Pictured below are two wheelsets built with 650b Pacenti Brevet rims, one built in March and another more recently. I was happy with the steadiness of the rims and would recommend them if they meet your needs. The first set uses Campagnolo hubs; SON and Shimano hubs on the second. The hubs were supplied by their owners except for the SON dynamo, which I provided. The Rene Herse (formerly Compass) tires were provided as well, an option for wheelbuilding customers.
