So far, so good! I got the non-drive side of the bottom bracket sealed cassette free, but had to drag the frame over to Green Lizard to get help with the drive side, as my bracket tool from Amazon is an ill-fitting piece of crap.
I cut up an inner tube and hot glued three strips across the top of the motor, where it touches the downtube.
Whatever shortcomings the Gravity DeadEye frame has, clearance for the BBSHD is not among them. Slid in like it was going home, and required no spacers for a near-perfect fit. So after a quick dry fit I got to work on the support ring and locking nut (using plenty of BLUE, not RED, Locktite to honor Thomas Jaszewski).
Snugged everything up as tight as I could, then added the aluminum cover and brake side pedal.
Stock Bafang 46t chainring, and then another pedal.
Check out the perfect clearance! Almost as if I'd planned this all out! No idea whose toes those are. Intruder, no doubt.
That's not the rear wheel I'll ultimately be using, but the chain line seems pretty okay. The Sturmey Archer RS-RK3 should put the sprocket closer to the dropout, and improve the line, but it already looks pretty decent.
So now all there is to do is everything else! Off to Lowe's for some zip ties (could have sworn I had some around here...), then the Personal Hell of routing all the cables so it doesn't look like an Italian electrician's nightmare.
Updates as we progress, and thanks for reading!
