London Fixed-gear and Single-speed

Having build my first wheel recently and used Damon Rindard's spokecalc 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 in your browser.

Try it out under: http://lenni.info/edd/

I'm keen to hear some feedback on its functionality and user experience. Enjoy!

nothing happens when I hit enter.

I am running firefucks

ok, simplified search parameters now I'm getting something.

Nice!

Love the simplicity. It's really effective but might need somewhere where you can type in the measurements (with explanation of how to do measurements) just incase you can't find your hub or rim.

Works mobile with opera mini.

Oh great! I hadn't thought about that. .

Nice, it would be great if you could take submissions of new/different parts? Creating an official Spocalc master version or something...

i think a pull-down of different makes available would be better than having to guess names, also i couldnt get Hope Pro 2's....? or mavic 717's....? or any actual results on the calculator? maybe its me. i think if you picked all your right parts then hit a 'go' button, that would be better.

Does not work for me :(

no H Plus Son...
sad face :(

Good stuff !

Can you put 650c rims in there too ?

Groovy.

This will really help the person I get to build my next wheelset ;)

Maybe I'll implement search suggestion a la Google Suggest.

Are you using Internet Explorer? I could not get it running there either. Working on it. IE is an absolute pain in the ass!
I have added all the hubs and rims from spokecalc.xls plus everything from Arup's website. If it wasn't in there, it won't be in my database. I'll add functionality that lets users submit measurements. 650 rims aren't fundamentally different, aren't they? Therefore shouldn't be a problem, right?

Thanks for the comments guys!

Don't design it for IE. People who use IE shouldn't be riding fixed anyway.. it's far too dangerous for their precious little selves.

I couldn't agree more. However, to tell 60 % of the internet to go fuck themselves is a little rude.

why? i think a more appropriate number would be 95%

Nice work. My request is for less that 32 spokes as well please.

That'll be really easy. What are common spokes below 32?

I'm more than a little rude. Put "designed for firefox you IE-using cocks" with a link to download Firefox on the default page :)

You always forget 18.7 Prav, come on!

what rims come in 18?
at least 16 is every other hole on a 32...
22?

I have added this. You may need to hit Shift+Reload in order to clear the cached version from your browser.

Ksyrium ES have 18.7 spokes. Get with it!

Actually, I had a look at the original excel file and the following 650s are in the database.

Excellent work. Like it. I have the ERD for H Plus Son which I measured last week during a build - 557mm. I'll keep adding more hub specs to my site as and when I get them. Feel free to take it. But if you implement a way to enter data on your site then I could pop it in there too. You'll need lots of validation checks so that erroneous data doesn't get in there such as flange diameters of 200mm or whatever.

thanks for the addition. I need people like you at work.

Me "Can you add this"
Them "Why can't you do it yourself?"

sigh

I have three 18 spoke wheels, 2 x mavic and a Zipp 400 (the Zipp 400 58mm deep carbon tubular at the bottom of ehren_fried_chicken's 650c list above)

it's not that hard to put sugar in your own coffee you know Ant...

Cheers !

even with my hungover head...this is just about manageable to use...nice one.

Who do I sue if I use this spoke length calculator and it turns out to be wrong?

Switched to ffox - computer says no...

jQuery - nice, like the way you have put that together

Only thing I don't really like is all the Red that flashes around when you've selected a search result. Using red signifies that there has been an error, rather than something successfully happened.

otherwise, nice one.

True but why else would I give them a job?

You will be pleased to know that I offer a full refund of the usage fees you paid for using my calculator.
Good point. Hadn't thought about that and will change it.

EDIT: Changed the colours to dark blue and light blue. Again, hit Shift+Reload to get your browser to refresh everything.

Ahhhh you have to hit enter to search....user fail

Should be a button called "SEARCH". Much more user friendly.
It should swear at you when you click it too.

I have added a search button. Now Ved can use it, too.

Good work - so simple compared to spocalc!

Cool. My consultancy fee is being prepared for binding and will be couriered over before close of play today.

You might loose a few people (those living below the gamma line) with black on dark blue for your spokes and crosses selected boxes.

Squint or otherwise put your eyes out of focus and you can see what might and might not be visible on a crap monitor.

Loose a few people? Only with one of these..

But what about the cost of the spokes?!?!!?! I would have used your calculator in good faith that it was accurate. What if i ended up with £40 worth of unusable spokes that I couldn't get a refund on?!!?!

I am forcing no-one to use this and encourage discussion about it on here. If you find something that isn't right, put it in this thread.

As I said, the calculator uses the same formula as Damon Rinard's one, which has a large amount of credibility and was recommended by Sheldon Brown.

you try and do something useful.. put in a disclaimer.

nice work.

You are buying from a shitty shop.

I'm only winding you up, but anyway, I think you should put in a disclaimer, that you are not responsible for the content, accuracy etc. and that it's intended as a guide. Not that I think it's actually going to turn out inaccurate, but you know, it's always good to have a disclaimer, just in case.

Anyway, now I know the correct spoke length for when I buy a pair of open pro's for my formula hubs, so.. cheers!
