Henrik Melph,
Verified purchaser

This was my second bike from Sigma and the total experience remains incomparable, every step from ordering to delivery and dialing it in for me was attended to by Leon with great care and attention. He provided advice and input along the way and really made it hassle free and very pleasant. The bike is the raciest lightest gravel bike I have had, incredibly quick especially over fast and flowy hard packed gravel. Love it. And Sigma delivered the first bike of new model in the country to me! There is really no need to shop anywhere else

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.
