Trek Domane SL 6 105 Di2 Gen 4 Road Bike

The Trek Domane SL 6 105 Di2 Gen 4 Road Bike is a lightweight endurance bike designed for comfort, efficiency and performance over long distances. Its 500 Series OCLV Carbon frame delivers a smooth, stable ride with aerodynamic tube shaping to help you go faster with less effort.

A wireless Shimano 105 Di2 electronic drivetrain provides precise, reliable shifting, while alloy wheels and handlebars strike a balance between value and performance. Ideal for riders who want modern tech and all-day comfort without stepping into the top-tier price range.

Costa,

Upgraded from a hybrid to an endurance road bike and it has been a delight. Super smooth electronic gear changes, light and really comfortable. Thanks Ralph for the guidance along the way.

About Trek

The best bike, ridden everywhere.

Founded in a Wisconsin barn in 1976, Trek has grown into one of the world's most recognised bicycle brands without losing the obsession that started it all: build the best bike, ride it further, share it with everyone.

Trek believes the bicycle is a simple solution to many of the world's most complicated problems. Every bike Trek builds — from the Madone race weapon to the Marlin trail bike — is made with that conviction. More riders, more often, on better bikes.
