Colnago has a number of top-tier carbon fibre race bikes in its line-up. There’s the Italian-made lugged-construction C64, the latest in the iconic C-series. There’s the Concept, the company’s answer to an aero racer. And there’s the V series, an all-round racer that uses a monocoque construction method (like almost every other carbon race bike at the pro level, excluding the C64).
It’s the last of these that Colnago has just updated to the company’s highest stiffness-to-weight ratio bike. The V3Rs and V3Rs Disc replace the V2r, a bike that has commonly been the pick for UAE Team Emirates and the now-defunct Wiggle-High5 women’s race team. And like a scene out of The Walking Dead, the V3r joins a long line of similar-looking, do-it-all, lightweight, stiff, compliant and semi-aero race bikes each of which is hungry for your attention.
What’s new? Just as we’ve seen with Wilier, Scott and Cannondale, the V3Rs offers stealthy cable integration, dropped seatstays, increased tyre clearance and an overhauled geometry. And while the hefty cable integration is kept for the disc-brake version, there is a direct-mount rim brake version, as well.
The Colnago V3rs Somewhat simpler, the rim brake version offers direct-mount brakes and brake cable routing that’s not guided through the stem or headtube. Compared to the V2-r, the new frame is stiffer by 12% at the rear and 6% at the front, all while dropping some 50g of frame weight. A raw, unpainted, 52cm disc-version of the V3Rs weighed in at 790g, with an uncut fork at 390g.
However, at a guess, the cable integration found in the disc-version will add back any weight saved. And while Colnago hasn’t said by how much, the new frame is apparently more compliant, too. Part of that may be the overhauled carbon layup, or dropped seatstays allowing more seat tube flex. Another reason may be the new headset that offers surrounding composite material designed to aid in compliance — a feature borrowed from Colnago’s Concept and C64 bikes.
Colnago V3rs The geometry has been overhauled, but it remains race-orientated. Much like the new Scott Addict, the V3r is optimised for 28c tyres (it can apparently squeeze in 30c, although Colnago’s own literature says otherwise), and the geometry and fork have been revamped to retain a race bike fit and feel. For this, the bottom bracket has been lowered and the fork length increased, matched with a shorter head tube. With a sloping geometry, the stack and reach figures are now more linear across the eight frame sizes, as well.
While Colnago has made no specific claims about the aerodynamic performance of the V3Rs, it’s clear that with an integrated cockpit, dropped seatstays and seemingly truncated tube shapes, it’ll be faster than its predecessor. That fully integrated cabling is exclusive to the disc-version, and uses Colnago’s own stem and a special threaded fork steerer tube to route both the hydraulic hoses and electronic shift wires through the stem and directly into the head tube. Colnago has reworked the integrated seat post binder, too, said to be smaller and more secure than what’s found in the V2r and C64. It holds Colnago’s own version of a D-shaped seatpost.
The Colnago V3Rs is available in 8 sloping sizes and 9 colors. For more information we can be reached at 503-699-8665 or info@Lakeside-Bikes.com
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.
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).
To reach a new weight target of 790 grams for the size 50s in the raw disc version (including the metal components) we 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.
