Every bike out of Paul Budnitz’s workshop is already a little different. Now with the latest version of his Model Ø, comes the Ø:G. The limited edition ti gravel bike pairs their swooping Zero titanium frame with a Gates-belt drive, a Rohloff internal hub pushed by SRAM hydro levers, and a plush set of dirt grinding 37mm WTB tires.

Budnitz’s new Ø:G is a limited edition take on his all-road titanium Model Ø bike. That double toptube, cruiser inspired frame already delivered a plush ride, and offered the perfect platform to create a bulletproof gravel grinder.


Now the custom butted 3/2.5 ti FlyLite frame weighing 3.8lb/1.7kg is destined to head even further from the tarmac, paired with a Whisky Carbon fork.

Budnitz Ø:G – Tech Details

Designed to be equally at home shredding trails, grinding away gravel, or just racking up the road miles, the Budnitz Ø:G is the epitome of a do-it-all mixed-surface gravel road bike that isn’t likely to need much (if any) maintenance.

The centertrack Gates CDX Carbon Drive belt certainly isn’t going to need much attention, neither is the 14-speed internal Rohloff Speedhub.

The trick to the dropbar Rohloff setup, the Ø:G uses the shifters from a set of SRAM Force 22 road hydraulic disc brake levers with their internal ratcheting mechanisms removed to control the internally geared rear hub without a bulky, less ergonomic shifter à la the Gebla Rohbox mod, something they do for all dropbar Rohloff builds.

Finishing out the gravel grinding setup, the $6600 base Ø:G features a Easton alloy drop bar, stem & seatpost, plus a set of dirt-loving 37mm WTB Riddler tires on in-house handbuilt tubeless alloy wheels. If you feel like the handmade titanium frame needs some more fancy parts, an Enve Easton carbon component upgrade only adds another $250.


The Model Ø comes in just four standard frame sizes, and then each complete bike is built up to individual buyer spec. Get yours now straight from Budnitz.



  1. Is Budnitz still ripping off designs from more talented people? Let’s go back to a Black Sheep Bikes Facebook post from 2012:

    “We rarely rant here at Black Sheep Bikes. We see no need to defend what we do as bike builders and similarly we leave others to do as they please. If you like what we do great, if not cool. There is many talented people making bikes in this world. Check out your local builder for instance. We build the bikes we love out of the passion for our trade and our love for bikes. Pretty simple. However we do feel that the we need to clarify some things as we have gotten a lot of questions so the air needs to be cleared. 5 or so years ago we were approached by a fella we will call Mr. B. He came to us with a need for a quality built bike that would suit his needs, keep him fit, and have some style. No problem. We built him a Speedster style frame, belt drive, internally geared hub, internal routing, etc.. Great commuter and he was very satisfied. So much in fact that he wanted another with a little different style and bigger tires. Kind of a urban thrasher that can fit in a travel case. Done. Another happy customer. After awhile he approached us with an idea of helping him build a bike company under his own name. He wanted us to make him replicas of the bikes we had already made with the potential to go over seas and have them massed produced. As you can imagine we felt like this wasn’t the best idea for our company and went against why we build these bikes with our own hands here in Colorado in the first place. Nothing against bikes made out of country and in Asia as many are high quality and almost all are handmade by skilled workers. It just sounded boring and not our style. So we told him we weren’t interested. Mr. B however is a man with money and the means to do as he pleases so he took our bikes had them replicated(kind of) at another American bike company and now has some being produced over seas. Damn! Wasn’t what we thought was going to happen. Oh well we suppose. We still get to build our dream bikes, one at a time, with our own hands here in Colorado. What this really boils down to is a choice. You can buy a bike from a man who has his name on it with no other connection to his product or the hard work that others have put into it. Or you can buy a bike from people who love what they do and do it themselves, pour their soul into their craft, and actually have a passion for bikes. The point is, before you drop a bunch of your hard earned cash on a Budnitz…give a guy like Curtis Inglis a call first. You will be glad you did.”

    • Generally Rohloffs are a minimum of a pound heavier. Probably more like a kilo vs a light drivetrain. They’re bombproof, but they have their drawbacks.

    • I once made a comparision between an Shimano Alfine 11 Di2 beltdrive setup against Ultegra R8000 Di2, DA R9100 Di2 and SRAM RED eTap (all with disc brakes) and the difference in favour for the 2×11 setups is between 900 and 1200 metric gramms. A Rohloff Beltdrive-Setup is almost the same weight as the Alfine 11. The slightly bigger shifter, shiftbox and torque anchoring might add some 100-200gramms over the Alfine. So it would be quite save to say, that it shouldnt be more than 1500gramm heavier. I dont know the weight of a SRAM Eagle, but i think its not that much lighter than a DA R9100.

      What is more impportant is, that the weight distribution is much more to the rear-wheel and that it is almost every time necessary to have special features on the frame to properly tension the chain/belt and mount the Rohloff Speedhub because of the torque anchoring. Other than that it is the nicest gears I have ever (and still do) ridden on a bike.

      It is possible to setup a Rohloff-Gravelgrinder as a 10,5kg-bicycle, even with a steel-frame. With some tricks like a Ti-Frame or Tubeless, sub 9,5kg may be possible as well – without compromising the durabillity.

    • Hi mudrock, thanks for the question! And thanks for adding your findings, dolan and TI NO. We’ve found similar numbers (Rohloff is ~1kg heavier) when comparing to a hypothetical derailleur setup. As pictured above the complete bicycle weighs 23.25 lbs. That’s with the alloy cockpit, flat pedals, and tires set up tubeless.
