Gear Restrictions for Youth and Junior riders



If your youngster is racing in British Cycling (BC) road/track/roller racing competitions they are governed by BC rules – this includes gear restrictions to the bicycle which can mean your gears need adjustment to 'lock-off' the highest gears.

(see further down for British Schools Cycling Association (BSCA) gear restrictions)

BC Guidance on the need for gear restrictions:
• It ensures all riders compete together on a fair and equal standing
• It helps to reduce the risk of overuse injuries and avoid strength imbalances in young riders; it may also help riders to develop good pedalling technique
• It encourages young riders to race using tactics as opposed to using bigger gears to go faster. This will help to support the riders in learning new techniques which they will need throughout their competitive career


Before a race the Commissaire will perform a roll out test with your bike in its highest gear, only if it passes this test will you be allowed to race. Don’t change your gears after testing as they will test a few riders again after the finish.
