Tradition vs. Technology

Paris Roubaix is a race steeped in tradition. Every chapter in the race's history sees common threads woven throughout, and this lays the foundation for Paris Roubaix's timeless appeal. Almost every other race in the PRO calendar has been touched by the hand of modern bicycle technologies. A look at the Tour de France reveals high-tech machines taking advantage of the most advanced technologies available to the manufacturing world—an engineer's showcase of the thinnest, lightest, and fastest—an envelope pushed so far that the UCI has a specific rule in place in an attempt to keep things safe.

The race's tradition extends far beyond the route, the stones, or the concrete showers, rather the tradition extends into the mindset of the riders themselves. Many understand that the race is comprised of unpredictable events and the fastest way to a win is to limit as many unknowns as possible.

A walk though the start village in Compiègne illustrates the different strategies of the teams. Some teams and riders opt for cantilever brakes, others the standard road calipers. Some go for double tape, the 23, 25, 27, 28mm tires, and suspension forks. The list of Roubaix-specific accoutrement is as long as the line at the espresso tents. However, there is one gear selection that remains almost unanimous among teams: the decision to ride "traditional wheels".

The term "traditional" is used by many of the teams to describe the traditional, 32-hole hub, three cross spoke pattern and "low profile" rim with a tubular tire glued to it. Over the years and with all the developments in wheel technology, it is fascinating that the wheel choice for Roubaix remains a "low-tech" option.

Undoubtedly, the high-tech players are in hot pursuit of a seat at the Roubaix table. Zipp, for example, has been hard at work developing a deep section carbon wheel capable of delivering all the performance characteristics against the wind, while continuing to be able to handle the stones. Most recently, the CSC team has been spotted at Flanders with a deep section, rear wheel, and a traditional front.

(BKW has spent some time speaking with the folks at Zipp; stay tuned for a future post featuring Zipp's experiences at the Classics and the future of a deep-section carbon Roubaix wheel.)

For more information on the traditional wheel approach, we placed a call to BKW friend and PRO mechanic George Noyes. As a recap, George turned wrenches for cycling's best and did his time in the trenches for 7-Eleven, Motorola, Cofidis, and Mapei. George has built enough wheels in his career to fill a stadium and included in his builds are wheels that carried the Lion himself to victory at Roubaix.

When speaking about the traditional wheel style with George, it becomes immediately evident that he remains passionate about wheel building and he respects the love and attention to detail so common among traditionally constructed wheels. Although the options for wheel building seem endless, the builds at Roubaix all seem to be alike.

A wheel for Roubaix needs to deliver overall durability, lateral stiffness, and the ability to absorb impact. George confirmed that in the years before deep section, carbon wheels, mechanics often built the wheels with lower spoke tension to give the wheel a softer ride. Today, however, George notes that riders prefer their wheels built with a higher spoke tension because most are accustomed to the ride quality of today's high tension wheels.

An interesting side note regarding the wheels for Roubaix: George recalls, the mechanics always pulled the oldest wheels first. Back in those days, the traditional wheelset was the only wheelset. The Mapei team used the oldest wheels on the truck for Roubaix and, quite simply, Roubaix would be the final ride for these wheels, prompting immediate retirement upon removal from the bike. The team's star riders would always begin Roubaix on a new set of wheels.

Here is a quick glance at the wheel builds for Johan and team:

Front Wheel
Rim: Ambrosio Nemesis 32 hole
Hub: Shimano Dura Ace 32 hole
Spokes: Sapim or DT (Aero when available*)
Tire: Vittoria
Build: 3X with lower tension in spokes

Rear Wheel
Rim: Ambrosio Nemesis 32 hole
Hub: Shimano Dura Ace 32 hole
Spokes: Sapim or DT (Aero then tied and soldered)
Tire: Vittoria
Build: 3X with lower tension in spokes

* Aero spokes were an expensive option and despite the Mapei budget, they were not always available to the mechanics.

Tire pressure remains as much art as science. According to George, the ideal tire pressure for the Roubaix course walks a very fine line, balancing enough pressure to keep the rider above the stones and low enough that the bike feels stable and provides shock absorption. Like cyclocross, tire pressure is considered too high if the rider doesn't frequently bounce off the rim.

The best riders have mastered the art of riding "lightly" enough that they can run a ridiculously low pressure without puncturing. Typical pressure for the Mapei riders hovered around 5 3/4 bars (83 PSI) for the rear and a shockingly low 5 bars (72 PSI) in the front. "The lower the pressure, the more stable the bike is over the stones," notes George.

During our talks, George laughed as he recalled Museeuw's tendency to bleed out air prior to the start of Roubaix. This served as an outlet for nervous energy and the best were always pushing the envelope, seeking the lowest possible pressure. "I used to threaten to glue the valves closed so Johan could not change the pressure," says George.

The traditional wheel set-up has been a part of Roubaix's history since the first race back in 1896. Although developments in wheel design have grown exponentially in the last few years (and some are Roubaix specific), Roubaix appears to be a race where the PROs themselves fear leaving anything to chance and the fear of embracing technology comes from a traditional mindset trusting a traditional wheelset.

The wheels featured in the photos above were built by the skilled hands of George and bound for Max Van Heeswijk's Willems Veranda's Continental Team.
