I have just bought a 2010 Giant XTC 29er frame with no headset.
I already have some Reba’s but the steerer is 1.1/8 can I make the two work with the frames tapered steerer?

Thanks in advance

You should be able to use your existing fork , you just need the right headset . Take a look at the hope pic and mix ones .

Check it out, headsets are murder at times!!!

Hope and FSA have similar tools, measure up the steerer tube if you struggle to find your bike and use hopes website to work out exactly what you want.

Hope’s hs136 crown race converter lets you run a 1-1/8th fork in any tapered headset/headtube.
