We got a tease of the retro-tastic Cyber Cycles x Agresti Frameworks Grawumm dirt drop mountain/gravel bike back at Bespoked. But now it is a real limited edition production steel bike you can buy. And of course, you should build it up with a full complement of Cyber’s style-matching steel & ti components – cranks, fork & stem!
Cyber Grawumm steel gravel mountain bike by Agresti
Back at Bespoked, Cyber showed us their fully fleshed-out line of modern tubular steel direct mount Cyber Cranks. The also showed off some uniquely retro Cross Blade forks, with either steel or titanium legs, plus modern steel threadless Crypto stems with old school quill styling. And to showcase them all was this prototype Cyber x Agresti Grawumm.
The concept was to embrace the idea that modern gravel bikes are just rigid dropbar mountain bikes from the 1990s.
“The bike your parents always warned you about. Fast, comfortable and very versatile.“
At the Bespoked show we got word only 2 were made. One came to Cyber founder Christian Thomas for the show. But since he “had so much fun building [it]”, frame building partner Stefano Agresti welded one for himself, too. And Cyber received such positive feedback and interest at the show, that they decided to put it into limited series production.
Tech details
The Cyber Grawumm is a suspension-corrected steel gravel bike frame with retro MTB inspiration, but plenty of modern details.
Each frame is handmade in Germany by Agresti from Columbus Zona & Life double-butted tubing. Cyber claims a frame weight of ~1900g for a medium, and the complete bike above weighs 9.8kg with pedals.
The compact frames feature a short 44mm headtube, a BSA threaded bottom bracket, max 2.1″/55mm tires, and CNC-machined bits. Plus, there are 3D-printed stainless steel dropouts with a Syntace X12 thru-axle, flat mount 160mm brakes, and replaceable derailleur hanger. Cyber ships bikes with the axle and an alloy Salsa Lip Lock clamp to secure a 31.6mm seatpost.
Cyber is going for a clean routing look on the Grawumm. So, internal routing for the rear brake comes standard, which includes 3D-printed internal guides to route cables inside. Internal shift cables are also possible, but an extra add-on since so many modern gravel bikes opt for wireless shifting. Their Cross Blade fork also gets sleek routing through the inside of the left leg.
Cyber Grawumm – Pricing, options & availability
The Cyber Grawumm is available in four stock sizes (S-XL), made to order inspired by old school MTB proportions.
The smallest rolls on 27.5″ wheels, while the three larger are 29ers.
Frame pricing starts at 1875€ unpainted, so you get to define whether it gets more retro or more modern styling. This 90s Team paint job is possible, but isn’t exactly easy or cheap. And then buyers can customize to their heart’s content, adding rack mounts, other extra braze-ons, internal shift routing, or even custom geometry if you need.
Order a frame direct from Cyber now, by sending a message to get the ball rolling. Or then, if you want a size M, you might even be able to snap up that first show bike right away!
Then, figure out all the other Cyber components you’ll need to finish off the retro-modern build. At least you should start off with a Cross Blade fork & Cyber Cranks…
