A2J Shows 10.6lb Di2 Road Bike w/ 640g Frame, Including Hardware!
It’s been pretty much one year exactly since we’d heard from A2J, the Swedish company that’s building “custom stock” carbon fiber road bikes at ridiculously light weights. Thankfully they pulled me from my dazed wonder in the halls of Eurobike to point out their latest version of the Rolo and a custom build that came in at just 10lb 9oz.
The Rolo frame uses stock geometry and sizing with full custom layups, so you get it built for your weight and riding style. The sizing and geo are stock because it’s a monocoque build. Five sizes from 48 to 60 with a pretty linear stack and reach progression.
One of the more amazing things about the weight on this bike is that it’s Di2…meaning there’s a gram hogging battery in there somewhere. Where, you ask?
They’ve hidden a soft air gun battery in the seatpost.
Headtube shape is pretty aero, not hurt by the fact that they’re running a 1-1/8″ straight steerer.
The underside of the headtube transitions nicely from the aero shape to the downtube.
Only selling fully built bikes, they spec three basic kits ranging from €15,000 to €20,000. They said it typically takes about 60 hours to build a frame, more for the really light ones because they weigh each piece of carbon to ensure it’s to spec.
10lb 9oz on our scale, which equals 4.78kg.
