BSC - ERD Rim Rods

BSCTools ERD Rim Rods to calculate ERD (Effective Rim Diameter)

Note: Single 350mm rod now available which is laser marked down to 400mm - an upgrade if your ERD rods are marked to 550mm which was the original laser etching

Note: Rods are supplied as a pair (2 rods), with 2 clips that can hold them together

Available in two lengths:

• 700mm (2 x 350mm rods), one plain rod, one with ruler markings from 700mm down to 400mm). Suitable for 700c, 650c wheels
• 500mm (2 x 250mm rods), one plain rod, one with ruler markings from 500mm down to 270mm, for smaller wheels

Features

• no calculation required, just read off the ruler scale where the rods overlap
• can still measure straight for ERD on offset rims
• stainless steel for minimal rod flex and long life
• two clips supplied so you can secure the rods together - you can measure the overlap manually if it does happen to be longer than the marked ruler
• chamfered rod end for good fit into nipple eyelet
