American Custom Bicycles in Steel, Titanium and Ti/carbon mix

Endurance Racing & Exhaustion


There exists a realm where pain is a given and finishing the ride is the ultimate prize. We ride through blazing hot sunlight and unknown midnight darkness. Singletrack pathways redefine distances as we reach terrain rarely conquered. Sometimes we race to cover distance. Other times to prove our worth against the clock. Six, twelve, twenty-four hours. Sometimes more.

One Mountain Bike

Many Choices



No one wheel is ideal for all applications. 29er. 26”. 650b. 96er. A decade ago, when we built our first 29er prototype, wheel and tire options were woefully limited; we had to use road hoops to get us going. Fast forward to today: we design bikes for all wheel and tire sizes. We ride them. We race them. We experiment with them. Each wheel size demands geometry adjustments. We‘re comfortable with the tradeoffs that each category requires.



Whether you seek the purity of off-road single-speeding or you just enjoy the quiet simplicity of one gear, Seven offers a variety of single-speed solutions: belt drive, slider dropouts, eccentric bottom bracket, or horizontal drops. Who would have thought that a simple single-speed had so many options? We can help choose the single best option for your single-speed passion.



Faster riding through better stopping. We optimize the design with whatever braking system you prefer. Standard hydro disc? Sweet. Prefer an easy to maintain low-mount cable actuated disc? With pleasure. Lightweight purity of V-brakes your preference? Absolutely. Want all three mounting options? Okay…we can do that. Those who can stop faster can ride faster.



We offer all of our mountain bikes with three bottom bracket options. The most popular is the 68 mm threaded bottom bracket. For those who have something else in mind, we offer the BB30 system to work with the latest oversized spindle. We even offer an eccentric bottom bracket option for single-speed chain tensioning duties.
