My brand spankin' new 52cm CAAD9 has a 25mm carbon cone headset cap. This is excessive stack in a stock setup, in my opinion, and both my local dealer and cannondale tech support have given me the run around in trying to find a compatible lower profile option. Cannondale even went so far as to suggest that I shouldn't even try to use a lower stack setup as the geometry would be impacted. (Lars @ Cannondale, this is baloney) This kind of support is mucking up what should have been an exciting experience!
Anyway, 25mm is about 8mm higher than I'd like. My LBS offered a canecreek IS3i top cap (maybe 2i?), but it didn't cover the bearing well enough and there was no rubber lip seal. The CAAD 9 upper headset bearings dont settle in flush with the top of the headtube, so any top cap has to extend down around the bearing a bit further than most aftermarket solutions. I think the canecreek IS comes with a 36x45 bearing which is why it didn't adequately cover the 45x45 bearing that comes stock. I really like the weather protection that the stock cap includes, and find it hard to believe there isn't a lower profile option available from Cannondale.
I did search the site, and found this thread : viewtopic.php?f=3&t=65615&hilit=cannondale+CAAD+headset&start=0
It provides a lot of answers, and shows that the headset used in my frame, confirmed by cannondale as the Tange IS24CLT-25, should have some other top-cap arrangements that fit like stock. Specifically the one at this link : http://www.tangeseiki.com/tangeseiki_ne ... 013293.gif
, has a 17mm cap option that would be nearly ideal! (Ideal would be a 15mm carbon cone spacer/top-cap, one-piece, as light as possible, with the weather protection of the stock setup.)
Does anyone know how to get a hold of a replacement top-cap such as this one from Tange? Are there any other options worth pursuing?
I know the CAAD9's are really popular on here, so I'm sure there have been, or will be others who have needed to lower their stack a bit below that ridiculous stock cone cap.
Thanks for any help or links people can throw down!
