Spoke Length Tech Question
Building a wheelset and using WTB KOM Tough i45 rims with an ERD of 572. When I used a spoke calculator online the only rim size it had was an i40 with an ERD of 571. It gave me spoke measurements for the rear wheel of 578 right and 577 left. I'm wondering since I'm using the same style rim but in i45 can I still use the same spokes given the ERD is different.
My second question is... I only have 276mm spokes. Can I still use this even though it specifies 277?
Thanks

I'm not a bike shop wheel builder, just an amateur willing to share my experiences, and help bump your post.
If you use the DT Swiss calculator, and just use an arbitrary rim, the ERD 571 will probably come up 1 mm shorter than an ERD572. You might need 278's.

And your existing spokes are another mm shorter than that? Being off by 2mm is probably on the ragged edge of being too short,
