Tapered headtube / straight forks?

Stubat

Hi,

I've been searching the forum, google etc and am struggling to find a definitive answer.

I currently have a tapered headtube on a boardman team r with carbon forks. The forks have a tapered steerer, 1.5" bottom, 1 1/8" at the top.

I want to change to a pair of rock shox forks which have a straight 1 1/8 steerer.

Can i just change the crown race for something like this

Or do i need to fit the bottom half of 1.5 headset as well? I cant be the only person to have this trouble

Any help, very gratefully received!!!

You need a 1.5 to 1.25 reducer at the bottom.

You may need one of these.

Yep your right there! my mistake but im sure you can mix and match the Hope headsets.
Maybe it's this one you need?http://www.hopetech.com/page.aspx?itemID=SPG188

You can but Hope are silly expensive.
Cane Creek are mix and match and much cheaper, and I think Superstar do the same.

1.5 to 1.125 is what he needs, just for the record. 1.25 is 1 1/4 inch (like the new standard from Giant), 1.125 is 1 1/8.

Good point, my mistake - bit of brain fade.
Was on my phone and couldn't work out 1 1/8" in predictive text.
