A legendary Tour de France climb to the French ski station of the same name, Alpe d’Huez is renowned for its brutal steepness and 21 switchbacks, each bearing the name of a past Tour stage winner. The Alpe became the Tour’s first mountaintop finish when the then-unpaved climb was used in 1952. Fausto Coppi won the first stage to use the 8.6-mile, 7.9%-grade climb with a time of 45 minutes and 22 seconds. Now paved, debate remains as to who holds the record for the fastest ascent of the climber’s crown jewel. Marco Pantani is generally acknowledged to be the fastest at 37’35”.

Climb categories are used in the Tour de France to rate difficulty. Climbs are ranked on a scale of 1 to 3, with Category 1 being the most severe. Riders are awarded points toward the King of the Mountains competition based on two things: their order over the top and the climb’s difficulty. The harder the climb, the more points are available. There is also a “beyond category” climb called the Hors Categorie (HC). Its extreme difficulty makes it a big factor in stage races because better climbers can pick up more points here and make up time on their rivals.

Also called a “shifter” or in England, a “mech,” a derailleur is a mechanism that literally derails the chain moving it to another cog or chainring. There are rear and front derailleurs. The rear shifts the chain across the cogs. The front moves the chain between the chainrings. You must be pedaling to shift and it’s best to use light pedal pressure when shifting.
French for “sport director,” the directeur sportif is responsible for managing almost all logistical concerns of the racing team he/she is in charge of. At the highest levels of cycling, the directeur sportif drives behind the peloton watching live race coverage on a dashboard-mounted TV and informs his team on proper race strategy via radio. He may also pass out drinks and help with medical or mechanical issues.

This is used to compare gearing. For example, on a road bike with 18 gears, there are 2 chainrings and 9 cogs. To check the gearing, count the teeth on the cogs and chainrings and create a chart with the rings on top and the cogs on the side. Then, to calculate each gear ratio, divide the chainring by the cog and multiply by 27 (rear wheel diameter). Put the numbers in the chart so you can compare and understand. The larger the number, the harder it is to pedal the gear. By comparing the numbers, it’s possible to find overlapping gears and gaps that you might want to change to improve the gear ratios.

At a ride or race, neutral support means if you have a mechanical issue there is assistance on the course available to all riders (versus in racing where team riders receive support from their own mechanics who will not help other riders).
Usually reserved for racing, a neutral zone is a section of the course where you’re not allowed to race and have to remain behind the lead vehicle(s). For example there might be a neutral zone for a few miles to allow the race vehicles and competitors to get across a strip of highway before getting onto the official racecourse. Once on the course, the lead vehicles will typically signal the field to start racing and then speed up the road.

This is a term used when installing bicycle tires (car tires too). To “seat” a tire, or “seating” tires means getting the tire beads (the edges of the tire) sitting just right on the rim. When you spin the wheel and watch the bead lines on both sides, they should sit just above the rim all around the wheel. If they dip or bulge anywhere, let the air out of the tire and try again or the tire may come off the rim while you are riding.
Also called a “seat pack,” this is a bag that attaches beneath the seat for carrying essentials.
The frame tube that the seatpost fits into.
The component that the saddle attaches to.
The twin small-diameter frame tubes that straddle the rear wheel and run from the seat tube to the rear axle.
The adhesive applied to the rim and tire to mount a sew-up tire (also called a “tubular tire”).
Also called a “tubular tire,” (because the tire is shaped like a tube), this is a type of tire that’s glued onto the rim and features a casing that’s sewn around the tube. Professional road racers favor tubulars because the tires are extremely lightweight and have a round cross-section, which improves ride quality.
Japanese manufacturer of bicycle components. Founded by Shozaburo Shimano in 1922.
A dangerous side-to-side front-end oscillation while riding caused by a damaged or in-need-of-repair bicycle, or road/trail conditions. It starts off slowly and gets worse and can easily lead to losing control and crashing. To stop a shimmy, clamp your knees against the top tube and slow down. If it happens often have your bicycle checked for problems. Also called “speed wobble.”
Proprietary technology developed by Pactimo that makes bib shorts even more comfortable in your riding position.
