BSCTools ERD Rim Rods to calculate ERD (Effective Rim Diameter)
Updated 13th January 2022:
Updated 7th January 2022:
– no calculation required, just read off the scale
– laser engraved so you can read the ERD measurement where the rods overlap
– stainless steel for minimal rod flex
– chamfered rod end for good fit into nipple eyelet
– small rod end so offset rim eyelets have minimal impact on a straight measurement
– maximum ERD that can be measured 700mm (or 500mm with shorter version)
There is a PDF manual for the ERD Rim Rods at https://bsctools.co.uk/manuals
