Uno-X is testing a new prototype lightweight race bike, which before any modifications weighs 6.9kg in a size small. The bike represents a refreshing departure from the aero bike hegemony, with relatively traditional tube shapes used throughout. There's more to be shaved here, according to the team mechanics. Ashley Quinlan / Our Media That said, the head tube features some aerodynamic profiling, as does the upper portion of the seat tube. While still aero profiled, the front end looks quite traditional. Ashley Quinlan / Our Media An aero seatpost is also used, but topped with a lightweight clamp design. This features a hollow carbon cradle fastened in place by two bolts. The seatpost clamp is a neat design. Ashley Quinlan / Our Media Below this, the seat stays are strikingly slim, a common tactic used by brands to lower weight while increasing frame compliance. Tobias Johannessen is set to test this one. Ashley Quinlan / Our Media Tyre clearance also appears competitive with the growing number of race bikes with space reaching into the mid-thirty millimetre region, albeit the team mechanics wouldnt confirm the frames official limit. Continental's time trial tyres should offer low rolling resistance and weight. Ashley Quinlan / Our Media This bike, belonging to Tobias Johannessen, was running 28mm Continental Grand Prix 5000 TT TR tyres. These are said to be an optimal size for the 38mm-deep DT Swiss ARC 1100, while the choice of a 28mm tyre will be lighter than the increasingly normal-choice 30mm rubber. The choice of 28mm rubber indicates a focus on weight, too. Ashley Quinlan / Our Media Up front, the fork crown is notably U-shaped with prominent shoulders. Alongside offering increased tyre clearance, this could be assisting with shaping airflow before it hits the riders legs. The fork crown is U-shaped, which might confer some aero benefit alongside tyre clearance. Ashley Quinlan / Our Media While less impactful when climbing a mountain at slower speeds, aerodynamics will have a role to play in descending speed should a competitor (or Johannessen) attack over the crest of a climb, this efficiency will surely be appreciated when countering. We'll wait to find out if this bike is an updated Falcn RS or something else. Ashley Quinlan / Our Media Its unclear what this new bike will be called both the UCI and Ridleys stickers stat prototype but the family resemblance to the existing Falcn RS all-round race bike is strong. The cockpit appears standard, Ridley clearly preferring a simple setup to work with its Forza components arm. Ashley Quinlan / Our Media The relative lack of deeper-section aero tubes would suggest Ridley is looking to keep this new bike and the Noah Fast set distinctly apart from one another, rather than looking to merge the Falcn RS and Noah Fast into an all-in-one platform. Well deliver the official word from Ridley on this new bike when have it.
