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 dynamo in 350 SP hub & DYN-series gravel wheels
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 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!
