At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything but we do try to look for weak points in any design.
This also means you can ride the Venturi past a gateway without worrying that your front wheel is about to take a slap from a crosswind. When it happens, the lack of twitchiness means the bike doesn't feel nervous or a handful. Orro designs all of its bikes in the UK and it has manged to reduce weight from the frame – by around 80g in this medium size – without sacrificing stiffness. An EPS latex core is now used in the mould, too, which makes sure that the frame is clean and smooth internally. That reduces excess material and therefore weight.
The frame and fork are designed around a 28mm tyre, with areas like the down tube and seat tube sitting very close to the tyres for that aerodynamic effect. The fork crown is integrated into the frame as well. The medium here has a 540mm top tube, and a head tube length of 143mm. As I said earlier, that head tube doesn't sit at as steep an angle as you'd expect, though, just 72 degrees in fact.
The Shimano builds are 105 , Ultegra and a limited-edition Signature model with Dura-Ace and Zipp 404 deep-section wheels among other extras. It's a web exclusive offering at £6,599.99. SRAM options include Rival eTap and Red . The handlebar and stem are both from Vision, with the alloy SMR Integrated used for the latter paired to the Trimax Aero bar.
Stiffness is good throughout, so there is no noticeable flex when you're out of the saddle when sprinting or climbing. The Venturi STC is a fast and efficient aero bike, that is surprisingly comfortable considering its tube profiles and stiffness. Did the bike feel stiff in the right places? Did any part of the bike feel too stiff or too flexible?
