Dan Bigham used an unreleased Pinarello that resembles a track-adapted Bolide F in his successful UCI Hour Men’s Record attempt.

The Ineos Grenadiers performance engineer took on Victor Campenaerts’ mark of 55.089km at the Tissot Velodrome in Grenchen, Switzerland.

The 30-year-old is the British Hour Record holder, having beaten Sir Bradley Wiggins’ distance by riding 54.723km on the Swiss track in October 2021.

Bigham reportedly said after that record-breaking ride he would need just seven watts to overtake the Belgian Campenaerts – a WorldTour racer with Lotto Soudal.

Speaking after toppling off his bike in exhaustion, a triumphant Bigham said: “That was my best-paced hour by far. “I was a bit ahead at each split. I had to do 16.0 [second laps] for the second half.

“I haven’t ridden 16.0s for half an hour before. It was pretty epic.”

“I had an ungodly amount of support from Ineos. Not just in terms of the equipment – I can go on all day about CdA – but in terms of physiology, thermal acclimatisation and nutrition.

“They have stepped up the support and have been second to none.”

Modified for the track

Bigham’s bike bears a close resemblance to Team Ineos Grenadiers’ recently unveiled Pinarello Bolide F time trial bike.

This means a swap from the Argon 18 Electron Pro he rode in October.

Incidentally, Bigham’s partner Joss Lowden used that bike to set the UCI Women’s Hour Record. Ellen Van Dijk then surpassed Lowden’s distance on a custom Trek Speed Concept, accumulating 49.254km in May this year.

Unlike when riding for the giant-slaying Huub-Wattbike track team, Bigham’s tech choices were largely from Team Ineos Grenadiers’ sponsors and suppliers.

These include Kask for helmets, Bioracer for clothing, Princeton Carbonworks for wheels and Muc-Off for chain lube.

Bigham told BikeRadar he would wear a Kask Mistral helmet. This continues a trend of Ineos riders using big helmets and visors for aerodynamic purposes seen at the Tour de France.

As a result, Bigham wore a Bioracer Katana skinsuit rather than a Vorteq outfit he wore when setting the British Record.

Bioracer Epic shoe covers went over Nimbl Expect shoes.

As far as we’re aware, this is the first-hour record taken aboard anything other than tubular tyres.

He used Princeton Track Specials wheels wrapped in Continental GP5000 TT tyres and fitted a Most Custom 3D basebar and extensions.

Speaking to BikeRadar, Bigham wouldn’t disclose his tyre type or pressure, saying: “I don’t want to give too many secrets away.

“But they will be higher than some people might expect.”
