I handbuilt a few sets of cyclocross disc wheels before they were “legal.” Now I think this is just ready to explode with the upcoming season. More bike manufacturers will be debuting disc ready cross bikes at seasonal trade shows. Hydro shift/brake levers from top component makers can’t be far behind. Without a brake track, disc rims are lighter at the outside of the wheel, where saving weight matters the most. Not to mention all the advantages of having disc brakes over rim brakes. For those on a budget, Shimano disc mountain hubs are in stock and on sale. Order today for the best selection.
