Mavic Recall

Announcing a product recall is not typically the type of info we share here at BKW, but Mavic's recall of the R-SYS front wheel is worth mentioning.

Friction Freedom Chamois Cream

The fall is my favorite time to try out new products. When my mileage and intensity are down it is a good deal easier to incorporate a new variable into my routines. This fall we were introduced to a number of new chamois creams.

Radio Freddy and I came up old-school, applying Noxema to the undercarriage to ward off saddle sores and miscreant chafing. Back then my issues were always chafing and saddle sores in an around my perineum. Somewhere along the line, pads improved and my trusty Noxema fell out of use.

And then I began using a wardrobe's-worth of team shorts that were poorly cut. As a result, I experienced chafing in some new places and on some pretty sensitive instruments.

Now chamois cream users fall into one of two camps. Either you put it on the pad, or you put it on your skin. I prefer to lather up my personal contact points as it were. I briefly went back to the old standard bearer of Bag Balm, for the simple reason that while I liked the cool feel of Noxema, I had never put applied it to the reproductive apparatus. The menthol effect felt not just alien, but a bit wrong. After being reminded that the active ingredients that produce the Vap-O-Rub feeling are natural antibacterial agents, I knew what I needed to do: Get over it.

The upside to the minty zing is that I know instantly if I missed a spot. The feeling does make for a lively start to the morning.

Since getting comfortable with the magical menthol experience, I've tried a number of new chamois creams. And while I never thought I'd get excited about a new chamois cream the way I can for a new embrocation, Friction Freedom changed my outlook.

I've noticed that a few of the chamois creams out there get absorbed fairly quickly and that my skin ends up feeling like I put a hand lotion on it a few minutes ago. Not so with Friction Freedom. I was three hours into my first ride with the stuff when I made a bathroom stop. I had some trouble with my grip.

Friction Freedom is paraben-free, and while I don't know much about parabens, I'd like anything that's going to be on my skin for longer than it takes to watch a Francis Ford Coppola movie to be controversy-free. These preservatives are cause for concern for estrogenic activity and as carcinogens, so leaving them on your skin all day might not be the healthiest option.

Getting to the end of a 5-hour ride with a surface slicker than a politician's pitch is just my idea of comfort. I kinda wonder if this stuff might not have a second life in a, uh, more amorous application.

Check out Friction Freedom.

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.

Bring the Noyes - 1993 World Championships

Interbike is great way to see the latest and greatest, and any films from the gang at World Cycling Productions provides insight into the PRO peloton and the art of racing in the big leagues. Both, however, lack the depth and insight into what it means to be deep in the PRO world. Deep in the sense that you are living and breathing PRO cycling.

BKW recently caught up with veteran of the PRO ranks: journeyman, mechanic, and Belgian resident George Noyes, to discuss the subtleties that make the PRO circuit so enthralling.

About Mr. Noyes
George began his career in the mid-eighties as a team mechanic for the Schwinn PRO team, graduating to the International stage, and making his Tour/Classics debut with the 7-11 team. From there, George built on his experience and knowledge as head mechanic for the Motorola squad in the early 90s, a short stint at Cofidis, and then the mother of all Classics squads, Mapei. George’s professional experience included Andy Hampsten’s Giro win, Armstrong’s World’s victory, and complete and utter Mapei domination at the “Queen of the Classics,” Paris-Roubaix.

George has prepared machines for some of the 20th century’s greatest riders and lived the "behind the scenes" experience by which BKW is so captivated. Over a few espressos, George opened up about his experiences and, naturally, I probed him for information and a sense of what his life was like while working for these teams. Honestly, there was so much incredible information that came from our discussion that it would be impossible to compile it into a readable form in a single post. Therefore, based on the size of George's experience, I'll provide small vignettes that comprise George’s experiences. Some parts of our discussion dealt with the classics, others with the Grand Tours. A few times, we merely spoke in generalities, other times, in full swing with detailed accounts of the weeks, days, and hours leading up to the moments in PRO cycling that are burned into all of our memories. The title for these posts will be “Bring the Noyes” and, it's only fitting that I commence this series with a tale of LA’s World’s victory in a rain-soaked Oslo in 1993.

