Thanks for all the problematisation around crank length. I've never thought
much about myself as I've, like most people, rode what was available. I
started looking around and it appears that there's a bit of research (that
reiterates much of what's been said so far). My discipline isn't

I’m curious how those who ride very upright, with say a 58 cm Bosco 6”
above saddle, deal with riding straight into strong winds if you live in
windy areas; say 22 gusts to 28 which is pretty common here in Spring. Or
for that matter how you pedal up hills. I can’t do either without bending

Probably a combination of several things create individuals' perception of
optimal crank length. I'm not going to say anyone should do this or that
based on my spec or choices. Pro cyclists are so narrow of a group that
other industries would select as the model for equipment selection. They

I wonder if there is any correlation between the crank length that works
best for people and the cadence they prefer to ride? I have a suspicion
that some people with longer legs who favor a slower cadence might do
better with long cranks. So much of the talk about crank length centers on

The segue to crank length and pros and cons is an interesting tangent. I
have no dog in the debate about the aero question, but I do recall
switching from 170s to 175s when I tried riding fixed offroad with a 60”
gear. Uphills were fine; the problem was downhills and flats without strong
headwinds:

I suspect many people would like the feel of short cranks regardless of the

are often not even noticed. Aerodymamics comes into play from short cranks

According to some, all you need to unlock your dominance is buy shorter
cranks.

Bill,

I've waited many years to reach my dominant age which I thought would be
58. Now that I'm almost there, you tell me that I missed it! Haha.

Whoa now…replacing all my long 170 cranks and wide 420 bars is bound to put
an ugly dent in the bank account. For sure…considering the tidy collection
of beautiful silver bits I’ve accumulated to replace stuff that will
inevitably (if I’m lucky) need replacement.

Haha. There is a generational talent in professional road racing, and that
individual is dominant at age 22. That individual continues to improve
through age 25, and incidentally switches from 172.5mm to 165mm cranks.
He's just entering his prime, but now, all over the place, we're hearing:
I switched from 180 to 165 crank arms on my touring bike because of a very
low bottom bracket.A bit embarassed to say I can’t feel a difference, and
don’t feel like I a fiding any faster, though thats rarely a goal.

You'd better try it and see:-) Though Riv, rather strangely, only seem to
offer their own brand cranks in long lengths...

You know the gusts are strong when you have to stand on the flats! But
