DT SWISS 350 2021 + FRONT BLACK CENTERLOCK DISC HUB

Design and construction

The 350 hubshell is a milled aluminum body on a lightweight axle with sealed cartridge bearings. On the 2021+ DT 350 the axle is stiffer than the old version and the end caps are the plug-in type, so the same 350 hub converts between quick release and thru-axle standards with a cap change. The flange spacing is classic DT, which means every spoke calculator on earth knows the 350 and the wheel builds true first time.

A front hub is a bearing carrier with flanges, and that is the whole job of the front 350: two sealed bearings on a stiff axle, end caps for your fork's standard, and flanges spaced to give the spokes a good bracing angle on the rotor side. There is nothing to engage and nothing to swap. Everything written about freehubs and engagement applies to the rear hub only; what you get up front is the same shell quality and the same seals without any of the moving parts.

How it rides

A DT 350 does not draw attention to itself, which is exactly what you want from a hub.

For most riders the 350 is the right trade.

On the road or the trail the front hub's job is to disappear: spin freely, keep water out, and hold the flanges still so the wheel tracks where you point it. The front 350 does that with the same bearings and seals as the rear and none of the rear's complexity, and because a front wheel carries less load and no torque it stays true longer than the rear on the same rim. When the rear finally needs a look, the front usually does not.

Specifications

Which version this is

Version notes. Centerlock rotor mount, QR 5x100mm, Thru Axle 12x100mm, Thru Axle 15x100mm, Thru Axle 15x110mm Boost and more, 28h, 32h, about 144g, in black. If your frame or fork uses a different standard, the other versions of the 350 on this site cover it.

Centerlock is the lighter, quicker rotor mount: a splined rotor drops onto the hub and a single lockring holds it, so a rotor swap takes a minute with a lockring tool and there are no six small bolts to torque or lose. Shimano and most current road and gravel rotors are centerlock; 6-bolt rotors fit with an adapter.

Sizes, fit and compatibility

The DT Swiss 350 2021 + Front Black Centerlock Disc Hub comes in the drillings listed on this page and in the axle and rotor options shown in the configurator: centerlock disc, 6-bolt disc or rim brake, road and MTB spacings including Boost.

The 350 is a J-bend hub, which opens up every spoke we stock. We build the 350 onto DT Swiss rims, Stan's, WTB, Race Face, HED, Velocity and most carbon rims in the catalog. Tell the configurator your bike type and weight and it will suggest a spoke count that suits the drilling you pick.

Build it into a wheel

This hub is live in our Custom Wheel Program for gravel and road disc, track and road single-speed, mountain bike, MTB single-speed and fat bike builds. Start a build with the DT Swiss 350 2021 + Front Black Centerlock Disc Hub and the configurator opens with this exact hub pinned at the top of the DT Swiss list — you choose the rest of the parts and it validates every combination as you go.

Building it at ProWheelBuilder

DT makes the 350 in Switzerland and Poland; ProWheelBuilder is an independent custom wheel builder in Georgia, not the manufacturer. We have built enough DT 350 wheels to know its flange dimensions by heart, but we still cut spokes from the measured geometry of the rim in hand and bring every wheel up in stages with a tension gauge before truing and stress-relieving it.

The configurator shows only rims and spokes that can be built with the drilling you choose, strikes through combinations that are not made, and prices the wheel live.
