Crankarm Length for Taller Rider

Joe

Just curious--I'm a rider about 6'3" tall (with a 36"
inseam) and am trying to figure out ideal crankarm length.

For other riders out there with (approximately) my inseam
and/or height--what size crankarms do you use?

Most people will tell you 175mm cranks are long enough but
most people are shorter than you too.

I'm 6'2"; I'd buy a 180 crank set if I could afford it, but
I ride 175 now. In my experience, anything longer than 175
is priced at an absurd premium...if it's even available.

One of the guys at a nearby lbs is 6'5"; he has a 185
crank set on his bike. He paid more for those cranks than
I typically spend on a whole (used) bike. (Yes, I'm
*that* cheap.)

Frankly, though, having ridden his and mine both, I can't
say that I think that the extra length is all that valuable.
Your preferences may vary. Remember that the distance from
the ground to the BB on a frame built to your scale may not
be any greater than on one for a medium-build rider, so the
longer cranks may result in reduced pedal-to-ground
clearance. This can be a concern for some riders and
conditions.

175 Road? 175 MTB? 175 Track?

I'm not (6'10"), and I use 175 mm cranks exclusively. I've
heard that "proportional" cranks would make me much faster,
but even if I had the $$$ for 200 mm cranks, and the frame
that would take them, I'd still have to somehow solve the
problem of my knees smashing my ribs -- plus, I'd be too
fast to ride with my friends anymore.

I'm 6'8", with about a 40" standing inseam. I have bikes
with 170mm, 180mm, 185mm, 190mm, 196mm, and 205mm cranks. I
enjoy all my bikes, but all else equal I like my longest
cranks best. It doesn't keep me from riding, and enjoying,
my bikes that are equipped with shorter cranks.

I feel like I can ride faster with less effort when I use my
long cranks, and my longest, fastest rides were all on 196mm
Bullseye cranks (which I have had for many years now).

It would be easy and inexpensive for you to try 180mm
cranks, so why not?

I've got 20cm cranks on my Cannondale CAAD2 touring, and
I'm tiny at only 193cm with 94cm inseam. My son recently
switched to 21cm cranks (he has a 102cm inseam) and says
that cycling now feels more like running. I take that to
mean that pedalling now feels a more natural movement -
and I agree.

I think someone your size ought to try longer cranks. 180s
are readily available, and I'm sure you could borrow some!
If you find you get along with 180s, then you might think
about getting some 210s!

Interesting, I have the same frame (CAAD2), but in a touring
model. My BB is low as it is, I'd really worry about using
longer cranks.

I haven't noticed a difference going between 170 and 175, so
I'm not sure I'd notice the change to 180. I'd probably buy
180 if they were not usually a special order. I'd love to
experiment with 200-210's, just to see what they feel like,
but that's a very expensive experiment.

Have you got a source for a 180 or 185 crank set that's
under $75? Nobody in this area will part with one for less
than twice that.

Interesting contrast- in the recumbent world 155mm cranks are the latest rave with active discussions and experiments with 140, 125, and 100s picking up steam.

Here's a 180mm crank for $90 including the bottom bracket:

bin/hazel.cgi?action=DETAIL&item=451050

Here's a 185mm one for $80 with an American BB, but a
threaded BB is available for it:

http://www.danscomp.com/cgi-
bin/hazel.cgi?action=DETAIL&item=451057

I don't know much about the first crank I listed, but the
Primo crank in the second link is an exemplary piece of work--
cold forged 7075 aluminum arms, heat treated 4140 CrMo
spindle, precision cartridge bearings. In both materials and
mechanical integrity, it totally outclasses any crank Brand
S ever sold.

For a step up in price, but still under $150, there
are cranks offered in 190mm, like Redline Flite and
Profile 3-piece.

Bullseye and Profile will make up to 222mm cranks on a
special order basis.
