Bolide F New Tt

Geometry is carried over from the prior Bolide F TT, with a four-size range built around aggressive, race-oriented fit numbers. Stack runs from 461mm to 507mm while reach spans 380mm to 430mm, which points to a low-front-end position suitable for experienced TT and triathlon riders who can sustain a narrow, aerodynamic posture. Effective top tube grows from 488mm to 545mm across the size range, while the seat tube angle stays fixed at 77 degrees in every size, reinforcing the bike’s purpose-built position around forward weight distribution and sustained efforts in the aerobars.

Handling numbers remain conservative and predictable for a modern TT bike. Head tube angle progresses from 72 degrees in the smallest size to 73 degrees in the two largest, balancing straight-line stability with manageable steering response. Chainstay length is fixed at a notably short 395mm across all sizes, which helps keep the bike compact and responsive under power, while BB drop ranges from 57mm to 62mm for a planted feel at speed. In practice, this is a geometry package aimed less at adaptability than at preserving a proven high-speed TT handling character.
