How much steering tube do I need on my fork?

I'm thinking of buying a fork off of eBay and there's one in particular I'm looking at that has 195mm of steering tube left. How do I know if this is enough for my setup. From what two points on my bike should I measure to determine how much I need without removing my fork?

How much steerer tube is available with a brand new fork and how much gets typically cut?

Excellent question, I've been wondering about that too.

well the headtube length on a hardrock 19" is 120mm. i'm planning on getting a 180mm steer tube fork, so that leaves about 6cm for headset, spacers, and stem.

my fork had about 9 inches of steerer, i cut off about and inch and 3/4"... just measure the steerer on your fork now, and go by that.

Measure from the bottom of your bottom headset cup to the top of your stem clamp. Anything within a 1/4" from the stem cap is good, any shorter and it will be too short and not enough of your stem will clamp the steerer.

Thanks - so looking at the two pictures below, I really need only between 180 and 185mm?

Yes thats all you need. You could also take out your spacers if need to gain even more room and just get a very thin one.
