Cycles Imholz Sport, 1977, Switzerland
History & Specifications
Alois Imholz runned in St. Gallen, Switzerland his own frame building factory. He produced a wide selection of bicycles from unicycles to 3-speed city bicycles, cycle ball bicycles, art bicycles to racing bicycles. The classic color of an Imholz bicycle was red. From the 1930s into the 1950s Imholz was the importer of Reynolds tubes and his frames were built with those tube sets. He also used the hole set of Georg Fischer (+GF+) malleable cast iron fittings from lugs, fork crown, bottom bracket to drop outs.
This well cared of Imholz Sport was handed over by the first owner. It is set-up with the complete 1. generation Shimano Dura-Ace Component Group. The Shimano production codes stamped on the components are mostly from 1977 or little earlier so the I assumed the Imholz Sport was built 1977.
The bicycle was carefully cleaned, all ball bearings (hubs, bottom bracket and head set) were cleaned with solvent, regreased and adjusted. Replacment parts are a longer 3 ttt stem, the 3ttt Competition handlebars, the handlebar tape and a NOS set of Shimano Dura-Ace brakelever hoods. New tubulars, a new 6-speed freewheel and a new KMC chain completed the restauration..
