Our featured sponsor this week is once again Full Speed Ahead! FSA (www.fullspeedahead.com) just donated many of the major remaining components we will need for the drivetrain/bicycle frame, including cranksets, stem, seatpost, and headset bearings. Theirs are among the lightest components available, and with weight being such an important factor on the Atlas, we’re happy to have the best. Our heartfelt thanks to the team at Full Speed Ahead!
Two cranksets are necessary for the Atlas, as we wind the drive line from the rotors onto spools on both sides of the bottom bracket. We also need a longer spindle length, in order to accommodate the drive line spools on both sides between the crank arms and the bicycle frame members. This meant we had to go with a custom solution here, and nothing off-the-shelf could be quite satisfactory. As you can see, we’ve taken the right-side crank (with spider) from each crankset, and machined each spindle to make a joint in the middle.
