Vielo V+1 UDG with Shimano GRX Di2 -  Online Exclusive.

The age old question ... are you Shimano, SRAM or Campagnolo ? We know its much like your football team, once you've made a choice you're loyal for life.

We're a big fan of Shimano's Di2 GRX group set. The new style and shape of the hoods are a beautiful thing and the Di2 shifting and functionality is renowned for its reliability and performance. So we've come up with an Online exclusive GRX specification for all the lovers of Shimano gravel bikes.

The V+1 UDG frame comes from the same mold as the V+1 UD. The only difference? the carbon layup we use is more economical meaning it's slightly heavier but also reduces the price. In the end, the difference between the frames is only an extra 220g. Crucially the ride performance and characteristics are the same.

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.

About this bike

This is the V+1 UDG frame in Dusk Blue, with light blue and orange details. The UDG frame 880g for the frame and 400g for the fork. We've built the bike with a complete Shimano GRX Di2 group set, teamed with DT Swiss GR1600 wheels with WTB Resolute Tan Wall tyres. We've finished the bike with the bling it deserves, Hope RX4 brake calipers with piston caps colour matched to the Orange frame details. The internal battery is charged via the bar end cap charging port.

It's the latest bike in the Vielo family, but features the same ride performance and charm as the V+1 UD reviews you've read.

8/10 Road.cc  "Verdict: Smooth and composed road plus bike from a British brand with exceptional attention to detail"

The Vielo V+1 UDG Rival Edition is a smooth and stable road plus bike that's a lot of fun whether you're riding smooth tarmac or broken tracks. It's not quite as light as the original V+1 that we reviewed last year, but the difference is small and it exhibits that same assured performance and attention to detail.
