Got my spacers. They aren't the tilt blocks, they're the armrests blocks. And they didn't include the washers, so can't even really use those. Was a total waste of $25, so that's annoying.
I couldn't figure out how any type of angled spacer would work, but now I see the proper tilt block adapters have a plate that slots in that the bolts thread to, and then you attach to the bare bar? Seems pretty cool. I guess I'll abandon it for now since I don't want to spend another 130 bucks for the proper tilt block from aerocoach. May reconsider this summer.
Stem should be here today at least, so hopefully I can get it all adjusted and dialed in a bit better.
