For those who need info on their integrated headset, I spent all day today traipsing around every shop in the area looking for help getting an integrated headset. In theory these are so user-servicable that every shop should carry stocks. In practice it's a little different:
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. 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. If you install the wrong size, you'll destroy not only the cups but the entire frame, as the cups are usually made of aluminium, which is soft and deforms easily.
Cyclesurgery in East aldgate have a FSA tool to measure the shape and size of your integrated cups. It's also worth noting that evans / cyclesurgery carry NO stock of any integrated headsets at all, even though they all had both super record 11 speed and DA 7900 groupsets in stock.
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:
