Was going by the published Rigida Chrina ERD from SPA et al but also now read that ERDs of 607 is being stamped on them. Rigida is now also Ryde?

My own build of 296mm spokes on a DA7800 front hub (and a previous successful rim transfer) using the Open Pros was based off 605 and the DT Swiss and Mavic's own spoke calculator apps use 604, so 602 seemed an outlier unless they have changed.

Picked up an Open Pro in Sigma Sport today (currently way cheapest UK price @ £39.99 for all colours and including the CD version BTW) and whaddaya know they are 602 as was the worn out Open Pro it is replacing.
