Mountain bikes are the Summit rack’s best pals, but it won’t turn its’ nose at certain gravel or drop-bar companions. We designed the Summit around adult mountain bikes, so it’ll happily carry your 26”-29” wheeled mountain bikes with tires anywhere from 1.9” to 5” wide - that’s right, fat bikes can come along for the party! When it comes to our drop-bar steeds, compatibility is more of a dance. See the next FAQ for further details on carrying drop-bar bikes in the Summit.
