Introduced last year as a team only time trial bike, Scott has announced the consumer versions of their Plasma 3.
Shown above in team spec is time trial model, and there will be two triathlon versions as well. The main difference between them will be the stem: The TT version gets the fully integrated and inline stem shown on the HTC-Columbia team bike above, and the triathlon models will have more adjustable stems that rise slightly above the top tube.
Despite the dramatic aerodynamic shaping, Scott says the bike meets all UCI 3:1 rules, so whether you’re racing UCI or ITU events, you should be fine on either model.
More pics and specs, including the tri bikes, after the break…
Shown above is the triathlon bike, which is currently being raced by Scott’s sponsored pro Normann Stadler. By the numbers:
- Drag optimized aerodynamic profile on all tube sections
- Fully integrated frame and stem system
- “Twin Turbo” oversized chainstays
- Adjustable seatpost in custom aero shape to match frame
Above is the triathlon version, which comes with either 75mm or 90mm length stems, both with 40mm rise and both have internal cable routing. Additional rise can be achieved with aero bars.
The TT version gets the streamlined, lower stem.
The seatpost uses a slide-rule style clamp for a wide range of fore-aft adjustability from 73º to a virtually upright 80º. The TT version will have updated graphics, this is the 2010 team bike shown, but the frame is the same.
Viewed head on, it’s pretty slim.
The TT version will ship before the tri bikes, and it’ll come with Shimano’s electric Dura-Ace Di2.
The chainstays are tall and thick at the front, then curve into wings at the rear as they flare out to the dropouts.
Trick rear brake placement and cable routing look great in person and put the brake in an otherwise turbulent area, reducing it’s overall impact on aerodynamics despite not being fully concealed like some other TT/Tri bikes.
The flat bottom and shaping of the bottom bracket area mimics the TT stem’s nose cone.
The seat stays are aero shaped but plenty stout.
What a light crosswind would see.
