Originally conceived by Stelio Belletti, a continuous two year development period and two working prototypes have resulted in the third, and best, version: the SB/03.
The SB/03 is exclusively tailored to every rider. Stelbel have partnered with Columbus Tubi to create an efficient frame that combines rigidity and comfort.
Large diameter tubing coupled with Stelbel’s unique rear triangle design gives the frame optimum rigidity, increasing power transfer and road feel. More stiffness has been added thanks to the inclusion of a T47 bottom bracket. This oversized threaded bottom bracket standard eliminates any of the typical drawbacks associated with press fit systems.
One of the most distinguishing features of the SB/03 is the large, oval rear stays that measure 36x19mm and increase rear triangle rigidity which in turn improves power transmission to the wheel.
The chain stays are welded to signature Stelbel CR15 stainless steel dropouts, manufactured with CNC machining and specifically designed for non-tapered stays.
A tapered head tube has been adopted for maximum steering precision coupled with a 1.5″ fork and integrated headset. We can supply forks from Columbus Tubi, Enve, 3T and WR Compositi.
Each Stelbel frame is unique, exclusively made to measure and comes with custom geometry.
