The Geometry
Below are Valdora geometry details for those in need of this information for assistance with fit. Valdora carbon triathlon frames are no longer in production as of 2024 but could return in the future.
Valdora triathlon geometry was perfected in 1998 under our first bike brand "bp Stealth" model AC-Tri which was later the Valdora AC-Tri (alloy compact tri frame). Once perfected, molds were opened and the all carbon PHX was born. The geometry was developed to provide an achievable aero position for the everyday triathlete. Professionals rode them and loved them but the geo was to allow a non pro to consistently hold the aero position for longer periods with superb handling. It only took the 'big' brands another 12+ years to figure this out and change their frame geometry.

VALDORA triathlon geometry is unlike any other. It was developed and tested in 2001 as the AC-Tri (alloy compact–triathlon) frame. Over the years it was tweaked to perfection before opening the molds for the PHX carbon frames in 2006. VALDORA has achieved an aero frame with triathlon specific angles that is responsive and climbs and descends with the ease of a road bike yet leaves the triathlete feeling fresh for the run. The unique configuration of adjustable seat tube angle (73 – 79 degrees for the PHX2), low bottom bracket, and taller head tube with a more aggressive angle is how this was achieved.
UK’s 220Triathlon publication wrote-
“The PHX tackled some real steep climbs and trouser-changingly scary descents almost with the ease of a regular road bike”…” Valdora is no slacker and really gives the impression that this is a triathlon machine. You find yourself in the perfect body position aboard the PHX, taking a lot of strain off the quads and shifting work to the hamstrings in preparation for the run leg”
Designed For Triathletes
A VALDORA frame will perform the same for a 125 lb. time trialist as a 230lb. former football player. The design factors that make Valdora frames superior for triathlon also make them superior for athletes of all ages, sizes and abilities. VALDORA frames are semi compact. The semi compact geometry makes the frame stiffer, stronger, and lighter. No loss of power from bottom bracket flex. Most riders will find that they can spend more time in the aerobars, in comfort, compared to other tri bikes. The angles and vibration absorbing carbon leave the triathlete fresh for the run. After all, triathlon is a three discipline sport.
Maximize Aerodynamics Through Comfort and Performance
Valdora frames are designed to maximize aerodynamics through comfort. The end result is no recognizable flex on the front or rear of the frame as well as no power loss when even the strongest of riders is hammering away. In fact, in many instances, riders are comfortable in the saddle and aerobars while climbing. Nothing like going up a slight grade in aero bars passing riders who are out of the saddle! Valdora bikes climb without losing power and descend without feeling scary. Valdora bikes are slippery fast and aero on the flats. Valdora geometry helps you to avoid being an aero helmet shark or a wind sail (triathletes sitting up every 10 minutes) due to neck, shoulder or lower back soreness, tightness, etc. Losing speed and power on the climbs, slowing on descents, not realizing optimum comfort in the aero position leaves the triathlete outside of the aero position.
