Hi
Can anyone tell me where i can buy high quality sealed bearings for my integrated headset?
I need 41.8 x 6.5 x 30 (IS42) and can only seem to find cheap sets on offer.
Any advice would be appreciated.

    Contact the distributor of the headset in question to see if they have any higher end offerings.

    Hi
    That'll be Cane Creek and the only option i can find online is the cheap 'rust before your eyes' version.
    There is a choice of about 3 headsets that i can replace it with and they are all standard steel casings.

    Yep, the bearings are 41.8 x 6.5 for 1/1/8 steerer.
    They are Campy type drop in 45 degree.
    I can get the same bearings, but don't want to be replacing them again in 6 months time!

    IS42 headset/bearings are easy to buy just try a search. (as I said before).

    Thanks for your reply Nick,
    I have spent the past week searching the web only to find limited options on replacement bearings/headsets.
    As a last resort I thought i would try this forum in the hope that someone may know of some obscure site that sells decent bearings.
    I guess i will keep on searching.

    Columbus® Type Headset (SHIS term: IS42)

    The Columbus type headset uses a cartridge bearing holding-cup that is pressed into the frame. The frame has no special seat machined inside the headtube. The frame head tube has an outside diameter of 45mm and a machined inside diameter of approximately 39.9mm. A cup of 45mm outside diameter is pressed into the frame. The cartridge bearings sit above and below the frame in these cups. The bearings are nominally 41.5mm outside diameter and are a slip-fit into the cups. The bearing seat of the cups is 36 degrees. This headset allows the "image" of an integrated system by matching the headtube diameter with the cup outside diameter. The Columbus®-type headsets are not interchangeable with other types. Cups are typically painted with the frame, which assists to hide their appearance on the bike. Adjustment is similar to threadless headsets.

    Columbus® offers this system to frame builders with steel headtube inserts. These inserts are welded into the frame and are then effectively similar to the integrated system described above. The insert system is also in the 36-degree angular frame contact.
