AI quick summary
- Half-wheel overlap is the #1 cause of group crashes — never let your front wheel overlap the rear wheel of the rider ahead. Ride smooth, predictable lines
- Call and point out hazards: 'hole!', 'gravel!', 'car back!', 'car up!'. The riders behind can't see the road — your calls are their eyes
- Paceline rotation: the front rider pulls, then peels off (to the left in a right-side traffic country) and soft-pedals to the back. Keep pulls short (1–5 minutes) for a faster group; longer for a social ride
- Don't surge when you get to the front — the most common mistake. Maintain the same speed the previous rider held. Surging drops the riders behind and shatters the group

The basics of safe group riding
The golden rule: ride smooth and predictable. Sudden braking, swerving, or surging are what cause crashes in a group — the riders behind you can't react in time. Every move should be gradual and telegraphed. If you need to slow, do it gently and call it out ('slowing!'). If you need to stand (out of the saddle), do it smoothly without kicking the bike back (which can touch the wheel behind).
Never half-wheel. Your front wheel must not overlap the rear wheel of the rider ahead — if they swerve or slow, you go down, and you'll take out the riders behind you. Ride directly behind the rider ahead, with a small gap (10–30 cm in a tight paceline, more in a social group).

Calls and hand signals
The standard calls and signals. Pass them back — the rider behind you needs to hear them too.
| Call / Signal | Meaning | Action |
|---|---|---|
| 'Hole!' + point down | Pothole ahead | Avoid it; signal the line |
| 'Gravel!' + point | Lose surface | Don't brake or swerve; hold line |
| 'Car back!' | Car approaching from behind | Single up; move right (in right-side traffic) |
| 'Car up!' | Oncoming car on a narrow road | Hold line; don't pass |
| 'Slowing!' / hand out, palm down | Group slowing | Feather brakes gently |
| 'Stopping!' / hand up, palm back | Group stopping | Brake smoothly, don't swerve |
| 'Clear!' (at a junction) | Road is clear to proceed | Pass the call back; don't assume it's clear for the riders behind |

Paceline rotation
In a rotating paceline, the front rider does the work (breaks the wind), then peels off and drifts to the back, letting the next rider take the front. The rotation keeps the pace high while sharing the effort. In a right-side traffic country, the front rider pulls, then moves LEFT and soft-pedals back; in a left-side country, reverse.
Keep pulls short. In a fast group (race pace), pulls of 1–3 minutes keep the speed high. In a social ride, pulls of 5–10 minutes are fine. The mistake: staying on the front too long, getting tired, and then slowing the group down. When you start to feel the effort, pull off.
Don't surge. The most common paceline mistake is accelerating when you reach the front — the previous rider was holding a steady pace, and surging drops the riders behind. Match the speed. Your job at the front is to maintain the pace, not to attack.

Echelons and crosswinds
In a crosswind, the group forms an echelon — a diagonal line angled away from the wind, so each rider is sheltered by the one upwind of them. The rotation shifts: riders peel off on the leeward (downwind) side. Echelons are advanced and require practice; they also take up the full width of the road, which is why they're legal in races but antisocial on public roads with traffic.
If you're dropped from a group in a crosswind, the echelon is why — there's less shelter the further back you are. Fight to stay near the front in a crosswind; the back is where you get shelled.
