Spoke length help

clogg

Hi, i'm looking for some help ordering the spokes for a wheel build, I have tried a couple of online calculators and have had conflicting results. I don't have the rims and hubs at the moment to measure. I was hoping someone would have the details to hand as its a reasonably common build.

Details are : Mavic open pro 36 hole rims
Shimano 105 5700 hubs
3 cross lacing

Any help would be appreciated

Some advice here WRT open pro rims and 105 hubs but for 32 hole drillings .

Not sure if same applies for 36 hole but I'm sure Ugo or Cycleclinic will be along to help out eventually

Thanks I was looking at that thread. Bit unsure myself if there is much difference.

293 front, 292 and 290 rear

Thanks ugo, I cant see a 293mm spoke listed, should I go for 294mm or 292mm for the front (Using Dt swiss 14mm brass nipples).

I used 294mm.

You can quite easily get away with 1mm difference from the correct length

294 and 12 mm nipples

Thanks a lot for the quick replies spokes ordered.

For next time there are a few spoke length calculator websites, one I've used a lot with repeated good results is Prowheelbuilder, rounding the length down from the decimal has consistently worked for me.
