Partnering with trusted dynamo maker Shutter Precision, the wheel specialists at DT Swiss have created the 350 SP PL-7 dynamo hub and two affordable pre-built aluminum Gravel Dynamo wheels. Whether you are looking for inexhaustible power to light up your next ultra-distance adventure or simply a reliable always-on lighting setup for year-round bike commutes, DT now offers several no-nonsense dynamo generator solutions backed by a brand you already know and trust…

DT Swiss is getting back into the generator hub dynamo game, working together with Shutter Precision to build modern dynamo hubs & wheels to deliver unlimited power to the latest crop of road, all-road, and gravel bikes. And while the trusted generator tech inside isn’t really new, DT has built it into their solid & reliable 350 hub series with straightpull lacing, 12mm thru-axles, and centerlock disc brake compatibility.

This is DT Swiss’ first dynamo in over 25 years – since their S’Light hub from the 90s – and seems to fit well with the growth of ultra-distance racing, amateur bikepacking, and maybe even a resurgence of riding versatile bikes for fun and commuting.

Because really, having to remember to keep your lights charged just means that eventually, there will come a time when you don’t have lighting when you need it. Why worry about it, when you can always have pedal power to light your way or charge your devices.

Tech details

Inside the DT-made 350 SP PL-7 hub shell are standard Shutter Precision 7 series dynamo hub guts – made by SP in their new high-tech factory in Taichung. That means you get a reliable 6-volt, 3-watt power output claiming 72% efficiency while pedaling at just 15kph. DT says that means “really stable” power to cover your lighting needs, even at relatively slow riding speeds around town or even off-road.

Of course, getting unlimited power adds some resistance as you pedal. SP claims <1W of added drag up to riding at 30kph. And then only when you switch on your lights does it require more power out of your legs. That sucks 4.2W at that 15kph threshold or between 6-7W at 30kph (hence that efficiency percentage claim.)

Plus, the dynamo is StVZO tested & certified, so it will provide the required lighting to ride at night under Germany’s strict rules.

New DT dynamo options

DT makes it easy for riders to add a dynamo power setup to their current bike, or otherwise for a complete self-powered new bike build. DT offers the new 350 SP PL-7 dynamo hub on its own, in just one configuration for road- & gravel-focused custom wheel builds. Or there are 2 affordable pre-built front wheels to choose from, slotting directly into the 2 aluminum options in the DT Swiss gravel bike wheel family, updated last year.

DT Swiss 350 SP PL-7 dynamo hub

  • Shutter Precision 7 series dynamo internals
  • 6V3W power output, so StVZO-compliant
  • centerlock disc brake
  • 12x100mm thru-axle
  • 24-hole drilling then for straight-pull spokes only
  • 376g claimed hub weight

G1800 Spline DYN alloy gravel dynamo front wheel

  • alloy centerlock disc brake dynamo front gravel wheel, of course with the new DT 350 SP PL-7 dynamo hub
  • sleeved aluminum rim joint
  • 24mm internal x 25mm deep, hooked tubeless-ready rim
  • pre-taped, tubeless valve included
  • 24 straightpull DT Aero Comp spokes
  • laced 2x with Pro Lock, Squorx Pro Head aluminum nipples
  • 1098g claimed weight (+234g vs. standard G1800 front wheel)

GR1600 Spline DYN alloy gravel dynamo front wheel

  • alloy centerlock disc brake front dynamo gravel wheel, thus the DT 350 SP PL-7 dynamo hub again
  • welded aluminum rim joint
  • 24mm internal x 25mm deep, hooked tubeless-ready rim
  • pre-taped, tubeless valve included
  • 24 straightpull DT Aero Comp spokes
  • laced 2x with Pro Lock, Squorx Pro Head aluminum nipples
  • 1075g claimed weight (+245g vs. standard GR1600 front wheel)

DT Swiss Dynamo – Pricing & availability

If you want to custom-build a dynamo wheel to match your current setup, you can pick up the DT Swiss 350 SP PL-7 dynamo hub on its own for $237 / 175€. For comparison, that’s the same price as Shutter Precision’s own J-bend PL-7 hub, and just about 2x the cost of DT’s standard non-dynamo 350 road hub.

The easier and better value solution is one of 2 pre-built aluminum gravel dynamo wheels, which sell for just $95/69€ more than their non-dynamo analogue. The sleeved rim G1800 front wheel sells alone for $343 / 249€, or add in a matching rear wheel for a $688 / 499€ complete wheelset (2069g pair).

The slightly lighter GR1600 setup with a welded rim retails for $443 / 321€ for the front only, or for $923 / 669€ as a complete wheelset with a matching rear wheel (1993g wheelset).

The new hubs and wheels are officially available starting today. But depending where you are in the world, it might be the end of this month or early December before you will be able to get one in-hand.

All new DT dynamo hubs & wheels include the standard SP wire connector that you will need to connect to a custom wiring setup on your own bike, whether you connect directly to a dynamo-specific headlight alone or additionally to a taillight and/or USB accessory charging setup like the Sinewave Revolution. It’s not the easiest bike building project to complete. But once you do, you’ll never have to worry about battery-powered lights on your road or gravel bike again!

As someone who has never looked into dynamo hubs the price seems pretty reasonable. This would be pretty cool on an ultimate commuter bike.

I use a Schmidt setup on my commuter bike for the past 6 years and will never go back.

Can the bearings be replaced by a shop/consumer, or will the hub need to be shipped to the far east like one would need to for any other SP hub (inc. Exposure Revo)?

Wow, I hadn’t thought of that, as I’m not that familiar with the other SP products. That is an excellent question, hopefully either the BR crew or someone from DT will chime in with an answer.

Speaking as a shop wrench who has had to warranty SP hubs: No, they are not user-serviceable or shop-serviceable. We have to deconstruct the wheel and ship the hub back to Taiwan. The same is true for SON (Schmidt) hubs getting sent back to the warranty center, but the failure rate I’ve seen for Shutter is definitely worse. Kind of surprised DT Swiss partnered with them, actually.

When looking at their technology page, it seems that the hubs can be serviced through DT’s network of service centers. Sounds pretty good to me, knowing their reactivity and top notch service for my ARCs.

I sent my SP hub to the distributor (in the UK) and they sent me a replacement hub. No waiting for international postage. (I did pay a service fee as it was well out of warranty).

so… 24H is considered normal now?

For gravel, yes of course. I think it’s been a solid decade since I’ve had anything more than a 24h wheel set on my gravel bikes.Even top tier XC wheels are 24h these days.

Why do they only have Center lock? I’d rather have 6 bolt

Many DT wheels ship with CL to 6-bolt adapters in the box to satisfy people like you. Personally, I far prefer the ease of use of CL rotors, and because Shimano’s patent expired a while ago, it’s easy to get CL versions from many manufacturers.

“That sucks 4.2W at that 15kph threshold or between 6-7W at 30kph (hence that efficiency percentage claim [72%].)” – The math works (approximately), but not the logic. Efficiency is power output / power input; based on the graph it appears to be about 3 W of electricity generated for 4.2 W of muscle power at 15 km/h, hence that efficiency percentage claim of 72%. It would be good if this was clarified/corrected in the text.

I’m excited for this, but wish they had a 28 or 32 spoke option for bikepacking and touring needs.

…and a version for J-bend spokes.
