Head Tube size

[dougmcdoug]

Hey Guys
I have a new frame that i'm thinking of building up, but the headtube diameter looks small. What's the standard internal diameter to fit a headset in for a 1 1/8 fork.

Cheers Doug

anybody know what the size needs to be to put a headset in?

Take it to your local bike shop... they'll be able to let you know what size headset you need. If it looks small it could be 1".
