Closeup Look at A2J Frame R Ultralight Carbon Road Bike
While the concept boasted some custom Di2 shifting integrated into the bike as an option, the show model was decked out with a traditional mechanical shifting setup from Campagnolo with THM cranks. In person, it’s a darn good looking frame, but we couldn’t lift it or weigh it thanks to some big fat uncooperative zip ties. They’re sticking to their 850g maximum frame weight, and that figure includes the headset, seat clamp, front derailleur mount and rear hanger. More pics and details after the break…
Carbon, carbon everywhere…from the seatpost collar to the brakes, almost everything on the bike is carbon fiber.
Most of the frame has woven fibers, but the seatstays get UD carbon tubes with woven patches reinforcing the brake bridge and dropouts.
The headset is a straight 1-1/8″ to keep things slim and light, yet the bike boasts a very high stiffness to weight ratio. It also helps keep the front end more slippery to the air, which is also a goal for A2J. They are doing wind tunnel testing with this bike as they near production.
Don’t worry, that rider weight limit equals 330lbs. Pricing? It’s a lot.
