Hi there,

I think I need to replace the headset (integrated) on my 2007 felt z 65 ( http://www.bikepedia.com/quickbike/Bike ... &Type=bike ) and was wondering if there is a standard integrated headset that will fit most frames? Or are they frame-specific?

Might this fit?

Thanks muchly

    There are three standards for Integrated headsets - Cane Creek, Campagnolo and TH.
    The first two are by far the most common.

    assuming your steerer tube is 1-18" dia then the most obvious difference between them is the size of the bearings. CC use 41.0mm dia bearings, Campag use 41.8mm dia and TH use 41.5mm.

    Second difference between them is the internal and external angles (chamfers, for want of a better word). CC use 36° int and 45° ext., Campag use 45° for both and TH use 36° for both.

    None of these are interchangeable. So you need to replace the bearings for ones of the exact same type. If you don't know which you need, the easiest way is to take the bearings out of the frame and off the fork crown. They are a loose fit. The size and type is laser etched onto the outer race of the bearing. If for some reason it is illegible, then you'll have to measure them. When you know what size they are, you'll know what standard they are. Purchase as appropriate.

    Note that you don't have to buy a new complete headset. You only need new bearings and they are freely available. Take a look here:

    If in doubt, give Dotbike a call or email, and they will help you.

    wow very comprehensive post indeed proto- thanks! :wink:

    However, my bike resides on the other side of the country, and google isnt helping me, so Im not sure what type of headset Ive got..

    I believe I saw cane creek written somewhere when I took it apart tho..

    The way Ive interpreted what uve said, all cane creek headsets should be the same (eg. 41.0mm, 36int, 45ext?), so
    if I buy any cane creek type, it should fit?

    Thanks again!
