Since its introduction, the Bora Ultra TT has accompanied cyclists of the highest caliber in winning international medals in time trials.

In 2017, despite such success, the Campagnolo road lenticular wheel sees further innovation, improving upon its main characteristics of low weight and extreme stiffness. The new Campagnolo Bora Ultra TT Tubular Rear Wheel in fact weighs nearly 111g less than the previous model and is 8% stiffer than the stiffest competitor’s wheel. The Campy Tech Lab has focused additionally on creating a product that meets the needs of time trial bike braking systems and the results are impressive.

Technologies

Ceramic Ultimate Level Technology (CULT) - Maximum Smoothness for Maximum Performance

Features

Wheel Developed for the time trial frame - extremely stiff structure further eliminates flex near the bottom bracket, namely where the rear brake is positioned on most time trial frames, thus avoiding any possible friction with the brake itself. 

Full high modulus carbon rim for tubular braking surface - newly developed full carbon rim uses carbon braking surface in an effort to add uniform braking performance in addition to saving weight. 

Brake pads made especially for carbon wheels - the new blend increases the brake performance on both dry and wet surfaces without increasing the wear and tear on the pad or wheel. 

Full carbon disc in a specially developed weave profile - extreme new design reduces profile on both drive and non-drive sides for an even slimmer and more aerodynamic design. 

Graphics featuring the “winged wheel” -  the legendary Campagnolo “Winged Wheel” logo identifies Campagnolo lenticular wheels that use the very latest carbon fiber technologies. 

Bearings with CULT Technology - the combination between the highest quality ceramic bearings and housing in special Cronitect steel. CULT makes the wheel nine times smoother than the standard system of steel bearings. 

Cup and Cone bearings - easy bearing adjustment – reduces the possibility of bearing play – precision operation – maintains performance over time. 

Lightweight and extremeley rigid aluminum hub construction cassette - compatibile with Campagnolo 10 and 11 speed cassettes as well as Shimano Inc. 9, 10, and 11 speed cassettes.

It shall be the end user's sole and full responsibility to choose - on a case by case basis - an adequate and correct rim-tyre-pressure combination, as well as to conduct all verifications necessary to ascertain the correctness and safety of such combination. Without prejudice to the above, and in order to ensure optimum rolling resistance, grip and, most importantly, safety, we recommend that the end user, in making his choice, also takes into consideration the recommended combinations of hooked rim width, tyre width and tyre pressure indicated in the chart set forth below.

Due to safety reasons, follow the information of the tyre manufacturer regarding minimum and maximum rim width to be used but always ensure that the combination is listed as possible in this table.
