Share 'Williams Cross Tubulars'

I got a pair of Williams alloy tubulars, but the rims are 19mm wide...which is fine, except all my other 'cross rims are 21mm, so I'd have to adjust brakes every time I switch.http://williamscycling.com/cyclocross_tubular.htmlAnyone want to buy these from me before I send them back? Great 'cross wheels. Brand new in the box, make an offer.--John Verheul505-231-1665 (cell)john@jbvcoaching.com
