44mm head tube with Chris King headset
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. A Chris King headset is included with all stainless frameset purchases.
Thru-axles not only keep the disc running straight, but also improve the stiffness of the frame. Paired with our monocoque carbon gravel race fork, the Bivio Gravel delivers stable, predictable steering on tough terrain.
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.
Your design, your colours, no extra cost
Attention to detail and design touches make the Acciaio Stainless a beautiful piece. There is no additional charge for extra colours, multiple polished sections or unique designs. Our designers work alongside you to bring the Acciaio Stainless to life. From polished logos and stays to fades, there are no hidden costs; you can have your frame painted the way you want it. Need rack mounts or extra bottle cage bosses? There is no additional charge.
XCr stainless, the ultimate steel
Unlike other stainless steel tubesets, Columbus uses seamless stainless steel, which enables the tube walls to be drawn extremely thin at just 0.4mm. This keeps the weight low whilst having a higher stiffness to weight ratio than Titanium. It is corrosion resistant, too.
