Thanks LWaB . I am in the process of striping it down , the axel is going on my old Claud butler frameset re rimed with 622 . I was going to fit the rims and tyres on a friends bike , but the rims are too narrow according to the tables . I would feel happier fitting wider rims or fit different tyres . He just use the bike to get about with minimum maintenance . So the tyre pressures will only be checked when I look at it once a years .
