V1-R Aeroshape

Aeroshape

All of the V1-R’s tubes, including the fork blades and the seat stays, have a special shape optimized in the wind tunnel to make the V1 even faster. The profiles are derived from the NACA (set of foils, and have been heavily revised to be optimized for the speed of a bicycle then truncated to better respond to the demands of the UCI regulations and structural requirements. Unlike the K-Zero, our benchmark for frame aerodynamics, the V1-R has truncated tube profiles, i.e. with a drop-shaped front leading edge and a cut tail. Colnago strongly believes that a bicycle requires a balance between the aerodynamic and structural strength, particularly important is the lateral stiffness of a frame, and this is strongly tied to the thickness dimensions of tube sections. The main characteristic of this cut-off profile is the increased lateral stiffness, compared to the equivalent full profile, thanks to the action of the rear plane.

V1-R fork

Fork

The V1-R’s fork is also a new concept, designed and structured to support the integrated front brake body. It has a double hole to accommodate the dual pivot system for direct mounting. The brake is thus more rigid, powerful, and aerodynamic. The design also incorporates the shapes of the other tubes with the truncated profiles. The base measures 1 “1/4, while the remainder is 1 1/8”. A valuable detail is the conical carbon fiber head, on which is located the headset bearing. Tolerances allow the mounting of tires up to a maximum size of 28 mm. Also; as with all Colnago forks, the dropouts are made of aluminum.

V1-R Brakes

Brakes

One of the most striking features of the V1-R is the adoption of a new standard for the braking system. The choice was made to use direct mount brakes, first developed by Shimano for the new Dura-Ace. The main advantage of this brake is a better integration, both structural and aerodynamic, with the frame and fork. In terms of performance, this translates into a system that is stiffer (and therefore more powerful), lighter, and with cleaner aesthetics. Shimano offers these new brakes in the 105, Ultegra and Dura-Ace series. For the customer wishing to use SRAM or Campagnolo components, we have also developed our own brake, which will be available with the frame.

V1-R Carbon frame dropouts

Carbon Frame Dropouts

Another major innovation found on the V1-R is represented by the use of carbon fiber monocoque dropouts and an internal replaceable derailleur hanger. The advantage in terms of strength and weight are significant compared to the equivalent solution adopted in the past on the M10. Inside the right dropout there is the hole for the rear derailleur cable, suited for both mechanical and electronic groupset.

V1-r disc brakes

Disc brakes

REAR - The housing for the disc was obtained directly from the mold, without sacrificing the full carbon dropout, one of the most important characteristics of V1-R. The threaded insert is lightweight and rigid and can rely on a self-centering clamping system. This makes installation and proper adjustment of the rear caliper much easier.
FRONT - For V1-R Colnago has developed a new fork. The most noticeable change is the new hexlock15 locking system thru axle system, based on the Manitou proprietary design. In order to remove the wheel, you just have to open the quick release and then turn it 90°, that’s it . This system is both stiffer and faster to engage than a standard QR9 axle. The thru axle design does not allow for independent fork leg movement, improves tracking while braking and has more precise handling. The passage of the cable is inside the left leg. The fork dropout with open QR9 will still be available.

Bottom bracket

Bottom bracekt

To increase the rigidity of this portion of the frame, without increasing the thickness of the tube walls and, consequently, frame weight, the V1-r uses tubes with larger sections. Therefore, the width of the bottom bracket area has also been increased. Colnago assessed all the standards currently on the market prior to this design’s debut. The “BSA” standard is good for reliability, but is too old compared to the technical evolution used to develop the V1-r. None of the PressFit systems available met the needs of reliability and durability required by the V1-r. Reluctant to compromise, Colnago has decided to take the best of both technical solutions – the reliability and practicality of a threaded bottom bracket (BSA), and the width and rigidity which characterizes the standard press-fit. So, Colnago introduced the Threadfit82.5 patented proprietary standard. Compatible with all the Pressfit 86.5 BB versions, the Threadfit82.5 adds two new cups that are easily removable – significantly adding to the longevity of the frame.

Seatpost

Seatpost

For the maximum integration and aerodynamics, we offer the new V1-R with a special, dedicated seatpost. Using the proven forged aluminium head of the models currently in production, we proceeded to design and build a tube of small diameter (approx. 27.2 mm) for maximum comfort and aerodynamic profile (also a truncated profile) to ensure maximum penetration of the air.

V1-r Aeroshape

Aeroshape

All the tube shapes on this frame, including the fork legs and the rear triangle, have been tested and studied in the wind tunnel to minimize drag.

From a structural point of view, the best shapes for bicycle frame tubes have been circular or polygonal shaped, as they are able to maximize the flexural and torsional rigidity regardless of frame size. From the aerodynamic point of view, the best sections have a “drop” shape: they minimize wind resistance with the same front footprint, when the apparent wind direction lies in the plane of the center line of the frame. This condition occurs in the absence of side wind or, with good approximation (4-8 ° of rotation), when the speed created by the cyclist is much higher than that of the side wind – for instance, during a time trial race. By design, the tubes of the Colnago K.Zero time trial frame sections are characterized by this “drop” shape. In the case of low speed riding with the presence of side wind, the apparent wind direction is rotated with respect to the centerline plane of the frame. Even uphill, with a strong side wind the apparent wind direction can be rotated by almost 90° with respect to the centerline plane. In these cases, a “drop” profile is no more efficient as you generate a phenomena of stall and turbulence which increases resistance on the front and side of the bike. In such situations, the optimized solution, which maximizes the flexural and torsional rigidity and at the same time minimizes aerodynamic drag and crosswind, is represented by the truncated sections of the tubes. It’s these that are utilized in the Colnago V1-r frame.
