Belray H1R

I've used belay since the 90s after busting a pistion on a sweet smelling oil I won't mention. It has never let me down even when I've went a little long on top end rebuild. Everything always looks good and clean. Powervalves and all. It's expensive but worth the extra money for peace of mind for me.
