namics
The request to have a bike easy to assemble in pre-race phases and easy to disassemble
in the post-race has come not only from AM, but also from PRO. In fact, in a physically
and mentally wearing race like the triathlon it is important not to waste nervous energy
in the preparation of the mechanical mean. This request was seriously taken into consid-
eration and guided many engineering choices of the project.
In the same way the input to improve comfort and handling feeling was well considered.
A specific TT is designed for TT stages (max 50Km) and generally flat. Triathlon and Iron-
man races are longer (even 180Km) and can find many different uphill and downhill along
the way, so a specific TR+ must take into consideration.

In details the areas where Pinarello Lab focus its attention are: of the head set.
2 - BOTTOM BRAKET: moved downward by 8mm in comparison to Bolide TT.
This improves comfort especially when getting on the saddle. In addition the overall
center of mass is downward improving riding stability and aerodynamic efficiency of the
bike.
3 - SEAT TUBE ANGLE: moved forward to 78°. In combination with the seat-
post straight the position becomes particularly advanced, ensuring the best thrust on
the pedals. Two other seatpost versions will be available with retractions of -25mm and
-50mm. In this way, every athletes can find the most congenial position for his ride.

4 - CHAINSTAY: As on the Bolide TT the length of the Chainstay remained
395mm, that is extremely short. This guarantees an excellent transfer of power to the
5 wheel and agility in the bursts out of the curve
1 5 - TYRE CLEARANCE: Bolide TR+ is designed for allowed a max tyre 700x28mm
and a rim width of max 30mm. This ensures the compatibility of the frame with modern
Triathlon wheels specifically designed to optimize aerodynamics.

b. AERODYNAMICS
Once the frame geometry was defined, the development work focused on the aero-
dynamic aspect. The clear target was to keep aero performances of the Bolide TT but
adapted to the Triathlon needs. Several hours on CFD simulator were performed to op-
timized the Bolide TR+ shape.
The starting points for fluid dynamics analysis were:
- Bolide TT shape as baseline. Bolide TT aerodynamic was used as starting
point and as benchmark to design the Bolide TR+ frame shape.
- No UCI Limit. Bolide TR+ is following ITU (International Triathlon Union) rules
Once the initial parameters and the boundary conditions were defined, the aerodynamic

there can be considerable differences in the results if the analysis is carried out by stud-

- Kona wind specifications. To define the wind parameters to be used in the CFD
analysis, it was decided to consider the average wind values present at Kona (in terms
of speed and angle of attack). The aerodynamic profile of the frame was then optimized
for these conditions but then evaluated that it had no contraindications in case the wind
parameters were different.

The front cover, that integrates the routing of the front brake hose, is integrated with

The decision on the type of fuel storage to be done and on their position has been taken
following the feedbacks of the pro and am athletes. Everything was validate in several
CFD simulation sessions. For example we exclude from the beginning to have an inte-

surface has a negative influence on aerodynamic and riding feeling during crosswind.
