Replacing spoke

ok, so i finished my first build 2 days ago, went for the first ride and all good. Got bike out this morning and discovered a broken spoke on the rear (drive side).
Now after having spent about a month avoiding the bike shop and doing a complete build myself, dont really want to have to wait a month to get them to replace a spoke. Also having sworn to myself i wasn't spending another penny on the bike (i just had to add a brooks saddle as a finishing touch)...

Bottom line is I want to replace the spoke myself, having never done it before, how easy is it? is it best to rebuild the whole wheel or can i just do one spoke? the wheel is still true. What tools do i need? any tips?

the wheel is a mavic open pro on system ex flip flop hub. I weigh 100kgs so not going to ride the bike till i replace the spoke!

go get a spoke the right length. you can replace one no worries. if the wheel is still true then it's even easier.
just pull the old one out and put the new one in with the same lace pattern (if it crosses another spoke on the inside then the new one should aswell) you'll need a spoke key to tighten the nipple.

cool, thought it would be relatively easy. Only prob is i cant find a system ex hub on sheldons spoke calculator. Will my local bike shop know the spoke length? (cavendish cycles)

Wouldn't worry unduly about riding on a broken spoke. When riding across Canada my gf rode about 200 miles on an 80lb bike before we could find a shop to get spokes from. It lasted a fair while after that.

Just remember to keep an eye on the new spoke so that it stays taught as it beds in.

Undo spoke, take it to shop, ask for replacement. Buy a couple so that you have spares.

Easy.

hmmm... bike at home, me in city! was hoping to get the bits at lunchtime, go home, fix bike... guess i could remove spoke tonight and bring back in tomorrow. Just another day off the road! i could ride with a broken spoke but i've found on my mtb that doing this can put the whole wheel out, and i'm sure my skills don't stretch to truing a wheel just yet!

Did you get the wheel from a shop? If so they should be able to measure against another one. If not you could google the wheel and see if you can get some specs off the company.

nope, bought the wheel second hand off here, so its about third-hand now! check this thread http://www.londonfgss.com/thread7226.html

Out of luck I think unless someone here has the specs at hand.
