Vision Bike

Frequently Asked Questions

• How should I size a Vision PRSix or similar Vision triathlon/TT bike for the best fit?

  Start with your height and inseam to find a base frame size, then check standover clearance and cockpit length (saddle‑to‑bar reach) to dial in comfort in an aero position. A professional bike fit or test ride is strongly recommended since small changes in stem length, saddle position, and stack/ reach make a big difference on TT geometry. Make sure you can sustain the forward position without excessive neck or lower‑back strain.
• What drivetrain, wheel, and brake specs should I prioritize on a performance Vision road/TT bike?

  Look for mid‑ to high‑tier groupsets such as Shimano Ultegra or Di2 Ultegra for crisp shifting and reliability, paired with a cassette range (for example 11‑28) and compact or standard chainrings that match your course profiles. Choose 700c wheels shod with 23–28mm slick tires for low rolling resistance on pavement, and favor disc brakes for consistent stopping power and modulation in varied conditions. Also confirm wheel clearance, rotor compatibility, and whether the frame supports electronic shifting batteries and internal cable routing.
