Spoke Size / Spoke Length Database - What size spokes do I need?

What rims are they -- any stickers at all?

Remerx aero rims:

I can't see the ERD measurement on their website or anywhere else.

• you could just phone them for a final answer...?
  

they look similar to open pro's, so 290mm ish

they look similar to open pro's, so 290mm ish

how 'ish' can I get away with? Is that length using the Miche hubs?

Ta

288-292mm, yes

rightyho, so I'll order some 290mm, and if all goes tits up I'll know who to blame :D

oo just thought, before I do anything stupid, will I need different lengths for the front and rear wheel?

no, although you will need to dish the rear if using the miche primato single sided hubs that cyclebasket sell ;)

can't blame me i'm a facet of your imagination

Ok, It should be fun for my first time round... I'll let you know how I get on (more likely pleading for help)...

Quite a few seem to be building wheels at the mo, thought it might be an idea to check down what length spokes as a quick lookup for people wanting to do the same build and to lazy/stupid/busy/lacking info* to use a spoke calculator

Delete as appropriate

Front: Phil Wood High flange, Mavic open pro, 32h, X3 = 290mm
Rear: Phil wood HF double sided, Mavic open pro, 32h, X3 = 290mm

Please feel free to join in and and your own, or leave a slightly useful thread for anyone building the exact same thing I did.

Front: Phil Wood HF - DeepV, 32h, radial = 258mm
Rear: Phil Wood HF DS - DeepV, 32h, X3 = 280mm

I think Arup's already got a massive one, seem to remember him emailing me it last year...

clever boy...

Good reference point for people who don't trust spoke calcs, although no substitute.

Front: Diatech Gran Compe Track - 32h, Deep V, 3 cross = 281mm
Rear: Diatech Gran Compe Track - 32h, H+Son, 3 cross = 268 mm

I think Arup's already got a massive one,

Tee hee

@ Gizmond: PM me your email addy, I'll send you the Excel file Arup sent through...

I've got a (massive) list of specs for the more popular hubs on my wheelbuilding site

http://yogarup.com/wheels/hubs

Working out the spoke lengths is then fairly easy using the Damon Rinard Spocalc spreadsheet.

Also this year I've been logging all the wheels that I've built and you'll find that on my blog

http://arupdesigns.co.uk/blog/archives/category/wheel-log

There are spoke lengths included for each wheel, number of holes and cross pattern.

Laziness is good because it makes us come up with ways to keep being lazy.

I'm thinking about "translating" Damon Rinard and Arup's data into a web application, where you only type in your hub and your rim and - voila - it spits out your spoke length. I'm by no means an accomplished wheelbuilder but I like programming web apps.

Does something like that exist already?
Would that be useful or do people distrust these things and want to calculate themselves?

Arup, is the data on your website published under a permissive license?

the complexity of some of those spoke calcs can be a bit intimidating
i like the idea of just typing rim and hub type for spoke length rims and hubs

FFS it's not hard to calculate spoke length

But its easier to not have to, if someone will tell you what it should be :-)

(although I am sure I would probably end up double checking with a spoke calc anyway)

trying to work out spoke lengths for 700c h+son (557 erd) and miche primatos and was wondering wether anyone could double check my calcs before i order spokes?

I worked out rear 3 cross to need 268.16 using
http://yogarup.com/wheels/hubs
http://www.unicycle.uk.com/SpokeCalc.asp

the calc couldnt work out radial (unless radial is 1 cross or im being stupid?) anyway I used gcse maths pythagorus theory to work out i would need 258.8, which is very likely to be wrong.

do these sound ok?

cheers

radial is 0-cross
