may even have your hub and rim there already.

Nice chap, based from the spocalc program and is the modern easy to use online version. Helped by the author of spocalc iirc.
Hit the How To measure link there to find out how to measure.

Just tried this calc - I would have expected front spokes to be the same length - but left and right are different???
And for the rear hub - the left and right spokes are pretty much the same??
Or is this cos these are disc hubs - as opposed to good ole non-disc hubs?? :idea:

I've also found a cheap source of DT spokes - looking like £20 for 66 DT Comps.

If the flange diameter is the same left and right at it is is a non disc hub the front sproke lengths left and right will be same.

For a rear hub left and right spoke is normally different but on some disc hubs they can be nearly the same.
