Rate my spoke length calculator

spokecalc.xls to calculate the spoke length I thought that this
excellent app could use a bit of a face lift. Hence I have re-written
it as a web application that runs entirely in your browser - no
download necessary.
Try it out under: http://vocabforbreakfast.railsplayground.net/edd/
I'm keen to hear some feedback on its functionality and user
experience. Enjoy! And sorry for the shameless plug ...

Nice, myght be handy to have a page to enter measurements if the
hub/rim is not listed. But, othoh, make the buggers enter it into the
database then others can use it >:)=

There is a link on the top right hand side that says "submit
measurements" where you can do exactly that.

I like the UI - gets right down to the essentials with minimal
user input.
Took awhile for it to dawn on me that, after a successful search
on "Rohloff", I had to click the blue box under "Hubs" to reveal
details and provoke the calculation.

rim at 2x and it came out right on the money with what spoke
length is actually being used: 238 (actually, 237.5 rounded
upwards).
I'd beautify the buttons a little - make 'em look more like
buttons, capitalize the words..... but for sheer ease of use and
getting right down to it, I give the app a 10 out of 10.

Good point. I had never though of there being a situation where a
search returns only one database entry. I'll find a solution for that.

I like it! But it really needs a manual entry function. I might like
to enter my best guess for an oddball or out-of-production part, but I
don't want to subject _everyone_ to my best guess.
Likewise, there should be some way to correct data that are found to
be erroneous.
Well done; your calculator is going to be my first resort from now
on. (I don't run Excel.)
Thanks!

Nicely done. Although it perpetuates one of my pet peeves - "ERD"
I'd rather determine spoke length from a measurement of the rim
itself (ID). Find your spoke length then add length to account for
exactly how far the spokes need to extend into the nipples being used
once the nipples are seated in the rim. (easily done by measuring the
length of the nipple, holding a nipple by threading it upside-down
onto the end of a spoke, inserting the nipple into a hole in the rim
to simulate the way it would be seated, then measuring the amount of
nipple which protrudes from the inner rim surface. Subtracting that
from the nipple length gives the length of the nipple portion within
the rim.)
This is much quicker and easier to do than to describe.
ERD makes an assumption that every nipple which could be used is the
same. That simply isn't true.
If I have a rim, I can measure ID. And I can estimate ERD (ID + 10 mm
is usually close). But I can't measure ERD since that is not a
characteristic of the rim alone - it is a characteristic of the rim
PLUS the nipples being used and how far the spokes are to be threaded
into the nipples .

Vey nice. A 48-spoke option might be a useful addition for tandem
wheelbuilders, though.

I like it quite a bit, however applications like this are only as good
as the data upon which they operate. GIGO!
Example: There are two entries for "Shimano RSX FH-A410, rear", each
with slightly different dimensions. I'm guess these came directly from
Damon's database; one being 7-speed, 126mm spacing; and the other
8+-speed, 130mm. There's no way to identify which is which.
When I built a wheel on the 7-speed version of this hub I measured the
flange offsets and my hub didn't agree with either of Damon's
database's dimensions.
As someone else mentioned it would be nice to have a way to input
one's own measurements This is pretty nitpicky however. All in all a
really good effort. :-)

Wow, I missed that. Most of the wheels I build are 48 spoke, so I'd
really miss that option if it weren't there.
Chalo
Lenni
A 48 spokes option should be trivial to add and is in the pipeline.
I am also working on way for users to enter and use their own
measurements.
I'll let you know when I push the changes live.

Lenni
therefore, if you are unhappy with the measurements in the database,
you can enter your own.
Link again: http://vocabforbreakfast.railsplayground.net/edd/
Next thing on my list is to allow users to enter any decimal value for
crosses and any number of spokes.
John Everett
Your "enter your own data" feature has a way to enter the right flange
diameter twice, but no left flange entry. ;-)

Dear Lenni,
One of the nicest threads I've seen!
Getting everyone to agree that you've put together a nice calculator
and getting us all to make only the most cheerful and helpful
suggestions is amazing.
I look forward to the defaults for 72-spoke 7-cross 56-inch (top of
solid tire, not ERD) highwheeler rims, as well as 16-inch rear wheel
V-spokes (nipple-to-nipple through the hub flange).
:-)
Thanks for giving us such a handy online spoke calculator.
Cheers,
Carl Fogel

OK, for us math idiots, what does that equation mean?
Length=....?

Dear Peter,
A forearm doesn't offer quite enough room for all the details of the
first equation in "The Bicycle Wheel" appendix:

Spoke length.
You can say a lot with a red hot wire too:

I have now added the possibility to enter your own spoke counts and
crosses. You can use decimal numbers in case you have a really exotic
spoke pattern/count.

I just used it to verify spoke lengths for a 72 spoke cross-7 laced
wheel that I already acquired parts for. It returned the same length
as the spokes I got for the job. Looks like it works as intended.
The database even contained dimensions for my uncommon hub. In the
case of both the rim and the hub, I had to search by manufacturer
because it returned no results when searching the model name.
The calculator is very clean-looking and easy to use. You did an
excellent job adding valuable features without cluttering up the
form. In this regard it's a major improvement upon the DT spoke
calculator.

Carl Sundquist
Does it include Shimano HB-2200 and FH-2200 (or an equivalent)?
bjwe...@gmail.com
2200 series Shimano is typically an OEM part
and this may make information scarcer.
Some specs from the web (try google, or shimano-europe
site): http://velospec.com/components/shimano/fh2200
Typically, Shimano hubs of the same speed
and OLD have similar dimensions across
groups. For ex, various 9 speed hubs, Tiagra,
105, Ultegra, etc have the same dimensions, or
close enough, in both front and rear. So a
9 speed 2200 hub would probably be very close
to those.

Thanks. It was important to me that the user interface remains simple.
I'm glad it stayed that way.
I have added another feature today. You can display a detailed "data
sheet" of your wheel which includes the L/R spoke tension. Once you
have calculated your spoke length a "Complete data" link appears.
This feature was suggested by the man himself - Damon Rinard.
Carl Sundquist
Thanks Ben.
Low(er) quality or not, the 2200 series hubs are a bargain. I see them
as low as $13/$23 for the front and rear respectively, on the net.
Quiet, too.
Velocolour
I used the calculator to build up a wheel yesterday it worked great.
The calculations were about 2mm shorter on either side than what I
calculated using the old Sutherlands book. Bang on.
Thanks,
