Originally launched by leading manufacturer Trek Bicycles, Trek Travel is now an independent company, but they still maintain a close relationship and have always been at the hardware forefront in terms of quality.
Unlike many other companies, they do not charge an upgrade fee and simply start with the best, the Trek Domane SL 7 road bike, a top full carbon frame with Bontrager Race Lite TLR wheelset and Ultegra Di2 electronic shifting (though they do offer a $200 wheel upgrade to Bontrager Aelous D3 carbon wheels).
