Bike cargo rack support arm

Bike rack holder adapter for Marin Ignacio and Axiom slim rack.

This will work for anyone tired of buying aluminium connectors that inevitably break. I tried a version that is much smaller and didn't have smooth bends, it lasted at least one season of riding.

Learning from the failures I made this version slightly thicker with smooth curves instead of cylindrical joints.

Do not over-tighten the bolts as the adapter will eventually crack.

Hardware used with this

Attaching the bike frame

1x M5 30mm bolt (35mm also fits, as pictured)

3x M5 15mm washers, but any large washers will do

1x M5 Locknut

Attaching the rack

2x M5 16mm bolts

2x M5 Locknuts

2x M5 Washers
