measuring spoke length.
So i have two wheelsets i want to relace
I dont know where to start, I will be getting the wheels built at the LBS but i want to purchase the spokes and nipples
I have 1 fulcrum racing 7 front wheel that has a dent in the rim, i want to use the hub and lace it to a
kinlin xr 270 20hole
I dont know what spoke length
I also have 50mm clinchers that i want to get new Bladed spokes for, But i dont know how to measure the spoke lenght. Any pointers?

For same rim/same hub rebuild, a Park Spoke Ruler is nice to have:

For the Fulcrum/Kinlin combo I'd probably just let the LBS pick out spokes. OTH if you have calipers you could measure hub specs and then plug in the rim's ERD (ERD: 587) to one of the spoke calculators out there. I've had good luck with Damon Rinard's spreadsheet I got off of Sheldon's site. There are online ones too, though.

If you want to calculate spoke length do as suggested above. if you want to measure spoke length, they're measured from the inside of the elbow to the end. If you have a 12" or 300mm+ ruler who's graduations go to the end, simply hang the spoke over the end and measure.
BTW- I don't suggest buying your spokes then letting the LBS build. Two reasons.
1- you might get the "do you bring your meat to McDonalds" speech. The shop should be able to buy spokes cheaper than you can, but in any case potential profit on spokes is often factored into the labor cost calculation, so your way could end up being costlier.
2- if you supply the spokes, you're responsible for their selection and especially the length. If it turns out to be wrong, you'll eat the cost of buying replacements. The shop would also be entitled to charge for the wasted and added labor of lacing then taking it apart, though that would be less than the build cost. Letting the shop supply the spokes makes them responsible for the calculation, and protects you from added costs if there's an error.
