Descending Techniques
By spokesman | May 29, 2009
Watching this year’s Giro D’Italia provided a great way for cyclists to learn about descending skills. The race route included many technical descents with narrow roads and tight hairpin curves. The cyclists had the advantage that the roads were closed to traffic so that they could use the entire road without having to worry about cars. Never the less, I am amazed at how fast these racers go on unfamiliar roads. Here are some of the techniques that you can observe in a professional race.
Choosing The Optimal Line - The cyclists choose their line in advance of the curve. They enter it from the outside edge of the road in order to get the widest possible angle. As they go through the curve, the cyclists cross the apex (or the midpoint of the curve) at the opposite side of the road on the inside edge of the curve. They exit the curve, on the outside edge of the road. This path can be seen in the picture above.
Braking - The professional cyclists don’t appear to use their brakes very much, however most amateurs would need to brake on such steep descents. You should only brake before entering a curve. Braking during the curve will reduce the traction for cornering. If you need to brake in the curve it is best to straighten your line. On long descents, it is best to pump the brakes to avoid heating the rims and getting a blowout. You can slow down as you descend by sitting upright and getting out of an aerodynamic position.
Leaning - The cyclists lean their bikes into the corner and try to keep their body upright. This makes it easier to transition into and out of corners. They lift the inside knee to avoid scraping their pedal on the ground as they lean. They also use the position of their inside knee to shift their weight and steer the bike.

Good article. Many pros can gain an advantage on descents.
When leaning into a curve, I’ve found that putting pressure on the “outside” foot gives more control when that leg is straightened. Gotta remember, though, the pros have the advantage of closed roads!

Yes, a well written article. Gene had a good point as well about putting most of your weight on the outside pedal, with your leg straightened, as it gives your tires a much better grip on the road surface. Also, scan ahead for sand or loose gravel that’s washed out onto the road, and straighten out your line if you have to ride through it.
