Why We Love It
The predecessor to the radical Andean Tri bike, the Serios is a more traditional design that fits UCI regulations and could double as a speedy Time Trial weapon. While some triathlon bikes can get a little squirrely on fast descents due to the geometry, the Serios is stable and confident at high speeds. Diamondback added a nice touch in the steerer compartment - a built in stop that prevents the aero fork from contacting the frame. While the newer Andean certainly has the eye-catching unique design and built in storage, if you're looking for a more traditional design with the credentials to light up a Time Trial, the Serios might be the trick!
Master Mechanic’s Notes
