These one of a kind lug patterns come straight from London inspired by the strict love of bicycles and a music shop. Hetchins Cycles date back as far as the 1920's and made a name for themselves among the racers in the 30's. The patented "rear vibrant triangle" design and signature head tube look make them unique to any bicycle enthusiast or collector that has a good chunk of change in his wallet.
