DT Swiss GR1600 Spline Review: Do You Really Need Carbon Gravel Wheels?
After 500 km across mud, singletrack and road, DT Swiss’s alloy GR1600 challenges the value of high-end carbon.
After months of testing everything from full-carbon race wheels to wide, do-it-all setups, one thing became clear: performance is easy to find. But can a budget model compete? The DT Swiss GR1600 Spline quietly closes that gap.
Introduction: Performance Is Easy—Value Is Not
I’ve been testing a wide range of gravel wheels lately, full-carbon race setups, super-wide all-road options, and plenty of “do-it-all” builds designed to cover every scenario.
Most of them deliver. They’re fast, refined, and, in the right conditions, seriously impressive.
Which is exactly what makes the DT Swiss GR1600 Spline so interesting.
DT sent me this wheelset for testing, positioning it as an alloy, mid-range option well below the carbon heavy hitters. On paper, it’s the outlier. Out on the trail, and over time, it demonstrates what actually matters when you’re not chasing marginal gains at the sharp end of a race.
The Test.
I took these wheels out for over 500 km. The GR1600s were on my bike across dry, dusty singletrack, sticky forest mud, and everything in between, including a 115 km road sportive, all with the same set-up: Continental Terra Trail 45 mm, run Tubeless at 2 bar.
On the Ride: Composure Over Everything
The standout trait here is composure.
On rough descents, the wheels feel planted and predictable. There’s no twitchiness, no sense that they’re being knocked off line. You can stay relaxed on the bike, let them run, and trust that they will hold you where you point them.
Once up to speed, they carry momentum well, in a steady, efficient manner that becomes more noticeable the longer the ride goes on.
Being aluminium wheels, the weight does show up when you push hard. Accelerating out of corners or trying to snap onto a wheel, there’s a slight delay compared to lighter carbon options, but you would only really notice if you had been riding a full carbon set before.
But in softer conditions, that same weight works in your favour. In mud and draggy surfaces, the GR1600s keep rolling, holding momentum where lighter setups can literally get bogged down.
Speed, Feel, and Perspective: The Carbon Question
There is a difference between these and high-end carbon wheels. Naturally, with more high-end specs, the acceleration is sharper, and the engagement is quicker. Everything feels more immediate. But that difference only really becomes obvious when you’re riding multiple wheelsets back-to-back, looking for it. On the flip side, if you are looking for an upgrade from your stock wheels, you will notice an improvement in everything and have a more enjoyable ride.
Unless you’re racing at the very front, where marginal gains actually decide outcomes, weight becomes less critical than consistency. What matters more is how a wheel performs over time, across surfaces, and under fatigue.
And that’s where the GR1600 makes its case.
Build & Practicality: Quietly Excellent
This is classic DT Swiss: simple, functional, and built to last.
The alloy rims are properly sized for modern gravel tyres, giving good support at lower pressures without feeling vague. The 350-based hubs are proven, serviceable, and built around the Star Ratchet system that prioritises reliability over flash.
Tubeless setup is as straightforward as it gets. Both tyres seated first time with a track pump. I added Dynamics sealant, and within a few pedal strokes, I was ready to ride. It’s not exciting, but it can be such a pain when the wheels dont come set up right, and trust me when I say that some high-end wheels do not come set up right!
At around €600, the GR1600 sits firmly in that sweet spot: a genuine upgrade without tipping into carbon territory. There are cheaper, similar wheels out there, but you pay for the DT Swiss name and quality.
Durability & Trust: The Real Upgrade
More than anything, these wheels are dependable.
Across rough singletrack, broken gravel, and wet forest tracks, they never felt like a weak point. No unwanted flex, no noise, they just worked.
And that counts for more than a few saved grams.
Because for most riders, the goal isn’t to have the lightest setup, it’s to have one that works, every time, without question.
The Trade-offs:
These wheels are not trying to be something they’re not. They are a good, dependable wheelset.
You’ll notice the weight when accelerating hard. The engagement is solid but not especially quick. But those trade-offs are to be expected in this price range..
Verdict: Closing the Gap
There’s no question that high-end wheels deliver performance. They’re faster to accelerate, sharper under load, and undeniably refined.
But what the DT Swiss GR1600 Spline highlights is how little of that most riders actually need.
Over 500 km of mixed terrain, they proved stable, durable, and consistently fast in the ways that matter outside of racing. The difference to more expensive wheels is there, but it’s smaller, and harder to justify, than you might expect.
If you’re looking for a wheelset that upgrades your bike in a real, tangible way, without disappearing down the marginal gains rabbit hole, this is it.
Not flashy. Not featherweight. Just very good where it counts.
