With e-bike torque and power numbers entering a new phase, Ontario-made Project 321 is one of the few brands making sure its hubs are up to the task. With its new G3Ti hubs, the brand overhauls its existing G3 hub to withstand the most powerful motors. Or riders, if you’re a wildly-powerful singlespeeder looking for a hub to take that distinctive flavour of abuse. But this one is mainly aimed at the e-crowd.

As the name hints, P321 employs a new titanium driver to help withstand the mega Nm’s unleashed by Avinox, the latest Bosch motors and, with the hubs withstanding 1,100 Nm in testing, pretty much any other system coming down the pipeline. That number is tested and backed by a 10-year warranty that includes eMTB use.

Not just Titanium

Along with the new e-specific release, P321 is also offering a very-slightly simplified version of its G3 hub. In place of the 6-lock, which allows one hub to switch between centerlock or six bolt disc rotor standards, G3 will be available in either standard for a lower price.

But if you already own G3 hubs and want that fancy Ti driver, it is fully backwards compatible with existing G3 and RG3 hubs. We’re always happy to see compatibility.

P321 G3Ti: Not just a driver

While titanium is in the name, P321’s re-vamp of the G3 hub for e-specific use goes well beyond the titanium driver body. While the combination of a harder metal than the usual aluminium driver shell and P321’s M-Pulse drive mechanism are core to the new hub withstanding 1,100 Nm in testing, other changes help the G3Ti hold up to the daily abuse eMTBs dish out.

P321’s changed the way in which its three-step pawls engage to help deal with heavier loads. Instead of two of eight pawls engaging at once, as on the G3, the G3Ti is phased so that four of eight pawls engage at once. That gives the new hub 144 P.O.E. (over a 72T drive ring) for 2.5-degree engagement.

The update makes P321 one of the few hub brands (alongside Chris King) to back their goods up with a warranty for high-torque eMTB use. P321 offers a 10 year warranty on the hub shell, axle and titanium G3Ti driver body and a three year warranty on the pawls and drive ring.

Double bearings for burly bikes

Another big change hides inside the G3Ti hub shell. A second row of 3802 bearings on the G3Ti replaces a single row of 6802 bearings on the drive side of the G3, significantly adding stiffness and durability to the axle and bearing layout of the new hub, even when used with heavier eMTBs.

Another e-specific change is the move away from P321’s exclusive 6-lock rotor mount. That system, which remains on the flagship G3 hub, isn’t always compatible with eMTB speed sensors. So P321 is offering the G3Ti in 6-bolt or center lock rotor mount standards. As mentioned above, since P321 made this change for the G3Ti, it’s also now offering a less expensive version of the G3 hub without 6-lock for any rotor-mount loyalists that don’t want the option to switch between rotor mount standards.

P321 G3Ti: Pricing and availability

Project 321’s pulled a nice move with the G3Ti pricing, keeping it identical to the existing G3 hub. Like the OG, the new Ti and 6-bolt or center lock hubs are available in all three major freehub standards: HG, XD and Microspline (MS).

G3Ti hubs are available for pre-order now. Black and silver hubs are being machined in P321’s 42,000 square foot facility outside Toronto now and should ship by mid-October. The eight anodised colour options will follow after that.

G3 6-Lock hubs (Existing) start at $650USD/$905CAD
G3Ti Titanium driver 6-Bolt & Center Lock hubs (New) start at $650USD/$905CAD
G3 6-Bolt & Center Lock hubs (New) Start at $600USD/$835CAD
