Jack Bobridge’s Cervelo T4 world hour record bike

A close-up look at the Australian’s purpose-built ride

On 31 January, Australian Jack Bobridge will be the next person to take on the world hour record. Swiss rider Matthias Brändle (IAM Cycling) currently holds the record at 51.852km.

Bobridge put in a strong performance at the 2015 Tour Down Under, including winning the first stage, and appears to be in fantastic form to take to the track. Now riding for Australian continental team Budget Forklifts, Bobridge is once again on Cervélo, having previously ridden the brand with team Garmin-Cervélo in 2011.

For the hour effort, Bobridge will ride a Cervélo T4 built with an impressive list of components that’s more than worthy of the current 4,000m world record holder.

We managed to snap photos of this special ride during the Tour Down Under, although we were unable to take our usual pro bike measurements and in-depth details. We suspect many measurements will be close to those of his Cervélo S3 road bike we looked at last week though.

The Cervélo T4 is a track-specific model that combines the aerodynamic knowledge learned from the P series, with a simpler fixed-gear and brakeless setup.

The wheels are Lightweight Runkurs disc wheels from Germany. Like anything from Lightweight, these are insanely light and insanely expensive.

The 3t cockpit is specific to the cervélo p5. the extension bars are rather budget tranzx:

The 3T handlebar and stem are exclusive to the Cervélo P5

Bobridge will sit on a Selle Italia SLR XP saddle for the hour, while a 3T Aduro integrated stem and bar setup (from a Cervélo P5) with TranzX extension bars will keep the 25-year-old on track.

Our photos show a SRM Campagnolo 11-speed, however, the world hour record doesn’t allow the rider to look at data during the attempt, so Bobridge will use a slippery Campagnolo Bora TT crankset with an aero carbon chainring. A 1/8in Izumi chain is pictured, although we’ve since been told that Bobridge will swap to a 3/32in rear cog and 11-speed chain. The gearing ratio he’ll use is unknown.