Oslo, Norway - August 29, 1993
Lance has always been a leader. Early in his career, LA's tough exterior and strategic mind were beginning to take shape, a glimpse of the road ahead perhaps. In the days leading up to the road race, Motorola's team management had exhaustively discussed race day tactics and without question, LA felt he had the legs to capture the rainbow jersey.

Motorola's staff and riders awoke to a steady rain the morning of August 29th. LA was to ride a Tennessee-built titanium bike for the day's event. George had prepared Lance's wheels and glued a fresh set of tubulars. The pressure for the day's rain: 7.5 bars (r) and 6.5 bars (f). As the mechanics feverishly prepared the team's machines, LA and Motorola DS Jim Ochowicz had come out to the service course to check on the bikes and the weather. Ochowicz was especially concerned about the weather, the rain, and the team's chances. The big issue for the mechanics focused on LA's bottle cages. Apparently, the threaded inserts that held the bottle cage into the frame would not tighten properly and both cages were rattling. There was risk they would fire off mortar-style, mid-race. With the start approaching rapidly, one of the mechanics disappeared into the hotel to seek out a solution. He returned a bit later with four, self-tapping screws; the kind an old ski binding would use to mount to a ski. (In fact, they were the very hardware that held the hotel owner's bindings to his skis!) The four simple screws were forced into the frame, securing the bottle cages to the frame. (Rumor has it the hotel owner had no idea that the screws from his skis had been carried to a World's victory. That is, until his ski holiday was brought to an abrupt close mid-run. Apparently the screws never made it back to his skis.)

As George applied the finishing touches to LA's machine, Ochowicz and LA continued to discuss the weather and the team's chances and George was treated to a front row seat, which made him privy to a defining moment in LA's career. In fact, in hindsight the comment seems so telling: As Ochowicz expressed his concerns for the weather, LA with an air of coolness and simplicity, reassured Ochowicz by saying, "Let me handle it." In 1993, LA knew he had the mind to be a legend, it was only a matter of time before he began to lay the groundwork. Hours to be exact.

The Urge

Suppose for a second that you are God. Not Eddy Merckx, but God. It’s T-minus 1 hour to the Big Bang. What would you want to have happen? You’ve got the power to create anything, everything. Wouldn’t you want explore the range of your own ideas?

Even though organized religion doesn’t often discuss what God wanted to occur independent of our arrival, I have often looked at our world and beyond and attempted to tease meaning from what I see. The conclusion I draw is that our maker wanted diversity, wanted weird, wanted beauty, wanted destruction, variation, surprises, confusion and the unknowable.

While I struggle with the idea that God actually likes war and death, I think they must have been an intended expression in the range of creation and no less important than waterfalls, hummingbirds and fluffy kittens.

One of my favorite features of the cycling world is, similarly, the incredible range of ideas and creativity we see. Bicycle frames have been made from steel, aluminum, titanium, carbon fiber and more (anyone remember beryllium?) Marino Lajaretta gave us knickers. We’ve got bicycles made specially for time trials, for road races, for dropping off cliffs and going to the store. Think about how Miguel Indurain wore a cycling cap. Bright minds have invented devices to track our heart rate, record the wattage we generate and even map the routes we ride in real time. What about the ever-interesting and changing route of the Tour de France? Let’s not forget that the bicycle has evolved from a single-geared contraption to a sophisticated drivetrain that can contain 30 gears or be shifted—gasp—electronically.

I write this as a way to frame my incomprehension at the blowback against technology that I sometimes see. I saw it against heart rate monitors and cyclocomputers. I saw it against integrated brake and shift levers. There’s opposition to carbon fiber frames and you’ve seen it against electronic shifting. On the other side, there are those for whom the world can’t evolve too quickly. They’d sooner drive a stake through a lug than ride steel or overshift a downtube lever.

