Replacement headset compatibility...Help please!!

Hi,
I need a new headset but haven't got a clue what kind will fit my head tube.
The existing headset that came fitted to the bike when I bought it is a VP A41AC semi-integrated aheadset. I cannot find these for sale anywhere but would much rather get something better anyway.

Here are some more details:
Frame: Bianchi SL3 Alu/carbon

Existing headset:http://www.vpcomponents.com/headset.asp?pcat=&pcat2=12&nowPage=2&pagesize=5#
VP-A41AC, 1 1/8, Diameter: 28.6/44/30, stack height 5.5 + 3 = 8.5 (don't know what the diameter and stack height figures refer to!)

Anybody got any recommendations as to what I could replace this with? The bloke in the LBS said I need "the same headset" but surely my choice cannot be limited to one specific headset!

Thanks in advance

Marc

    You're quite right, the guy in the LBS was talking poo. There are a few semi-integrated ones available but you have to be careful as they can differ in the length of the portion pressed into the frame. The safest way is to knock yours out and measure the depth of the recesses in the frame.

    I got mine from here. Arrived very quickly, very helpful staff:-

    Actually, the LBS guy had a point. It's often best, and easiest, to replace a headset with the exact same model. This deals with all of the incompatibility issues. So although you could try and find a compatible headset, it would be easier to buy another VP. VP headsets are usually fine. I've been using one for years. Stronglight headsets are excellent though.

    FSA do a suitable headset (although I suspect that they all come out of the same factory, irrespective of brand)

    Have a look the Windwave/FSA products

    and specifically at the various Orbit Z types shown.

    Alternatively have a look at Cane Creek here

    Neil at www.dotbike.com would get either one for you, give him a call.


    If you can struggle through the TH Industries site, you might find it interesting!!

  • Thanks for the replies guys.
    Our boiler has just packed in so i've got a bit more on my plate than doing up my bike for a while.
    At least I now know I have some options.
    Thanks again.

    Google turned up this on ebay and, if you believe it, it has the specs that you need to order an alternative replacement :

    marc,
    I have a downloaded copy of the FSA headset book but it is a huge PDF. The FSA site doesn't appear to have this now but the dimensions of their headsets are there. 28.6 is the diameter and 44/30 the bearing angles. Thanks Proto!

  • HI Neil, Would it be possible for you to send me the PDF of the FSA headsets. It does not look like it is available anymore on the website. I have sent FSA an email asking if it will be available again but have had no reply.
    Cheers,
    Stu.
