Fair enough, I’m not a huge fan of the design in general, but I think the silver and drillium could work in this slightly neo-retro application. I’m not sure I agree that the black levers do a better job of hiding the shape since they draw additional attention due to the colour mismatch. If it was my bike I’d probably keep the black ones as well, rather than buying another pair and having the black ones end up in the spare parts drawer.
P.s. I absolutely adore that anniversary frame, it’s such a great and unique combination of old and new elements!
