At Penrith no one cares in the open racing, and the CA website says
Please note that all competitors are required to satisfy a roll out for all junior events.
Apparently the rationale for this rule is to
The main purpose of the junior gear restriction is to help the young rider develop a good pedal cadence and to avoid injury.
a few points i have noted out of my ignorance !
1. fair enough in junior races, but it seems stupid to fork out $15 race entry to be told that i have to have half the gearing of everyone else in the field.
2. how does restricted gearing promote good cadence?
there are some elite juniors that i race in c grade 'with' around the place. they stay with the bunch with a ridiculously high cadence for the whole race - that cant be good for them also they get in the way the minute the pace goes up as they cant compete in any sprint.
whats the go in most places. i'm not overly keen to have the kids race open with overly restricted gearing
