Constructed to do many issues, like launch, nook, climb and descend, the brand new Colnago V4R highway bike is designed to do one factor: Win. And win it did, with 23 victories by 10 totally different riders on preproduction prototypes.
Designed with enter from UAE Emirates professional riders like Tadej Pogačar and Sofia Bertizzolo (UAE Group ADQ), the brand new bike will get up to date geometry, a extra sturdy layup, refined aerodynamics, and a one-piece bar-stem within the body module to provide them (and us) a race successful bike that’s additionally simple to journey all day lengthy. It’s additionally ever-so-slightly lighter…
The objective was to create a race bike that had the drag coefficient of an aero bike, to make the body stiffer and stronger, and to do all that with out including any weight.
Up entrance, a brand new CC.01 handlebar-and-stem unit saves a little bit of weight and improves aerodynamics by enhancing each its personal integration and in addition the interface with the body. A customized 3D-printed laptop mount (out there just for Wahoo BOLT V2 at launch) and smoother strains on the forks’ crown all helped cut back drag.
Cables now run internally, which required a bigger higher headset bearing and thus wider head tube, and the brand new lighter fork bumps clearance as much as 700x32mm tires. Regardless of all this, cautious shaping and the CC.01 cockpit left the general frontal space smaller than the V3R.
Contained in the headtube is a CeramicSpeed solid-lube headset, which they are saying is feasible as a result of the improved system stiffness places much less stress on the bearings. And that phrase “system” is essential, as a result of the statically examined stiffness of the V4R headtube is definitely 5-10% decrease than the V3R relying on body measurement.
Getting the suitable steadiness of stiffness and luxury got here from their inside “Actual Dynamic Stiffness” testing, which measured forces in two high-torque conditions – sprinting and seated climbing. In these two, system stiffness is 4% and 5% stiffer, respectively.
This allow them to use a lighter fork and enhance dealing with and luxury whereas nonetheless letting you effectively put out large watts.
The body itself will get barely heavier, however the lighter fork and cockpit elements assist the V4R’s full body module are available 47g lighter than the V3R module, which used a separate stem and handlebar.
Sizing has been up to date, with stack and attain figures rising in a extra linear trend.
Obtainable at launch solely in a V4Rs Group Version construct with ENVE 3.4 wheels, Shimano Dura-Ace Di2 group with energy meter, Prologo Scratch M5 Nack saddle, and Continental GP5000 tires for €15,260, with 5 colorways to select from. Body modules with bar/stem, seatpost and headset are €5,250.
