Intro
DT Swiss’ 350 hubs are deservedly popular for their blend of reliability and value. One of the tradeoffs there has been that fast engagement and flashy color options haven’t been on the menu. That’s all changing though, and DT is now offering their faster-engaging Ratchet DEG system in the 350 rear hub and has a run of limited-edition color options to go with it. And while they’re at it, they’re now offering their top-tier carbon fiber MTB rims on their own for folks who’d prefer to build up custom wheels, too.
350 DEG Rear Hub
The main design elements of the 350 DEG rear hub are nearly the same as the 180 and 240 DEG hubs that DT launched last year. Like all of DT’s current hubs, the 350 DEG uses a pair of toothed ratchet rings in the freehub, which engage all of their teeth simultaneously. The main difference between the 350 DEG rear hub and DT’s longstanding standard (i.e., non-DEG) 350 is that the 350 DEG uses larger diameter ratchets to allow for more teeth and faster engagement.
[Technically, the 350 DEG hub isn’t entirely new, but Reserve had the exclusive rights to use it in their complete wheels until now.]
DT has slightly tweaked the bearing arrangement in the 350 DEG hub as compared to the 240 DEG that’s been on the market since 2024 to use larger ones in the hubshell for increased durability at the expense of a little bit of weight. Like the 240 DEG, there’s still room to remove the bearings without removing the drive ring from the hubshell (which needs to be done on the standard 350, and can be tricky) — the bearing sizes and spacer configuration are just slightly different between the 240 DEG and 350 DEG. The freehub bodies are cross-compatible.
It is worth mentioning that the 350 DEG comes with 72-tooth ratchet rings instead of the 90-tooth ones found in the higher-end variants. The Reserve-only 350 DEG hub that was offered up to this point used the 90-tooth ratchet rings, which are interchangeable with the 72-tooth ones.
DT is also offering the 350 DEG hubs in a limited run of pink, blue, and green colors. Those versions are offered in Boost spacing with six-bolt rotors, an XD driver, and 32-hole drilling only; matching colored 350 front hubs are also available. Only 350 of each color will be made.
The 350 DEG hub will also be available in DT’s standard black, with a wider array of axle / freehub / drilling options. The standard 350 rear hub sticks around unchanged, as does the 350 front hub.
Pure Carbon Rims
DT is also launching three new carbon fiber rims — the XRC 310, XMC 320, and EXC 330 — aimed at XC, Trail, and Enduro use, respectively. These rims aren’t entirely new — they’re used in DT’s flagship 1200-series wheelsets — but are offered on their own for the first time.
The overall design of the rims is similar, just tailored for their respective use cases. All three feature a 30 mm internal width and an asymmetric profile to even out the spoke bracing angles.
DT says that they’ve developed some new techniques for manufacturing carbon rims that are deployed in the Pure lineup. The rims are laid up in a single mold rather than in segments that are subsequently joined together, as is the case with a lot of carbon rims. DT says that by constructing the rims in a single mold, they’re able to perform individual inspections of each layer to catch potential manufacturing defects. They also wrap full layers of carbon fiber over the bead seats without any cut fiber ends in those areas to improve impact resistance.
The lightest rim in the Pure lineup is the XRC 310, which is meant for XC race use. It’s offered in a 29’’ diameter only with 28-hole drilling and comes in at a stated weight of 373 grams per rim. DT imposes a 110 kg (243 lb) maximum system weight (rider + bike) for the XRC 310.
The Trail-oriented XMC 320 is available in 27.5’’ and 29’’ diameters, with the same 28-hole drilling as the XRC 310. At a stated weight of 470 grams per rim (29’’ diameter), it’s on the light side for a carbon fiber Trail bike rim; as with the XRC 310, DT imposes a maximum bike + rider weight for the XMC 320, though it increases to 120 kg / 265 lb.
Finally, the EXC 330 rim is the beefiest Enduro-focused rim of the trio. It’s offered in 27.5’’ and 29’’ diameters with either 28- or 32-hole drilling and weighs a stated 535 grams for the 29er version — fairly typical for a burly, high-end carbon rim. DT’s maximum system weight for the EXC 330 is 130 kg / 287 lb.
All three rims are covered by a lifetime warranty. Damage that is incurred while riding that is deemed to be a non-warranty issue is covered by DT’s crash replacement policy, which offers the original owner a replacement rim for $179 USD.
Bottom Line (For Now)
DT’s 350 hubs have long been a go-to option for folks after super reliable, no-frills hubs at a comparatively affordable price, and now there’s an option for folks who’d prefer faster engagement than the 36 points that the regular 350 rear hub delivers. Offering their top-tier carbon rims a-la-carte is a welcome move, too, and we’ve already spent a ton of time on the EXC 330 rims as part of the EXC 1200 wheelset.
