But the usual is 50x15. Regarding 15 - 16 y/o kids 50x16 is the maximum... that is 6.60 meters per pedaling.
48x16 is like 50x17 or so... thats like 13/14 year old kids.
Here in the U.S. Juniors are age 10-18 with four age groups, each with it's own gear limit. On the track, age 10-12 the limit is 6.00 meters rollout (48x17), 13-14 is 6.36 meters rollout (48x16), 15-16 is 6.78 meters rollout (48x15) and the 17-18 age group is unlimited. For the road all age groups are limited to 100 inches.
