We took the Rolf tandem wheelset off the Co-Motion Robusta and have been runing my hand built 36 spoke White Ind racing hubs with Velocity deep V rims. We find that they perform really well and we can not tell a hole lot of diffrence in general between the sets other than the routine maintanance such as wheel trueing on the Velocity wheelset is easier, they also have a wider braking surface on the rim wich make brake shoe alignment a lot easier, also they weigh a few grams more than the Rolfs wich is no big deel to me. :D

Take Care All, :)
