03 Crank it up
Full-alloy crank arms attach to a DUB axle with a direct-mount chainring, the same as Rival’s chainset
Could SRAM’s expansion of AXS (the wireless integration system that connects electronic bicycle components) all the way down to Apex, the lowest in its groupset hierarchy, bring the advantages of electronic shifting to more price-conscious riders? We find out.
My test set-up is the gravel-friendly, 12-speed Apex AXS XPLR groupset (below Rival, Force and Red), with the optional-upgrade power meter and new 11-44-tooth cassette matched to a 40t chainring. The AXS electronic levers control both gears and brakes and the AXS XPLR electronic rear derailleur helps you shift smoothly across the larger cassette. Apex AXS has a claimed complete weight of 2,900g (just 50g less than Rival AXS) and SRAM claims complete bikes sporting the new groupset should cost from around £2,500.
Apex shifters are basically the same as on Rival AXS, and the same profile as the latest Force AXS lever, but are made from pressed alloy rather than Rival’s forged alloy or Force’s carbon. However, they feel much the same, with an indented shape and textured surface. You can even alter the reach via a 2.5mm hex bolt on the hood. The simplicity of SRAM’s shift logic is perfect for 1x gravel systems, the right-hand trigger putting you into a harder gear and the left into an easier cog. I also used SRAM’s wireless blips on the underside of my bar tops to shift on climbs to save reaching for the hoods.
The system connected quickly and easily to both my Hammerhead Karo 2 head unit and the AXS app on my iPhone, giving gear, power and battery information, and the app records shifts, power and the usual GPS data. The levers also work well with the new brake design. The flat-mount-compatible brake units follow the same design as the latest Force AXS brakes. Performance and feel were very familiar, and there was no rotor scrape.

The chainset is also basically a carryover from Rival, with full-alloy crank arms attached to a DUB axle with a direct-mount chainring. The nicely machined teeth in SRAM’s narrow-wide chainring pattern held onto the chain really well. The matte finish may not look as premium as Rival’s gloss, but the single-sided meter’s power readings are consistent with my double-sided Force and Red level meters on my own bikes.
The derailleur’s compact body is also taken from Rival AXS and the XPLR cage means a capacity of up to 44 teeth for the new Shimano HG-compatible 11-44 cassette. It shifted smoothly and quietly, and the spring-loaded clutch does a superb job of keeping chain bounce in check, even on rutted singletrack. You still get SRAM’s flat-topped chain design, but here it’s a simple polished steel in a grey finish. The chain kept in harmony with the ring and cassette though.
I can’t notice any difference in shift speed, chain control or braking feel between Apex and Rival. It’s mainly down to material choices and finish, which add a few grams. While weight’s not a huge issue for me when gravel riding, longevity is, and that remains to be seen. But, if I did want to upgrade later on, SRAM’s compatibility between ranges means that’s an option.
The Good
Sweet shifting; improved lever ergonomics; full-feature groupset
The Bad
Grey chain looks unfinished compared to the rest of the group; 1x only
Also consider…
Shimano GRX Di2 | £2,065
● Shimano’s GRX Di2 can be found in 1x or 2x configurations, but unlike its road-going Di2 cousins, it remains fully wired and 11 speed. However, rumours are rife of an imminent 12-speed update, which, if true, could mean that there will be plenty of discounted 11 -speed components out there soon. Exemplary braking and slick shifting mark GRX Di2 as a great off-road group.
SRAM Rival AXS | £1,700
● If you want wireless AXS shifting and a 2x drivetrain (for a wider gear range and smaller jumps between gears), then Rival AXS offers a clutch-equipped rear mech that can handle gravel (helping avoid chain slap or worse), and a myriad of gearing options too. Or you can opt for the gravel-specific XPLR version for a wider rear cassette and single-ring chainsets.
