Tech editor Nick Legan looks at Edvald Boasson Hagen's 2012 Paris-Roubaix bike, and the modified Team Sky Jaguars

Edvald Boasson Hagen's Dogma K
Edvald Boasson Hagen will be one of Team Sky’s protected riders for Paris-Roubaix. This Dogma K is the bike he’ll ride, though he’ll be trying Shimano’s C35 wheels during his reconn ride before Sunday. Photo: Nick Legan

Team Sky has used these Token-branded chain catchers for several years now. They must be working just fine. Boasson Hagen will likely ride a 53-42 chainring combo on his 175mm crankarms on Sunday. Photo: Nick Legan

One of Team Sky’s crack mechanics, Richard Lambert, washes bikes after the day’s training. He and colleague Gary were busy testing tire pressure drop when VN.com dropped by. We’d like to thank them for their time during such a busy period in the season. Photo: Nick Legan

Team Sky is experimenting with sealant inside its FMB tubulars for Sunday. “If it helps the riders get to the end of a secteur, maybe it doesn’t stop a puncture, but it does slow it down. If so, it’s worth a shot,” said Richard Lambert, one of Sky’s mechanics. Photo: Nick Legan

A couple Team Sky riders are using two sets of brake hoods for extra cushion. The mechanics turn them inside out and use a Dremel to remove all the shifter-locating plugs. Photo: Nick Legan

Yep, that’s two brake hoods, for extra comfort over the brutal cobbles of northern France. Photo: Nick Legan

To protect the engine and oil pan from the crowned peak of the cobbled secteurs, many teams install skid plates, like this one on Team Sky’s Jaguar. Photo: Nick Legan
