Done a little research on the Velocity Tandem Wheelset

700C Deep V semi aero rims

Sealed cartridge bearing Velocity hubs.

Shimano 8/9 spd compatible.

The rear has 4 bearings, the front has 2.

Rear Wheel : 1316 grams

Front Wheel : 1128 grams

Weights are without quick releases.

Available for 140mm and 145mm axles, in a variety of rim and spoke colors.

Anyone have any experience with these?
