Our review

Still among the best enduro wheelsets, although you’d be hard pressed to tell it apart from its cheaper siblings
Pros: Tough rims; good ride quality; light enough to compete with carbon
Cons: One wheelset went slightly out of true after many hard landings; not the fastest engaging freehub; hard to justify the extra £500 over DT’s own E 1900

The EX1501 is DT Swiss’s top-end alloy wheelset for enduro riding. It’s a common choice among enduro racers and is often stocked on high-end trail/enduro bikes and with good reason.


Because of their popularity among OEMs, we’ve put time into several sets here at BikeRadar, and have consistently been impressed.

DT Swiss EX 1501 Spline One 30 ride impressions

They’re not the lightest, and the 36 points of engagement freehub ratchet is unlikely to win top-trumps points for speedy power pickup either. But, realistically, they’re light enough to match the responsiveness of anything any of the other wheelsets I tested and the relatively slow (ten degree) freehub engagement never bothered me either.

You can upgrade the freehub ratchet to a faster 54-tooth version.

You can upgrade the freehub ratchet to a faster 54-tooth version if you like and the stock ratchet has proven reliable and is easy to service.

These tough rims have an internal width of 30mm.

I’ve put a lot of time into these wheels and they’ve proven tough and reliable, although one set needed truing after some serious abuse.


Ride feel is about as good as anything else I’ve tested recently too, though you’d be hard pressed to really notice the difference over the cheaper E 1900.
