LIGHT & AERO COCKPIT

We reached out to up and coming Chinese carbon brand EXS to help us develop an integrated handlebar system. The result was a sleek finished product thats also light and aero.

ATTENTION TO DETAIL

We spend hours obessing over the small details. From the custom stem cap bolts to inspiring quotes on the thru-axles the design features will impress those with an eye for detail.

VERSATILE TYRE CLEARANCE

With clearance for up to 35mm this bike has tons of versatility. Fast road rides during the week on 28mm, swap out to 35mm for  some adventurous exploring on the weekend.
