Mr Motivator Posted November 2, 2005 Report Share Posted November 2, 2005 Get out a tape measure and work out the Effective Rim Diameter, and then with the hopetech.com spoke calculator your away :D Link to comment Share on other sites More sharing options...
Urpedigreechumdog Posted November 2, 2005 Author Report Share Posted November 2, 2005 Even though the spoke holes aren't central? They are off to the side :D Link to comment Share on other sites More sharing options...
Mr Motivator Posted November 2, 2005 Report Share Posted November 2, 2005 Well that shouldn't make a huuuuuge difference. You can allow a little like that :P For example, all my spokes on my front wheel are 2mm too long, theyre fine :D Link to comment Share on other sites More sharing options...
Urpedigreechumdog Posted November 2, 2005 Author Report Share Posted November 2, 2005 OK, well i'll give it a go... Cheers :D Link to comment Share on other sites More sharing options...
Mr Motivator Posted November 2, 2005 Report Share Posted November 2, 2005 Make sure you get a ERD correct though :D Tart has a guide on here somewhere of how to do it correctly :P Link to comment Share on other sites More sharing options...
dave85 Posted November 2, 2005 Report Share Posted November 2, 2005 Spoke lengths can be a bit difficult, but can be sorted easily using the advanced spoke calculater, simply do it one side at a time (Left hand side = non drive side of the hub ) and where it says rim offset, just put in (in mm obviously, half the width of the rim that it's being laced to), and it will take the offset into account. Or, if that's a bit too complicated for you, I'm sure if you're buying the spokes from tartybikes.co.uk, Adam will be happy to help. When in doubt, leech off fatmike :D :P Link to comment Share on other sites More sharing options...

Phatmike Posted November 2, 2005 Report Share Posted November 2, 2005 Why? so i get an answer of 'erm i dunno, sorry mate'. I was tired + busy. :P What Edd quoted is all you need to work it out, since I wasn't very helpful the other evening, I'll help a little more now. http://www.sheldonbrown.com/rinard/spocalc.xls Get that. Enter the hub measurements. (Easy to find, should be in the spreadsheet) Enter the ERD of a mavic X517 (It's in the spreadsheet :D) Then, (like Edd correctly quoted) under offset spoke bed, enter -11mm. Just realising now, looking back at my post that I forgot to mention it is a minus, as you'll want the spokes to cross over (like a sand timer), not for them to not cross over, (like a trapezium). :D You should be sorted with that. :P Mike.

Urpedigreechumdog Posted November 7, 2005 Author Report Share Posted November 7, 2005 No Dr. Smartarse, my comp has not got Excel so the spoke calc does not open up, so i can't do it. Would anyone care to help instead of try and take the piss? Link to comment Share on other sites More sharing options...
