how do they steer bobsled
They steer a bobsled with a simple rope-and-ring system that turns the front runners, plus subtle body lean and weight shifts to fine‑tune the line down the ice.
The Basic Steering System
- Modern bobsleds have two metal rings (often called D‑rings) in front of the pilot.
- Each ring is attached to ropes and a pulley mechanism that turns the front runners (the front blades).
- Pull left ring → runners point slightly left, pull right ring → runners point slightly right.
Because they’re going 80–95 mph, the pilot uses very tiny pulls; big, jerky moves can make the sled skid or even flip.
What the Pilot Actually Does
- The pilot sits in front, knees up, hands on the rings, reading the curves from memory and from feel.
- They “paint” the line with micro‑steers, often pulling a ring just a few millimeters, then letting the bungee system pull the runners back to center.
- Every bit of steering input usually needs to be “given back” (a small counter‑steer) so the sled doesn’t keep drifting and hit the wall or climb too high in the curve.
An example drivers use: if the back of the sled starts sliding out to the right, they’ll give a couple of quick, light pulls on the right rope to let the rear “catch up” and straighten.
Role of Body Weight and the Crew
- Besides the ropes, the crew also helps steer by shifting weight very slightly in turns.
- A subtle hip or shoulder shift changes how much pressure each runner has on the ice, nudging the sled toward one side of the curve.
- Push athletes tuck down to stay aerodynamic but still “breathe” with the track: tiny bobbing motions to support the line without destabilizing the sled.
The classic “bob” in bobsled comes from this rhythmic weight shift during early versions of the sport.
Braking vs Steering (Who Does What)
- The pilot: steers with the rings and calls the rhythm of the run.
- The brakeman: sits at the back and does not steer; after the finish line they pull a lever that drops metal teeth into the ice to slow and stop the sled.
On TV it looks like everyone is just tucked and riding, but one person is constantly steering with fingertips while everyone else is acting as movable ballast.
Why the Steering Has to Be So Gentle
- Turning the runners more sideways increases friction and scrubs speed, so the fastest pilots steer as little as they can while still holding the ideal line.
- Tracks are banked like high‑speed roller‑coaster turns; if you steer too hard, you can climb too high, skid, or flip out of the corner.
- Races are often decided by hundredths of a second, so a couple of sloppy steers in one curve can lose the whole event.
In practice, a “good” run can feel surprisingly smooth and quiet to the pilot—because all the steering is tiny, early, and precise.
TL;DR: They steer mainly with small pulls on rope‑connected rings that twist the front runners, then let elastic cords re‑center them, while using slight body‑weight shifts for extra control—all done as gently and precisely as possible at highway speeds.
