This wheel set came off of a Norco Tactic 505. The PO removed what small decal there was to identify what they are, so, all I can offer is the breakdown on the Norco site below. They are in excellent condition. SRAM cassette included (11-26). Continental 700X25c tires. Thru axel hubs. Roll very nicely. True. Thru Axel skewers not included.
