Cervelo P-Series 105 TT Triathlon Bike 2021
Offering a wind-cheating design, high adjustability and high pedalling efficiency, the Cervelo P-Series 105 TT Triathlon Bike is a high-value option for any rider looking to beat their PB’s and peers when racing against the second hand.
The full carbon frameset is constructed from a lofty grade of carbon, and this material is moulded into aerodynamic tube profiles that take cues from Cervelo’s range-topping P5 bike to slip through the air with remarkably low levels of drag. This carbon frameset is also torsionally stiff and vertically compliant to improve power translation and to lower rider fatigue, respectively.
The vast adjustability of the Zipp handlebars and extensions ensure the rider can find their perfect position on the bike, while the Vision 35 Team wheelset is robust and reactive for a spritely but dependable performance. Shimano 105 gears change accurately with every click and the TRP mechanical disc brakes stop with aplomb within any weather conditions.
An aero water bottle, a top tube storage box and a rear bottle mount complement the already comprehensive build and encourage the rider to stay hydrated and fuelled at all times.
Highlights
- A high-value time trial or triathlon bike that is perfect for the athlete seeking speed and comfort in efforts against the clock
- The advanced carbon construction of the frameset allows the P-Series to be torsionally stiffer and lighter for faster climbing and better cornering
- The frameset tube profiles borrow their aerodynamic design from the range-topping P5 bike to lower drag markedly
- A highly adjustable cockpit allows any rider to dial in their perfect fit
- A 500ml aero bottle, 400ml top tube storage box and rear bottle mount care included as standard
- Vision Team 35 wheels are light and dependable
- Shimano 105 11-speed gear setup is accurate and reliable
- TRP mechanical disc brakes are powerful
