Need help calculating spoke length

[Maor1237]

Hi, I need help calculating the length of spokes. Does anyone know for sure what length I will need to order? I have the specifications for the hubs and rims: Hubs: https://dartmoor-bikes.com/hardware/hubs/reel-pro-v2-singlespeed https://dartmoor-bikes.com/hardware/hubs/reel-expert-front Rims: https://the-rise.com/products/octane-one-26-32h-rim-solar-pro

For example, I got 268 left and 266 right for the rear wheel, am I right?

Another question- where can I buy dt swiss spokes in good price? (I live in africa so i need online with shipping) Thanks a lot

Daft question but I presume you're asking because you want to order rim, hubs and spokes in one hit? If you're familiar with doing your own wheels you'll know it's best to do the measurements necessary for the spoke calculator yourself i.e. you have the hubs and rim for a proper hands-on measuring session. That way you don't order a shed load of incorrect length spokes. If it were me and I'd made up my mind what hubs and rims I wanted, and decided on the number of spoke holes, I'd buy those first and wait for them to turn up so they can be measured properly. Then measure everything again. Then you ought to be ready to order the spokes. I agree the ERD for the rim appears to be there online but I can't see the hub measurements that you need for the calculator.

I got this rims and hubs. Now I need to order spoke and nipples

For spokes I usually ask Malc at the cycle clinic.

OP - you have the rims (ERD=536mm, 2mm offset asymmetrical drilling) and hubs and their specs.
Do (check) the measurements necessary for the spoke calculator, yourself.
Calculate.
If you feel a cross check is necessary, use a second calculator (bit like checking a second or third weather forecast).
Check current 'stock'.
Order (silver/black, double butted or plain gauge, (brass) nipple length.

What spoking pattern are you using for the rear wheel? If you go for 3 x cross then the calculator I use comes up with 259mm both sides based on 32 hole rim, ERD 536mm and the measurements you've shown above for the rear hub. So I wouldn't order your spokes just yet untill you're doubly sure.

Ok thanks for sharing. The pattern I want to use is x3 cross. So I have to measure myself. Can someone recommend for good video for that?

If you don't know the basics how do you plan building wheels? Why not get your local bike shop to do it? If you're he'll bent on doing it yourself try YouTube.

Heres how I built my first wheels.

I watched multiple videos until I understood the whole process beginning to end.

I bought rims and hubs.
Measured and remeasured their dimensions.
Used three spoke length calculators.
Checked all dimensions again the next day.
Bought spokes.
Assembled wheels. Took me two days.

Put on tape, tubes and tyres.

Ride the bike for around 5000 miles.

Is his calculator reliable?
