:oops: Just got a ribble winter training frame, with ribble's Alpina hidden aheadset. Cups and cones I understood; but can't figure out what order to put bearings, shims etc. in. and no idiot picture to help! Any clues/site I might visit?

    not sure if this will help or not - but the specialized website gives downloads for their "frame instructions" - i.e. assembly instructions for putting their s-works framesets together - if the parts in this look familiar then perhaps you will be able to assemble your ribble from this diagram? - worth a go
    anyway - click here:

    http://www.specialized.com/bc/SBCGlobal ... =downloads

    and in the bottom right of the page click on the link for "07 tarmac SL roubaix ruby frame" - it will download and open a PDF with the exploded view of the integrated headset.

    hope this helps!

    Starting from the forks: crown race, lower bearing, frame, upper bearing, top race cover*, split collet*, spacers, stem, star nut / wedge and top cap. Sometimes the split collet and top race covers go the other way round - depends how the fit of the cover on the fork steerer, if it's a tight, sliding fit then the split collet goes before. If sealed bearings, they face opposite directions - on the lower the bearing seal is downwards and on the upper, it faces up. There's a chamfer on the bore of the bearing that engages with the crown race too. If it feels sloppy or there's a big gap somewhere then it's probably not right...
    Make mine an Italian, with Campagnolo on the side..
