Why are junior gears restricted?

Why are junior gears restricted?

In a nutshell, Junior gear restrictions were made: 1. to help juniors learn to ride tactically; 2. to keeping early bloomers (strong kids) in the pack; 3. to reduce tension in developing joints by having them learn to spin more instead of cranking so hard.

What size chainring is allowed for junior gearing?

There is no junior gear restriction for cyclocross or mountain bike racing. Maximum road junior gear rollout for ages 6-18 is 26 feet (7.93 meters), which is closely approximated by a 52×14 (52-tooth chainring, 14-tooth smallest cog) and a 700 X 23C rear tire.

What is the junior gear restriction for road racing?

26 feet
The test to see if a race bike is legal or not is called the “rollout method” or simply “junior rollout,” which is the distance a bike travels backward in a straight line through one full pedal revolution when the bicycle is in its largest gear. The junior gear restriction for road events is 26 feet (7.93 meters).

How do you restrict gears?

First change your gears so that the chain is sat on the sprocket you want to set as the limit. Then, without pedaling, click the gear lever back to the current set high gear to release the tension on the cable, the chain will now be out of alignment (picture 1).

What do you need to know about junior gearing?

Junior gearing restrictions are part of USA Cycling requirements for juniors (through age 18) in cycling competition. The rules do NOT cover actual ratios or gear teeth. Instead, they test something called roll-out . Simply defined, roll-out is the distance a bike travels in one full pedal revolution when in its highest gear.

How big does a mountain bike junior gear have to be?

There is no junior gear restriction for cyclocross or mountain bike racing. Maximum road junior gear rollout for ages 6-18 is 26 feet (7.93 meters), which is closely approximated by a 52×14 (52-tooth chainring, 14-tooth smallest cog) and a 700 X 23C rear tire.

Junior gearing restrictions are part of USA Cycling requirements for juniors (through age 18) in cycling competition. The rules do NOT cover actual ratios or gear teeth. Instead, they test something called roll-out.

Why are there gear restrictions in British Cycling?

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. • It encourages young riders to race using tactics as opposed to using bigger gears to go faster.
