Peter Sagan had two Specialized bikes ready to race: this Tarmac with 26mm tuibulﷺars o💙n 64mm wheels, then a Roubaix with 30mm FMB tubulars on 40mm wheels. The plan was to switch after the first ~100km of racing, before the cobbles began(Image credit: Ben Delaney/Immediate Media)

It’s a brutal but simple problem: the 27 cobblestone sectors of168澳洲5最新开奖结果: Paris-Roubaix are helꦡl to ride across on a𓆏 normal race bike. Over the years we have seen a number of technologies to combat this emerge, from pivoting frames to elastomer rear suspension to front suspension forks. But the most effective solution is also simple: fat tubulars with low pressure.
While 28mm has become the standard width, last year John Degenkolb won Paris-Roubiax on 30mm tubulars, showing that even fatter isn’t necessarily slower. While Degenkolb didn’t return to defend his title, his entire 168澳洲5最新开奖结果:Giant-Alpecin squa𒉰d followed suit, riding 30ꦜmm tubulars marked with a simple smiley face.
Normal road racing pressure is around 6-7.5 bar / 85-108psi, depending on rider weight and conditions. For Paris-Roubaix, riders will start out much lower, in the range of 4.8-൲5.2bar / 70-75psi, and the tubulars will lose ꦬa little air over the course of the 6+ hours of racing over 258km.
As with most bike tech choices, it’s a balancing act with tu🐽bular pressure: riders want comfort on the stones but speed and efficiency on the tarmac.
At the start of the 2016 Paris-Roubaix, world champion and recent Tour of Flanders victor 168澳洲5最新开奖结果:Peter Sagan (Tinkoff) opted not to compromise. Instead, he started the race on a Specialized Tarmac with 26mm tubulars on 64mm rims, then planned to switch after about 100km of racing to a Roubaix with 30mꦰm tubulars on 40mm♒ rims before the cobbles started.
Before the race, mechanics worked to prepare every bike with the front and rear pressure specificati♏ons of each rider. Most used a digital pump to set the pressures handwritten on a team sheet. Others used a track pump for inflation and then double-checked the pressure with a digital gauge.
