Horizontal sliding dropouts let you choose between singlespeed or geared set-up for a personalised ride Trek Bikes. I rode the ticket dj for a number of years and put it through constant abuse with no issues! This year I got picked up by a frame sponsor so no longer needed my Trek. This frame is brand new, never been built and has only been out of the box to take these photographs. FSA Headset components. Zip ties for brake/gear cable management.
