DT SWISS have nigh on reinvented their popular 1501 SPLINE ONE wheelsets, upgrading the whole range to carbon rims with lighter Race-spec spokes hooked up to DT’s new 240 hubset.

From XC to Enduro, DT have opted for a 30 mm internal and 36 mm external rim width across the entire line-up. Despite this, each rim offers progressively larger impact resistance as we look up the line, with the enduro wheelset offering the greatest impact resistance. Let’s take a closer look.

The new 1501 SPLINE ONE range from DT SWISS covers XC, All-Mountain and enduro mountain biking disciplines, each wheelset optimized for performance according to that discipline’s requirements.

That said, all three wheelsets offer an internal rim width of 30 mm. Wider rims have long been increasing in popularity, now the most common rim width found on the enduro race track, and fast becoming very popular in cross-country racing too.

The major update for the 1501 SPLINE ONE Wheelsets is the fact that they now use carbon, as opposed to aluminium rims. DT’s reasoning for this change is simple; carbon rims are lighter. And stiffer.

The increased stiffness of the new carbon rims has also meant that DT were able to spec the wheelsets with their ultra-lightweight Competition Race spokes. Each wheelset features 28 straight-pull double-butted spokes laced in a 3-cross pattern (1:1).

Each spoke has a middle section 0.2 mm thinner than the previous Competition spokes. As a result, along with weight savings elsewhere, DT SWISS have been able to save up to 180 g on the new wheelsets, as compared to their alluminium predecessors.

All three 1501 SPLINE ONE wheelsets are also upgraded to DT’s new 240 hubset with its 36T Ratchet EXP internals offering 10° engagement. The new hubset is lighter than the previous 240s – around 50 g less on the front and another 30 g lighter on the rear. This is mainly due to the reduced number of parts – seven instead of the original five ratchet components of the 240s. That, and the more precise machining of these alloy hub shells.

XRC Cross-Country 1501 SPLINE ONE

DT’s new XRC 1501 SPLINE ONE wheelset for cross-country mountain biking gets wider rims for 2021. Internal width now measures in at 30 mm, substantially wider than the 22.5 mm and 25 mm internal rim widths offered by the previous (aluminium) generation.

DT cite one major reason for the upgrade to wider rims – a wider rim provides improved tyre support, allowing riders to run lower pressures. This in turn results in reduced rolling resistance over rough terrain as the tyre isn’t forced to move up and over the small stuff – rather the tyre can adapt to the shape of the terrain and track more efficiently.

  1. After the entire industry figured out wider is better like more than a decade ago DT finally comes correct. [slow golf clap]

    • 1501 has had options from 22.5-40mm wide since at least 2015, and was amongst the first to de-couple the idea of wider=heavier duty. The new 1501 width represents a step backwards (fewer width choices) than previous. Just because you weren’t paying attention doesn’t mean they weren’t.

  2. Tyler, please make a rule for any press releases to NEVER post a companies graph of “awesomeness” for something with no units/scale on the Y-axis. That impact energy graph is completely worthless.

  3. Very cool, I’ve always thought that dt wheelset were underrated. A little expensive aftermarket but a great score if they come on the bike.

    Buuut, after less than a year the EXP 180 hubs on my trail bike have started skipping, sometimes noisily taking popping like a 3-pawl before engaging. Has anyone else had the same problem? Hopefully the 240 is to 180 is like XT to XTR: a little heavier but with the little bugs worked out.

  4. Aluminum still available online? I was actually interested in the 24mm in a 27.5 (gasp) non-boost spacing (gasp) as a potential replacement to my OG ZTR Crests. 30mm internal seems silly for a 2.3 tire, and I’m guessing that width rim would stretch the tire in such a way that it might rub my Highball frame and maybe even my stepcast 32 fork (15×100).

  5. They saved 50g on the front hub with “more precise machining of these alloy hub shells”? That sounds… wrong.

  6. Anyone know why DT Swiss are not using asymmetrical/offset layouts for their disc rims? Would love to hear the answer – from where I’m sat it’s all pro’s no con’s.

    • They use offset for some of their lighter XC options in alloy, but not for carbon or heavier duty rims. That might hint at your answer.
