As with the tubulars, Specialized has been pushing Quick Step to ride its wheels for years. For 2015, that became a reality

28 is the magic number for Paris-Roubaix. Although a clincher was one of Specialized's first products back in the day, getting WorldTour teams on the company's tubulars is a relatively new thing

On Friday Niki Terpstra and his Etixx-Quick Step teammates rode critical sectors of Sunday's Paris-Roubaix course, a longstanding reconnaissance tradition made special for the returning champion.

"The feelings today were really good on the cobblestones," Terpstra said of riding his Specialized S-Works Roubaix. "It was nice to be back. I have good memories of course. It was good to get a feel for Sunday."

In 2014, Terpstra was riding in support of team leader and multi-time Paris-Robuaix winner Tom Boonen. Boonen is out with an injury this year.

This year Terpstra is co-leader of the team along with cyclocross star Zdenek Stybar and Stijn Vandenbergh.

Standing 186cm/6'1", Terpstra has some similarly large figures for his Roubaix bike: 28mm Specialized tubulars, a 155mm-width Specialized Chicane saddle, 177.5mm FSA K-Force Light cranks, and 53/46 FSA chainrings.

Take a look at the gallery above for a closer look at Terpstra's Roubaix for Paris-Roubaix. 

The K-Edge number plate will be holding the enviable #1 come Sunday, as Terpstra trusts his 28mm Specialized tubulars to see him through the pavé
