I'm building a on the Kaffenback and in it's head tube there is two little bosses on either side to screw in a barrel adjuster.

Can someone post a link to ones that'll fit.

Thanks.

I lifted mine from a set of adjuster bosses of the type that bolt onto the brazed on bosses on road bikes. they are either Campag, Shimano or some old Weinmann brake ones. Helpful hey? Importantly get short ones as the braze-ons are a bit too far forward and snag brake cables if you are not careful. I started with springs behind them but they would go in far enough and snapped off. The shortened results are fine.
