Columbus Niobium tubing
best in the world

Track Bike frame and fork only. Made from Columbus SL Niobium tubing, hand brazed into investment cast lugs. The top of the line material from Italy’s best tubing manufacturer, SL Niobium is a special micro alloyed chromoly steel blend, employing the latest chemical technology in its refined metallurgy. Niobium steel alloys are also required in rocket and jet engines, and in superconducting equipment like MRI machines. It is the strongest most durable steel possible, meaning that less needs to be used to make the strongest lightest steel bicycle frame possible. This frame weighs 1.59 kilograms (3.50 lbs) for the 47cm size.
