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

Hey buddy,

Try this, it's the original spreadsheet that the EDD spokecalc site is based upon;

http://sheldonbrown.com/rinard/spocalc.htm

Hope that helps!

EDIT - Although i'm not sure it will have the likes of chukkers in there :-s But if i remember correctly there is an option to enter your own information.

Used some of the spoke calculating links above to calculate LF double fixed Phil woods 36h to Campagnolo Omega V's given me a calcualtion of 289.1 for rear and 289.6 front and looking to go for 3x for both is it best to go up to 290mm spokes would this be ok, or best to go one down to....?

290 will be fine.

Remember to add to the list once successfully built!

Nice one, will do

dura ace 7800 to mavic open pro 32 hole 3 cross

what spoke length would i need ?

^I built that exact wheelset

Dura Ace 7800 32H hubs
Mavic Open Pro rims
3x build with Sapim CX Ray for front wheel and rear non-drive side,
Sapim Race for rear drive side
48 296mm Sapim CX rays and 16 294mm Sapim Race

nice one i presume the 296's would be for the front wheels and non drive side ?
thanks
condor here i come
new wheel tomorrow !

Sapim CX Ray for front wheel and rear non-drive side,
Sapim Race for rear drive side

What's the reasoning here? Why not CX-Rays on the rear drive side as well?

Ran out of money...?

I've just calculated a wheelbuild as Front 239.5 and rear 238.5

The shop doesn't have loads of spoke choice and I have to choose between 236 or 242.

Which should I go for or should I look elsewhere?

Cheers

Look else where if i were you, the 236's will come up too short (you won't be able to get the spoke into the nipple) and the 242's will be too long and potentially you will run out of thread on the nipple with the spoke poking thru into the rim.

EDIT - 242's might work on the front but i'd suggest getting 240 front and 238 rear. Have you tried cyclebasket?

Sigh

I just had a look on SPA cycles and a general google suggests they will cost alot. The benefit of going with either 236 or 242 is that I can get them trade price which is a massive boon. Could I go for a longer nipple to make up the difference?

Edit: also no jot on cyclebasket

Hmmm longer nipples might work but i've always opted for the standard 12mm.

I built a wheel for a mate at work last week and he bought 290mm spokes, i couldn't get about half of the spokes to even engage with the nipples. I measured the hub and redid the calc and it turns out he needed 294mm. It made the world of difference.

Like i said longer nipples may work but i'd rather build it properly for the sake of a few quid - incidentally how much are spokes at trade price as opposed to webshop price?

I've now sorted it with the right size spokes and not a silly bodge.

I don't know the exact difference in price for the spokes, although with the rest of the stuff it was roughly just over %30 reduction on RRP.

Good to hear you've sorted it buddy. Didn't mean to sound so negative but when building your own wheels it's one less thing running through your head if you know the spoke lengths were bang on and you're not worrying about bodged nipple lengths/incompatible spoke lengths!

Definitely true. Thanks for your advice.

dura ace 7600 double fixed low flange to mavic open pro 700c, 32h 3x, anyone?

anybody got a spoke threader I could use?

bump, anyone?!

Checking Spocalc now... can you find out if Hilarystone will be at the Cycle Jumble this Sunday in return?

Ok, hubs not listed by 7600 on Spocalc, and no useful info on the techdocs either.

http://techdocs.shimano.com/techdocs/blevel.jsp?ASSORTMENT%3C%3East_id=1408474395181679&FOLDER%3C%3Efolder_id=2534374302051957

result: http://www.yogarup.com/wheels/hubs

assumed ERD of 605 for the open pro, hub numbers based on yogarup hub info, and using his mighty quick Spocalc widget:

Front

• Radial 270.0 mm
  
• One cross 272.9 mm
  
• Two cross 280.8 mm
  
• Three cross 292.2 mm
  
• Four cross 305.1 mm
  
  

Rear

• Radial 269.6 mm
  
• One cross 272.4 mm
  
• Two cross 280.3 mm
  
• Three cross 291.8 mm
  
• Four cross 304.7 mm
  
  

Best get a second opinion though, or at least check the measurements yourself with the hubs and rims you're holding. I'm just using the numbers I found on the web afterall, and I'm assuming the flange measurement on yogarup is a low one (although 67 might not be that low - bikeforums suggest might be 44, but then the c-flange measurement changes too?)

Ah, thank you very very much RHB your a gent, will head down to the LBS and confirm later...I return, I gave Hilary a shout and he will be at the Jumble on Sunday however he won't have much, if any, stock with him. Cheers!

Hope LBS can help with measurements.

re jumble - I was only jesting as seeing your post had distracted me from asking, but cheers for asking on my behalf nevertheless!

So I am planning to relace my Miche Pistard WR rear wheel into a Dia Compe Gran Compe double fixed hub and needed to find out the spoke length.
The Dia Compe hub's data is easy enough to find. The problem is the ERD of the Miche rim is a mystery, tried google and several spoke calculators to no avail. Emailed Miche but it seems unlikely they will reply.
Is it possible to somehow measure it myself? Or calculate from the official rim depth? Or it won't be accurate enough?
