Put simply, the Dean is among the very fastest tri bikes on the planet. Ridley’s technologies create the distinct, sculpted, wind-cheating designs that can save competitors time. This is achieved partly via careful molded-in F-surface technology and internal cable routing – both of which create some of the cleanest laminar flows on any tri bike available, particularly in real-world riding situations. Every rider will appreciate the custom stack-and-reach, making the Dean fit everyone with the lowest possible riding position.

  • F-Surface paint technology reduces drag by 4.1% by increasing laminar flow
  • full carbon head tube with angular contact bearings
  • oversized PF30 bottom bracket increasing stiffness
  • optimized tube shapes for superior aerodynamic performance at all yaw angles
  • cutouts that make the distance between the frame and the wheels as narrow as possible reducing turbulence
  • integrated cockpit has internal cabling
  • ready for integration with all electronic shifting systems batteries which are hidden either in the seat post (Shimano Di2) or just behind the stem (Campagnolo EPS)
  • adjustable TT aero seat post with large for aft adjustment at the saddle rail allowing optimal seating position over the BB shell
  • integrated seat post clamp that fi rmly holds the seat post in place without poking out in to the wind
  • wider rear triangle allows easy fitment of wider rims and tires
  • vertical dropouts makes it simple to change and center the rear wheel while keeping the optimal position behind the seat tube

Instrukcja mierzenia

Aby dokładnie ustalić rozmiar niezbędny do zamówienia roweru lub ramy czasowej/triathlonowej RIDLEY należy zmierzyć się i porównać wymiary swojego ciała z wymiarami podanymi w tabeli.

Pomiary wykonujemy taśmą centymetrową stojąc w pozycji wyprostowanej i swobodnie oddychając, najlepiej w stroju kolarskim lub bieliźnie.

  1. Długość nogi - mierzymy w linii prostej od kroku (górna płaszczyzna poziomicy lub innego przedmiotu) do podłoża stojąc bez obuwia ze stopami ustawionymi ok. 20 cm od siebie.
  2. Wzrost - mierzymy w linii prostej od wierzchołka głowy do podłoża stojąc bez obuwia, ze złączonymi stopami.
