Why you'll love it
"Top-quality handbuilt steel frame that mixes impeccable handling, comfort and fun in one excellent package." July 2020 - Roadcc.
The Bivio Gravel was born for adventures across land, desert, and ice. Cruise over Tarmac-free roads or adapt it to be your 'do anything' commuter. Built from triple-butted, custom-formed Columbus Spirit tubing, the Bivio Gravel provides no-hassle, smooth riding, mile after mile.
The Bivio-Gravel features our tried and tested adventure geometry, similar to our endurance road bike geometry, so you can cover distances quickly or just cruise around exploring. We tuned the head angle and wheelbase to give you stable handling over twisty roots and rocks. For 2020, we have increased the tyre clearance to 42mm for 700c wheels and 47mm when running 650b. If you plan to tackle mud, snow or ice, the Bivio Gravel won't restrict your tyre choice.
On the frame you'll find mounts for racks and guards, plus everything you need for day-in-day out riding and the ultimate trip - whether it's a weekend of shredding, bike-packing, or gravel racing.

Gravel geometry and premium steel
Modern road geometry paired with off-road ability. We have relaxed the head angle and adjusted the chainstay length so you can comfortably cover kilometres on the road, as well as sweep, skid, and drift with glee on the trails.
Condor Smart Cabling
Our Smart Cabling system allows you to fit any groupset, whether it's mechanical or electronic. And if you want to change to Di2/EPS, mechanical, or eTAP in the future, you don't need to worry about messy cabling or compatibility.
Custom steel designed by Condor, made by Columbus
Columbus Spirit HSS is the highest level of steel produced by Columbus. The tubes are seamless, which means the tube is formed by stretching it without welding a joint. The tubes are triple-butted with a high tensile strength, and hardened using precipitation, enabling the tube to have an excellent surface and strength to weight ratio. The tubes are head treated to improve strength and resistance to damage. The nearest comparable tubing from Reynolds is 853.
Performance fork and 44mm head tube
We pair our performance steel with the lightest fork possible. Our gravel fork is full carbon monoccoque with integrated brake cable to keep it away from snagging branches and flying mud. Our 44mm head tube improves control around the technical trail and in slippery mud, so you have the confidence to stay off the brake and enjoy the ride.
Rust inhibiting treatment
After being welded, filed and cleaned, our steel frames are dipped in a rust inhibiting treatment. The treatment provides a degree of protection, particularly inside the frame, against corrosion caused by acidic substances (including water). Read more
