What should a cross-country saddle do? Something like this... allow unimpeded pedalling, be soft enough to cope with long hours in the saddle and be firm enough for you to exert full power to the pedals.
It also has to be lightweight. A tall order, but not so tall that THE's Lux saddle can't manage it. It has Ti rails, a thin, flexible base and a tan real leather cover with a Louis Vuitton-esque embossed pattern. Very now, darling.
