Junior gears

Peter Gierga

2003-08-16



I'm Bringing my 10 year old friend Brandon to do the TT. Are there gear

restrictions? If so. If I take off the big ring and and leave the 39x12 will

that pass? Can I block out the shifting or do I need to remove the chain

ring. (its my wifes bike)

                                   Best, Peter

Who is Charile Brown? Don't you mean Charlie Brown? Oh, and on a sidenote,

the "Big Gears for Small Juniors Council" is in full support of a Barney vs.

Silver Helmeted PowerRanger sprint match.

I want to see a rematch.



I will put 200 francs on Auker to take Burney in the sprint. No gear limit.

Robert, with all due respect, when I out-sprinted you to win the

District Road Race in 1980 (I think that was the year :-), it was with a

53x12, and it worked real fine...

(Seriously, there are appropriate gears for different situations...in an

extended tail wind section, if you've got 10-20 inches of gear less than

the rest of the field, your forced spin's gonna not going to be

optimal! On the other hand, a twisty criterium requires snap and

acceleration, and that ain't gonna happen at 50 rpm!)

It seems to me there are 2 very different view points on this matter:



1. Juniors with aspirations outside of Oregon need to get used to the gears

they will be REQUIRED to use in national and international races.



2. Local juniors who do not plan to go any further than Oregon want to use

any gear they want.



For those who fall under group #1, just do it and get on with your life.

These gear restrictions are from the International governing body, and if

they lift the rule, so can we. Buy one set of gears and use them in all the

races. One junior from many years past (Hans Selvog) won Delta Park against

the Sr. men in a 48x15.

When I raced as a junior MANY years ago, we used the restricted gears for

all our races, even with the seniors. I can honestly say that none of us

ever lost because our gears were too small. We lost because we crashed, did

not know enough to get in the correct position, or used too much energy too

early in the race. We were juniors and learning.



Greg Lemond used those restricted gears as well when he raced and won the

Junior road trials. By the way, he was too young to compete against the

'older' juniors at the international level and needed to wait one more year

to win the worlds as a junior. He also used restricted gears when he raced

against, and beat, most of the senior riders in the USA.



juniors who fall into group 2 should talk to an experienced coach about the

use of a fixed gear bike in the winter, and riding the track in a small gear

to develop the spin necessary to be really competitive. If a junior

develops the proper spin, s/he can beat another junior in a larger gear in

anything except (perhaps) a downhill sprint.



For example, a rider in a 50x15 (50 tooth ring and 15 tooth cog), pedaling

at 90 rpm is riding at 24.1 miles per hour. To ride at 32 miles per hour,

the rpm's increase to 119. How often do you ride a race at 32 mph for a

long time. Delta Park usually goes at an average of 28 miles per hour. If

you use 52x14, 90 RPM gives you 26.8 mph. 110 RPM in the same gear is 32.7

mph.

As a Senior rider, I won Delta Park many times. I never used a gear greater

than 53x14 in the sprint, and usually rode the tailwind section in 53x15,

and the headwind in 53x16 or 17. It can be done, and done well.

Once again, junior gearing is a royal pain:



            http://www.geocities.com/beallcycle/gear/index.html



1.. You can't simply pick a set of gears and assume that ratio will =

work with your bike; rims and tires may put a combination acceptable on =

one bike over the restriction for another bike.

2.. The modifications are expensive. You do have to buy chain rings or =

cog sets and spacers, etc.

3.. As a retired orthop=E6dic surgeon I can say that there is no =

evidence that big gears hurt growing children. I wrote a letter to the =

USCF several years ago suggesting the abandonment of gear restrictions =

and heavily footnoted this statement with references to the orthop=E6dic =

literature. Unfortunately, I don't have a copy of that letter on my =

machine.

4.. The rollout before the race is a courtesy, the rollout after the =

race determines if your kid complied with the restriction. If you take a =

wheel from the pit or from support and that wheel puts you over, you DQ. =

And there is every imaginable combination of ways parents try to meet =

the restriction.

I am out of this; Rusty and Allison are safe as a senior and U-23. This =

is from a dad who at one point had a boy and a girl racing at the same =

time:=20



    a.. Senior unrestricted

    b.. Male USCF restricted, blocked gears (long screw) for local races

    c.. Male USCF restricted, mechanical block for nationals

    d.. Male UCI mechanical block for Olympic Festival [UCI and USCF =

restrictions were different]

    e.. Female USCF restricted, blocked gears (long screw) for local =

races

    f.. Female USCF restricted, mechanical block for nationals

    g.. Female UCI mechanical block for Olympic Festival [UCI and USCF =

This also from a dad who DQ'ed his own son at the 1994 junior national =

road race in Snoqualmie by putting on the wrong wheel.
