Having broken my leg, I've sadly given up cycling and have a set of Mavic Cosmic Ultimate Tubular wheels for sale. They have done about 1,500km and are about 18 months old. They come with Continental GP4000 II tyres but no cassette. The hub will take Shimano or SRAM. New they were EUR2,999 (S$4,600) but I am open to sensible offers around S$2,950.
