On the topic of ERD:
What is the best tool/way to measure it?
Right now I'm using two spokes cut to a specific length and joined together with an elastic band.
Pulling the spokes and the elastic band through the spoke holes multiple times per rim is kind of a pain though. If I use too much electric tape on the joint it doesn't fit through the spokes holes, not enough and it rips apart when pulling it through.
I've found a specific tool called "Rim Rods" made by Wheelsmith but it seems to be discontinued and only available from US online shops.
Are there any alternatives? Or does someone know where I can get the Rim Rods without ordering them from overseas?
