I've been considering building an all-round wheelset using some single wall Rigida rims which I've been given. You know, something you could use for commuting and touring (except expeditions!). Reliable wheels, in a word. Rims are Rigida AS 26F and hubs are old 6sp XT (with a 7sp freehub body). At 500+ grs. and being heat treated, the rims seem to be sturdy to me. But, are single wall rims good enough for this job?
