Pro bike: Greg Van Avermaet's BMC GranFondo GF01

Kinks and angles for the broken cobbles

The addition of sports director Allan Pieper to BMC has given the team newfound focus this season. The more finely honed single-leader strategy during races has already paid dividends in the early season but according to team mechanic Ian Sherburne, the sharp Aussie has also instilled a more methodical approach to equipment testing, as evidenced on the bike of Greg Van Avermaet.

Pieper clued BikeRadar in on two pieces of equipment insight gleaned during off-season testing. For one, Shimano's 50mm-deep Dura-Ace carbon wheels actually absorb more road imperfections than its 35mm option – and in most wind conditions, they're appreciably faster, too. Secondly, while average endurance-type riders might prize the softer ride that the stock BMC CompliancePost carbon seatpost provides, the unforgivingly harsh Paris-Roubaix cobbles prompted the team to instead add 50g of material to better deal with the big hits.

More flex comes from the generous amount of 27.2mm-diameter seatpost sticking out of the frame. aluminum number plate holders are secured to the back of the seatpost with industrial-strength double-sided foam tape: more flex comes from the generous amount of 27.2mm-diameter seatpost sticking out of the frame. aluminum number plate holders are secured to the back of the seatpost with industrial-strength double-sided foam tape - James Huang/Future Publishing

Speaking of which, Van Avermaet's BMC GranFondo GF01 frameset also mimics that more performance-driven ride characteristic. Unlike many bikes of its ilk, the GF01 doesn't deliver the creamy ride that some might expect – and in fact, its massive lower half can sometimes feel surprisingly stout. That said, its flex pattern is tuned more for faster and more intense bumps in the road – just as would have been the case last Sunday.

Pieper says that the GF01's modified geometry relative to the team's standard SLR01 model also makes it a smarter choice for Paris-Roubaix. The longer wheelbase and slightly relaxed front end makes for a more stable platform that can better handle the bumps. According to Pieper, it's also more forgiving toward the end of the race when the totally shelled riders might find a typical race bike a little too twitchy.

More importantly, there's room in the GF01 for the huge 27mm-wide handmade cotton tubular tires used by Van Avermaet and his teammates, with fine file treads that wrap nearly all the way down the sidewalls. While BMC is sponsored by Continental, the ones used at Paris-Roubaix clearly didn't come out of Germany. We can't identify for certain the manufacturer – and of course, the team wouldn't talk about it – but given the tread pattern and the 'Made in Thailand' lettering molded into the rubber, Challenge seems like a reasonably safe bet.

The rest of Van Avermaet's setup closely followed that of many other top Paris-Roubaix contenders, including the Shimano Dura-Ace Di2 9070 electronic group with a full complement of satellite shifter buttons and big gears tailor-made for the flat course. Other component highlights include an SRM power meter, a 3T forged aluminum stem and single-wrapped traditional-bend carbon bar, a fi'zi:k Antares with carbon rails, Elite Sior Mio cages, and Dura-Ace carbon-bodied SPD-SL pedals.

The exit point for the shimano dura-ace di2 wire is so close to the rear derailleur that there's no need for an additional zip tie to secure it in place. greg van avermaet (bmc) ran a relatively tight 11-25t cassette on sunday and put the power down through a set of carbon-bodied dura-ace pedals: the exit point for the shimano dura-ace di2 wire is so close to the rear derailleur that there's no need for an additional zip tie to secure it in place. greg van avermaet (bmc) ran a relatively tight 11-25t cassette on sunday and put the power down through a set of carbon-bodied dura-ace pedals - James Huang/Future Publishing

Total weight with the SRM PowerControl 7 computer head (but no water bottles) is 7.54kg (16.62lb).
