a contact point adjust and reach adjust. Textured shift paddles and hoods provide a better feel and are safer. Shifting sequences can be personalized too.
With space carved out to increase clearance and allow for wider rear
As is with almost every other piece of the SRAM AXS puzzle the rear derailleur is personalizable. It’s a single rear derailleur which works with both the 1x or 2x system and it incorporates a chain management technology called Orbit which keeps the drivetrain quiet and secure across all terrain types. The derailleur also features faster pulleys, bearings, motors
The new chain features a unique link shape with a flat top which increases strength despite being thinner and lighter. A larger space between the outer plates of the chain and the cogs helps create a quieter ride with more precise shifts. Hard Chrome plated inner link plates and rollers reduce wear whilst the Hollow Pin construction improves strength and efficiency.
The 12-speed cassette has a wider range of gears and is specifically designed for wireless electronic shifting. Available in either a 10-26, 10-28 or 10-33 spread, the one-piece construction saves weight and an updated design yields smoother and faster shifting. A more gradual gear progression between cogs with at least five one-tooth jumps and a 10-tooth cog which gives an overall wider range.
Smaller Chain Rings
The 2x chainring combinations are available in a 46/33, 48/35 and a 50/37. The 1x chainring comes in a 36 tooth up to a 46 tooth option with bigger sizes available for TT or Tri usage.
SRAM integrated a Quarq DZero power meter directly into the RED chainrings to reduce weight and improve on accuracy. The power meter is equipped with 10K multipoint active temperature compensation and an IPX7 waterproof rating for accuracy and consistency in any weather conditions.
SRAM says the power meter-equipped chainrings last 50% longer than their previous generation and they offer a
The power readings are accurate to within +/-1.5% and
The DUB bottom bracket technology cleans up the product line and makes it easier to choose the right model for your bike.
In certain disciplines, the single-ring drivetrain reigns supreme by way of simplicity, strength, and durability so SRAM offers the RED 1x AXS™ to meet these demands. The power meter features improved aerodynamics thanks to direct mount aero chainrings and the tighter gearing range is perfect for racing in areas with flatter terrain. Interestingly the chainrings can be swopped out for a different size without requiring a recalibration of the power meter.
Of course, you don’t have to ride disc brakes to experience the benefits of AXS as SRAM have included a mechanical rim brake option in the range.
