Well, a padded envelope arrived this morning..... luvverly new black rear mech and chainring bolts.
Kronos - Got them from a guy called John McNulty - who was doing Kronos bolts bits - and is still doing them.
I'd not heard of them before - but I like what's arrived. Will get them fettled and get some photos up.
Thanks to Phil again for acting as postmaster - kudos fella -