Personally, I’m grateful that a lug cut by Peter Weigle doesn’t look like one cut by Brian Baylis or Richard Sachs. There’s nothing better than when an attack comes in a surprising way or at a surprising location. I love that Campagnolo, Shimano and SRAM are engaged in a battle royal of fresh ideas. Love it. As much as I love the age-old courses of the Spring Classics, I’m always excited to see a fresh course used at the World Championships. And every time a frame manufacturer comes up with a fresh idea, a new way to express the road bike in carbon fiber, I’m game, especially if they’ll give me some insight into how it was designed and manufactured.

Someday I’m going to have a durable 12-pound bicycle with eletronic shifting automatic transmission smooth. It will track my course, HR, wattage and provide POV video of my ride in a 1-ounce device I won’t have to plug into a USB port. It will be unspeakably stiff in torsion and offer 5mm of vertical compliance. It will have the aerodynamics of today’s best TT bikes. It will be gorgeous. It will fit me perfectly.

I’m grateful for the creative urge that drives the sport's engineers, racers, builders and designers to make my pipe dreams reality.

Ridden: Dura-Ace Di2

We’ve just returned from our first opportunity to ride Shimano’s leap into the great unknown. Unknown because no one really knows how the market will accept it. In a down market fewer $5000+ bikes are leaving shops and there remains some resistance to bikes that can cost upwards of $10,000 even among those who aren’t hurting.

Already there is blowback to a group that will price more expensively than many well-equipped bicycles. The tech geeks are salivating and the traditionalists are wondering what unasked question has been answered.

I’m going to split the difference on this one: We don’t need Di2 the way we need more efficient cars. The Segway was an invention that hasn’t made the world more interesting. On the other hand, I wouldn’t want to still be stuck on Nuovo Record. Great as it is, I’m glad for integrated brake and shift levers—now there’s an answer to a question someone asked.

A few thousand people have already had a chance to ride Di2 on a trainer. I was excited to try it out on the road and feel what it was like under braking and attempting to downshift in corners and upshift the chainring during hard out-of-the-saddle efforts.

I’m going to cut to the chase: Di2 rocks. The shifting is simply the fastest I’ve ever experienced, faster, I dare say, than I would have imagined possible. While rear derailleur upshifts aren’t much faster than current Dura-Ace, the front derailleur upshifts are honestly smoother and faster than I thought possible, even when out-of-the-saddle and stomping the pedals in a Tom Boonen-goes-bye-bye effort. As a matter of fact, the faster your cadence, the faster the shift.

The automatic front derailleur trim function is another neat touch. Even if electronic shifting is an answer to an unasked question, a front derailleur that needs no trimming is something we have all fantasized about at some point.

I found the sound of the shifter, when far from the halls of the Sands Convention Center (and the crowds milling around the bike), to be strangely amusing. It’s not terribly unlike the sound of some brake pads on a carbon fiber rim, the difference being that the sound doesn’t last long (very short for the rear derailleur and just twice as long for front derailleur upshifts) or change in pitch.

The textured lever hoods feel like a rubber diamond file pattern. I’m not sure I’d want to ride on these for more than an hour or two with no gloves. That said, grip won’t ever be a problem on these.


Short of coming up with a lifetime battery, the engineers at Shimano have thought of most everything it would seem. I am precisely the guy who would forget to charge his bike and find himself riding home in the 50x17 at the end of 85 hilly miles, but I can’t escape the intrigue of this stuff. Heck, in the event of a crash or anything else that might throw off shifting performance, the electronic equivalent of the rear derailleur barrel adjuster is located near the handlebar so that adjustments can be made on the fly.

One thing I barely had time to experiment with was middle finger braking from the drops while downshifting with my index finger, or braking from the hoods and sliding my middle finger around to the downshift button. I’ve always appreciated how you could brake and downshift the rear at the same time with Dura-Ace, and I don’t particularly want to give that up.

There’s no doubt in my mind that this stuff is cool enough to warrant its place in the market. Whether it gains acceptance due to the serious coin it will take to purchase the stuff isn’t my say; units sold will be the judge.
