Bastion Panterra Gravel Bike
Gravel, done differently — 3D-printed titanium and filament-wound carbon, clearance for 50mm rubber, and a finish you can see across a car park. Try not to baby it.
Bastion Panterra Gravel Bike
Meet the Panterra: Bastion’s gravel bike, and very much a Bastion first — the same 3D-printed titanium lugs and aerospace-grade carbon construction the Melbourne workshop has spent years refining on the road, now pointed at the unsealed roads, the doubletrack, and the long way home. There’s clearance for a genuine 700 x 50C tire front and rear, dropped stays, an integrated barstem and fork, and the kind of polished-titanium presence that makes the Panterra look like nothing else on a gravel ride. It’s developed primarily around modern 1x electronic groupsets, configured from the ground up through Bastion’s Design Portal, and built one at a time over the better part of seven months. This is not a bike that arrives in a box. It arrives as yours.

More about the Panterrs
Bastion built their name on the road — the Archetype, the Superleggera, the Archangel — a small Melbourne workshop turning 3D-printed titanium and filament-wound carbon fiber into bikes that look and ride like nothing else coming out of a factory. The Panterra is what happens when that same obsession leaves the tarmac. It's a gravel bike, but it carries every bit of the engineering DNA that made the road bikes worth the wait: titanium lugs printed to shape rather than cut from stock, carbon tubes wound on a filament machine rather than laid up in a mold, and a hand-finishing process measured in days, not minutes.
The headline, for a lot of riders, will be the clearance. A true 700 x 50C front and rear opens the Panterra up to a tire platform most road-bred brands wouldn't recognise as their own — the kind of contact patch that turns rough, loose, sketchy surfaces into something you ride with confidence rather than survive. Bastion pair that with dropped stays and aerodynamically sculpted carbon tubes, so the bike that swallows 50mm of rubber doesn't ride like a tractor. It's quick. It's planted. And it goes a very long way past the end of the tarmac before any of its road manners start to fade. It's developed primarily for modern 1x electronic groupsets — Bastion lists GRX Di2, SRAM RED XPLR E1, and Campagnolo X among the options — which keeps the front end clean, the cockpit tidy, and the whole bike pointed at the way gravel is actually ridden now. The barstem and fork are integrated, the bearings are CeramicSpeed, the cages are titanium, and the wheels can be Bastion's own or a set from Zipp, Princeton, or Lightweight depending on where you want the bike to sit on the spectrum from fast to featherweight. None of it is off a shelf. All of it is chosen, in conversation, for the rider it's being built for.
That conversation is the part we care most about. Every Panterra runs through Bastion's Design Portal, where geometry, finish, and spec are configured from the ground up — and that's exactly the kind of build we love to shepherd at Regroup. A bike this personal rewards getting the foundations right: the fit that the whole geometry is drawn around, the gear ratios chosen for the events and the terrain you're actually planning, the tire and pressure for the surfaces you'll really be on, the finish you'll still love three years in. That's where Regroup FIT and our build expertise come in. Start a Panterra story with us, and we'll help you make every one of those decisions properly — because on a custom bike built around your body and your riding, the position isn't an afterthought. It's the whole point.
THE FINER DETAILS
Printed Titanium, Wound Carbon — and Nothing Off a Shelf
At the heart of every Bastion is a construction method almost no one else is using: titanium lugs grown layer by layer on a 3D printer, then bonded to carbon fiber tubes wound on a filament machine and sculpted for aerodynamics. Over 130 hours of precision machine work — from printing and CNC machining through to polishing and painting — and more than 70 hours of hand craftsmanship go into each frame. The result is a gravel bike that's distinctly, visibly different: polished titanium, dropped stays, and tube shapes you won't find anywhere else. Because, as Bastion put it, it matters.
Clearance for 50mm. Confidence for Everything After the Tarmac
With room for a genuine 700 x 50C tire front and rear, the Panterra delivers the kind of unsealed capability that lets you explore further without second-guessing the surface. A bigger contact patch means more grip, more comfort, and more momentum across exactly the distances where saved tension in the body becomes saved energy at the pedals. This is a gravel bike engineered to go big — and to keep its composure when the road runs out.
Built Around You, Through the Design Portal
Every owner arrives with a different story, a different riding style, and a different idea of what their bike should become. Through Bastion's exclusive Design Portal — and with Regroup alongside you — those ideas are turned into a bicycle that's unmistakably yours: geometry, finish, wheels, groupset, and the hundred smaller choices that separate a bike that's technically yours from one that genuinely is. Meaningful difference, as Bastion say, begins long before the first component is made. Lead time is around seven months from order confirmation, and it's worth every week.
