Modern gravel bikes have come a long way, doing their best to catch up to what a hardtail can do. When it comes really ripping real trails though, there's no replacement for a proper mountain bike. And when it comes to hardtail mountain bikes, it's tough to think of a material better suited for it than high quality titanium.

The MT-1 is built from 3A/2.5V tubing and can be configured nearly any way you want. Want a race ready 29er XC bike? You got it. Want a slacked out, long forked 27.+ bike? That can happen to. It can even be built as a 26" pumptrack bike if that's what your heart desires.

Like every Mosaic, an MT-1 build is a custom process, and we're here to make it easy for you. If you've been dreaming of a custom hardtail that will last you a life time, we're only a quick phone call or email away.
