1991 Trek 520 Touring frame (Made in Waterloo, USA lugged cro-mo frame), converted to a Gravel Grinder. The bike is relatively quick for a touring frame and handles more like a CX bike with the 429mm chainstay, but can still handle a 42C tire without finders, 40C with fenders.
All new parts:
Velocity Dyad / Shimano 105 hubs, custom wheelset
700x40 Maxxis Rambler DC/EXO TR Gravel
Rival 1 crankset 42T, 1X11
Apex 1 rear derailleur, shifter/mechanical levers
Paul Motolite Brakes (yes they work with the Apex levers)
Thomson Elite Layback Seat post
Brooks B17 Imperial
Salsa Guide Stem & 46cm Woodchipper bars
Speedplay Drillium flats pedals
Rides like a dream!
