New gravel groupset takes inspiration from SRAM’s Transmission MTB components <\/p>

A new 13-speed SRAM Red XPLR AXS groupset has been spotted at the 2024 Unbound gravel race.\u00a0\u00a0<\/p>

When SRAM recently launched its flagship Red AXS groupset<\/a>, a gravel variant was curiously omitted.<\/p>

Now Red XPLR AXS is here \u2013 and it\u2019s a radically different product from its road counterpart.<\/p>

The new gravel groupset<\/a> borrows from SRAM\u2019s Transmission (what SRAM is officially referring to these components as, after initially being called T-Type) mountain bike groupsets, with the derailleur hanger incorporated into the rear derailleur itself, mounting directly onto a SRAM UDH<\/a> (Universal Derailleur Hanger) dropout.<\/p>

There are also some interesting features we didn\u2019t expect, which may give a hint about how SRAM\u2019s road and gravel groupsets will develop in the future.<\/p>

Let\u2019s take a look at the components.<\/p>

A direct-mount rear derailleur\u00a0<\/h2>

The new rear derailleur confirms it\u2019s a Red XPLR AXS model because it says so on the component \u2013 there\u2019s a \u2018Red\u2019 graphic on the main body and an \u2018XPLR\u2019 graphic on the derailleur cage by the lower pulley wheel.\u00a0\u00a0<\/p>

Like Red AXS, the Red XPLR AXS rear derailleur features handsome polished sections and appears to be equipped with ceramic bearings.<\/p>

The Red AXS rear derailleur relies on an Orbit Fluid damper, but the new derailleur appears to borrow the Overload clutch found on Transmission rear derailleurs.\u00a0<\/p>

The Overload clutch is focused more on protecting the derailleur\u2019s shift motor to better protect the derailleur from damage.\u00a0<\/p>

Unlike the new Red AXS rear derailleur, which relies on a conventional derailleur hanger, this Red XPLR AXS derailleur mounts directly to the frame\u2019s dropout.\u00a0<\/p>

This means the derailleur forgoes a conventional rear derailleur hanger and instead uses SRAM\u2019s UDH standard.<\/p>

Because of the UDH dropout, T-Type Transmission rear derailleurs lack limit and B-tension adjustment screws because the distance between the derailleur and cassette is controlled.\u00a0<\/p>

Instead, the derailleur is set up using SRAM\u2019s AXS smartphone app or via buttons on the derailleur itself.<\/p>

As a result of the rear derailleur lacking limit and B-tension screws, like Transmission, we suspect there will likely only be one cassette option.\u00a0<\/p>

In terms of ratios, the new 13-speed XPLR cassette could be a 10-48t, which would match Campagnolo Ekar GT \u2013 currently the widest-ranging gravel cassette offered by any of the Big Three groupset manufacturers.\u00a0<\/p>

By comparison, SRAM\u2019s Transmission rear derailleurs are designed around a single 10-52t cassette. The road-oriented SRAM Red AXS rear derailleur can handle up to a largest 36t cog.\u00a0<\/p>

Mountain bike uptake of the SRAM UDH dropout has been rapid and while it\u2019s becoming more widespread on gravel bikes<\/a>, there are many key models omitting the standard.\u00a0<\/p>

On the basis of this rear derailleur<\/a> relying on the standard, surely most, if not all new gravel bike releases are going to adopt the UDH standard, especially because the standard also plays nicely with competitors’ rear derailleurs.\u00a0<\/p>

Shared shifters and brakes\u00a0<\/h2>

Launched only a couple of weeks ago, SRAM Red AXS<\/a> is the brand\u2019s latest flagship road bike groupset<\/a>, shaving 154g from its previous generation.\u00a0<\/p>

SRAM Red AXS incorporates a new lever and hood design, improved braking performance and design, and faster front shifting. Other than the price, senior technical editor Warren Rossiter found little to fault in his review.\u00a0<\/p>

From what we can deduce, SRAM Red AXS XPLR shares many of the same components as Red AXS. The shifters, brake calipers and disc brake rotors appear to be identical.\u00a0<\/p>

The shifter’s new hood shape is much lower in profile compared to the previous generation and 7mm longer in reach, too. The hydraulic piston has also been reoriented from its previous vertical alignment to a new horizontal layout to improve braking performance.\u00a0<\/p>

Crankset<\/h2>
\"SRAM

The new crankset appears to be 1x only and the teeth are presumably oriented to mesh nicely with the chain.<\/p>

Over the weekend at Unbound, we\u2019ve seen a few riders using different crankset setups \u2013 Keegan Swenson\u2019s Santa Cruz Stigmata had a 1x aero chainring with an integrated power meter, for example, while others were using the existing, 12-speed Red 1 crankset with a non-integrated power meter.<\/p>

This suggests there may be some backwards compatibility between the new 13-speed components and existing 12-speed chainrings.<\/p>

We\u2019d nevertheless expect SRAM to release a new crankset with updated graphics and tooth profiles, though, as every new groupset needs a crankset, after all.<\/p>

Chain and cassette \u2013 a sign of the future?\u00a0<\/h2>
\"Santa
The fact Red XPLR AXS is 13-speed will almost certainly result in some product incompatibilities. – Brett Rothmeyer \/ Keegan Swenson<\/figcaption><\/figure>

One of the most exciting aspects of SRAM\u2019s latest Red AXS road groupset is its backwards compatibility. This means if you own a SRAM Apex, Rival or Force AXS groupset, you can upgrade to the new Red one piece at a time.\u00a0<\/p>

However, that doesn\u2019t seem to be the case with SRAM Red AXS XPLR. Why? Because it\u2019s 13-speed.\u00a0<\/p>

If you count the cassette cogs, there are 13 teeth. This is paired with a new 13-speed chain.<\/p>

The shifters, brakes and crankset may be borrowed from SRAM\u2019s flagship, 12-speed road groupset, but to upgrade here you\u2019ll likely at least need the new Red XPLR AXS rear derailleur, cassette and chain.<\/p>

\"Specialized

Previously, all of SRAM\u2019s performance-oriented road, gravel and mountain bike groupsets were 12-speed. This means they were all cross-compatible with one another, meaning, for example, you could pair road bike shifters with a mountain bike drivetrain.<\/p>

It makes sense for SRAM to go to 13-speed because, until now, this has been a key selling point for one of its main rivals, Campagnolo. Both its Ekar <\/a>and Ekar GT<\/a> groupsets are 13-speed and the extra cog enables a more progressive jump between gears.\u00a0\u00a0<\/p>

However, the downside is this means SRAM Red AXS XPLR will introduce more component incompatibilities \u2013 for example, you wouldn\u2019t be able to use a Transmission 10-52t cassette with the new rear derailleur if you wanted a wider gear ratio because it\u2019s 12-speed.<\/p>

This could mean a wholesale move to 13-speed groupsets is coming from SRAM in the future. However, T-Type Transmission is only the best part of a year old (and the new 12-speed Red AXS is just under three weeks old) and it wouldn\u2019t make sense for SRAM to supersede a product so soon into its lifecycle.\u00a0<\/p>

When will SRAM Red AXS XPLR be released?\u00a0<\/h2>

The groupset looks to be a final production unit rather than a prototype because of the production graphics, so a launch may not be too far away.\u00a0<\/p>

However, it appears to be one of the first times the groupset has been used out in the wild and there may be a period of SRAM gathering feedback from its sponsored professional riders, to check the performance stands up to real-world use.<\/p>

We\u2019ve asked SRAM to comment and will update this article when we receive a response.<\/p> <\/body><\/html>\n
