    582 is our place holder ERC, but it's best to measure yourself. Their stated 580 ERD is measured in a funky way that doesn't include nipple heads and seems wrong anyhow.

    Is ERC the same as ERD? I wonder why there is so much difference in ERD between Pacenti SL23 (589 ERD) and Easton R90 SL? There is only 1 mm difference in rim depth. I was hoping I might able to reuse my spokes but I think they will be too long.

    ERC is the fat fingers typing on an iPad version of ERD.

    Your spokes will be too long. For example and from memory, a set of SL23s laced 24/28 radial front and 2x/2x rear with WI T11 hubs is 277mm front, 282 non-drive, and 277 drive. A set of R90SLs with same hubs and lacing is 274.5mm front, 280/275 rear. We use a spoke cutter/threader so our spoke sizes are in .5mm increments. This is not broadly necessary.

    Part of the ERD difference is that the Easton has a thicker spoke bed. They don't crack.

    Dave,

    That is what I thought. I am going to order the rims and measure the ERD myself.
    What spoke tension do you recommend on the drive side for the Easton rims?

    We try to get at least 55 on the non-drive side. Some hubs need more drive side tension than others to do that. 125 should get you there with most good hubs.
