The V3Rs is fast on long climbs; in windy plains; on big Tours; in stages and in the most demanding Granfondo. While retaining some details from the two frames that preceded it, V1-r and V2-r, the V3Rs design has profoundly changed to align with some standards that have been consolidated in recent years, not least the possibility of mounting larger tyres – up to 28 inches. It’s extremely clean and boasts excellent aerodynamic qualities together with an unprecedented lightness. V3Rs is available in eight sizes from 42s through to 58s and in two versions, direct mount rim brakes and disc brakes.
To reach a new weight target of 790 grams for the size 50s in the raw disc version (including the metal components) Colnago used a new type of carbon fibre that allowed Colnago to significantly increase the rigidity to lateral flexions. The new V3Rs, compared to the V2-r, has a 12% higher rigidity in the rear compartment and 6% in the front head tube area. The ability to absorb vertical shocks has improved significantly, which translates into greater comfort.
Completely new and redesigned, the V3Rs fork is much lighter compared to that of the V2-r. Its raw weight (uncut) corresponds to 390 grams, TFS integrated steerer thread included. In a 50s size, which we can consider an average size, the cut fork can weigh just 340 grams. The new shape with concave sheaths in the upper part (front view) optimizes the wheel passage allowing the use of wide tyres (28c), along with comfort and lateral rigidity.
While the rim brake version is based on the use of dual pivot brakes with direct mounting and external cable routing, the disc version uses the exclusive TFS Integrated fork system. The cables pass entirely, internally to the Colnago Sr9 stem and then through the fork steerer. The frame is thus extremely clean and technically more aerodynamic.
Much of the effort has been concentrated in this area of the frame, both to reduce the overall weight of the locking system and to increase its functionality, power and safety. The new locking system is therefore smaller if compared to that of the V2-r and C64, integrated into the frame and allows a greater modulation in tightening.
What is the point of making a light bike if you can’t ride it effectively? For this reason the geometry has been completely redesigned. The main features are the shorter head tube, the longer fork and a greater balance across all eight size options. The height of the bottom bracket has also been changed, it is lower, to improve the driveability of the bicycle with increased tyres (28c).
