The Vielo V+1 has been a long time in the making - a product of ideas, theories and extensive know-how gained from thirty years working with some of the world’s most coveted ultra-performance cycle brands.
Designed for British cyclist, the V+1 has not suffered compromises to meet the demands of global markets. Instead we have single-mindedly engineered the V+1 for riding on rough British roads plus off-road gravel tracks.
We think of it as a go anywhere speed machine. But in reality, it’s much more than that.
The V+1 is an exercise in painstaking attention to detail. A quest to find the perfect combination of compliance, stiffness and acceleration that helps British riders go where they want, as fast as they want.
The Engineers perspective
From the start we wanted to design a frame that could meet the demands of riding on poor road conditions and off-road riding. This meant that we needed lots of compliance, yet still be very stiff and have great acceleration.
I’m glad to say we have achieved this through two fundamental areas; first engineering the tube cross sections, which in itself is crucial to the carbon layup and also the behaviour properties when riding the bike.
For the rear triangle we chose very flat but wide chain stays and seat stays that provide a passive suspension. Although, I don’t like the idea of calling it suspension, it’s really providing a bit of travel. In combination with pre-bending the chain stays and especially the seat stays we can bring a lot of flexibility into the frame. Of course this needs to be controlled, so flex is vertical, not horizontal, which means it’s laterally very stiff to support aggressive riding and acceleration. It gives more control when cornering.
Also because the V+1 is a 1 by frame (single front sprocket), we have more freedom for rear tyre clearance and for engineering better, more suitable tube cross sections.
The CAD data provides a good idea how the design could turn out, but once the real results are in and it turns out the way we envisaged, it’s a really satisfying moment.
We have other nice features too. Like adapting the through axle system for the frame - only two turns is needed, it’s so fast to change a wheel. Also dropper post compatibility - because we don’t need a front derailleur we can use the left gear shift lever and run the cable entry into the frame, keeping things extremely neat. The V+1 is a very dedicated frame, exceeding it’s engineering goals and is perfect for what it was designed for - rough roads, off road, gravel riding, rough conditions.
I’m so happy with the result.
