This is an experiment. 16 spokes on a 32 hole hub/rim. The spokes will be configured in a paired configuration at maximum tangency to the hub. Sizing the spokes for 32 4-cross is the same as 16 2-cross, so that gives an idea how the wheel will come together. Two spokes will meet the rim from the forward side of the hub, then two holes are skipped, then two spokes will meet the rim from the rear of the hub. I will be using butted 2mm spokes and the new DT hex nipples to handle the increased tension in the system. | This is an experiment. 16 spokes on a 32 hole hub/rim.

This is a concept bike that I'm trying out. 650c wheels and disc brakes on a fixed gear drive. Designed more for slow speed manuverability and safety than full speed road handling.

650c Paired 16 spoke wheels
This is an experiment. 16 spokes on a 32 hole hub/rim. The spokes will be configured in a paired configuration at maximum tangency to the hub. Sizing the spokes for 32 4-cross is the same as 16 2-cross, so that gives an idea how the wheel will come together. Two spokes will meet the rim from the forward side of the hub, then two holes are skipped, then two spokes will meet the rim from the rear of the hub. I will be using butted 2mm spokes and the new DT hex nipples to handle the increased tension in the system.
