Redline 401 Cranks Single Pinch Full Wrap 185mm BB 42T chainring bubble font. Really nice shape. Single pinch full wrap. Hard to find 185mm arms. They have been used but have aged nicely. No dents in the arms. Pedal threads are perfect. The chainring is a 42T, straight with a little blem by the script, shown in the pics. Double dimple axle with sealed bearings, one of which could be replaced, but still spins smooth. Perfect for that early 80’s BMX build, especially if you have a cruiser.
