Bontrager/DT Swiss hubs. These were principally the original 240 hubs. These hubs were made before thru axles were quite common and can’t be converted with new end caps (possibly ready to convert if replacing entire internal axle assembly, not sure).
-They use the DT star ratchet freehub, so can easily be converted to accept an 11-speed road cassette.
-These weigh 1640g as shown, with rim tape.
-Hubs had little or no use within the original wheelset, and so they were recently built up with modern Stans Crest MK3 rims. They have got not been ridden since being rebuilt.
