Swinnerton Low Pro??
I have a Swinnerton 26" front wheel 700c rear wheels which are tubs Low Pro, if has a mix match for Campnag and Shimano like Dura Ace rear mech, 7 speed block, Campnag Delta brakes and matching levers, Turbo saddle, time pedals, and a nice set of Cinell bars.
The bike can be viewed in the £how much is it worth" page - Look for Swinnerton Low Pro.
