I just switched out my OEM top cap for a carbon cap & new bolt. I bought. 3g difference.
I ended up going with the Bontrager's carbon cap that I had stored and it was a much nicer transition. I have a 1mm (didn't register on my scale) spacer on top of the cap where the old spacer was 2.5mm Al (3g). While I was tinkering, I removed the stem and replaced my 25mm conical spacer with a 5mm spacer, re-installed the stem and WOW. I love it. I love how it places me on the bike. I love the feel. I can't wait to land a 5-10mm conical spacer that'll be appropriate for my set-up. That is priority 1. I also saw that my Crane Creek 25mm top cover is a whopping 30g. I could lose an easy 20g when I drop my stem this week. Just found out I have a Cane Creek IS24 Headset. Some info for anyone interested in working on their CAAD9:

The internal angle becomes almost irrelevant as long as you use the supplied compression ring and crown race of the particular headset. For example, Cane Creek IS-2i is 45 x 45 x 42mm and Cane Creek IS-3i is 36 x 45 x 42mm. Both are compatible and adhere to the Campy standard. The only reason Cane Creek made the switch to IS-3i is that it's simpler for them to make one type of crown race and compression ring to fit both IS and Campy standards. The only headsets made by Cane Creek are the ones you can purchase in a box. Namely, IS-2i, IS-3i, IS-8i, IS-2, IS-3, IS-6, IS-8, IS-110 and so on. There are many outfits in the far east who supply OEM headsets based on the Integrated design. The thing you call patent is just for the cover. The IS24 you have is a Campy copy made by Tange. It's still a 45 x 45 x 42mm bearing and assembly. |

I'm planning to slam my stem.
Would love to see any pics of slammed stems here and know the sizes & brands of your conical spacers. I'm thinking about going with a 15-10mm spacer under the stem. I already have a flush carbon top cap. Thanks. :thumbup: http://i1108.photobucket.com/albums/...4_1345-5-1.jpg |

Here's my contribution. Might eventually get a -25 stem as effective HT (with headset stack) is 16cm...

where did you find the low-rise top caps?
the conical spacer on my S2 is aluminum and easily 15mm tall...looking to swap it out I haven't found what I'm looking for yet. I just used one of my standard spacers to get an deal of how low I could go and to get a feel for it. I've located a few 10mm conical spacers, but I don't know if they will fit my CAAD9. When I get to my LBS tomorrow (which is a Cannondale dealer), I'm going to see if they have any Slice top covers. They are supposed to be a perfect fit and come in a 10mm size. If that doesn't work, I'll gamble with whatever I could find. |

you are giving this too much thought. I have 2 bikes and with both I went out to the shed on impulse and hacksawed the spare off and took them right down. Never regretted it. Just do it. If your neck aches just buy a new bike :-)
I just don't want to take a chance with making a mistake with my fork. It would be a $400. mistake. |

oh, and i did get the -25 stem after all https://lh6.googleusercontent.com/-8...0/IMG_0455.jpg |
This might be the solution if I can't find a 5-10mm conical spacer:
A Veloflyte Headset Dust Cover + one of my carbon spacers (1-5mm or 2-5mm) on top of it. I was concerned about the dust cover being a weak point, but it comes with metal shims so support it underneath.

I'm almost tempted to make my bike into the most un-slammed bike you can just to watch people's heads explode.

true that, but i got the frame for a very very good price. alas...
actually, last year they had a cooper BB30 frame in a racier geometry (11.5cm HT). With a HS with a shorter stack, I would have left it as with the -17 as opposed to getting the -25 |

Just changed my headset out for lower stack model and gained about 3cm of drop. This will go a long way in making my best riding bike fit more like my best fitting bike.

I've also switched the bolts (3g OEM for 2g bolt) and starnuts will be exchanged tomorrow "if" the one I have now is actually lighter than OEM). With original 2.5mm spacer and top cap (I don't know if you can see it in the pictures, but in person, the more tapered Bonty cap and 1mm spacer make a HUGE difference, not to mention that the carbon looks a lot nice than the matte black Al cap): http://i1108.photobucket.com/albums/...4_1345-5-1.jpg With 1mm spacer & Bonty top cap. I'm going to file down the hard edge a bit to soften it up in order to taper it to meet the cap: http://i1108.photobucket.com/albums/...D9/Stem001.jpg http://i1108.photobucket.com/albums/...D9/Stem004.jpg |

does nobody know where to get an aftermarket conical spacer / dust cap? mine is the same as sosojeffcc's - but pros seem to have much smaller ones.

I did that with Cane Creek and they gave me an answer right away. You may have to buy a complete headset to get an OEM conical spacer sized the way you want. How low do you want to go? 5? 10? 15mm? Also, check that Cervelo link I posted for you. 1. BF 2. WW 3. Cervelo |
Entertainment!
Damn this is fun!!

Cane Creek headset with the short top cap + 5mm spacer. Soon to be 2.5mm spacer. None on top, but I have the special Cannondale top cap that extends down into the steerer tube to reinforce the clamping area.

http://i110.photobucket.com/albums/n...dsetspacer.jpg It was only $10. more than just the top cover alone (and $15. less than what I could've gotten it for). It's pretty much identical to your top cover, but I went with a tapored 2.5 spacer to meet the bottom of my Bontrager stem better which tapers at both the top and bottom of the stem. I'm ditching the Cane Creek top cap which is flat (I thought I was going to go with that look), and am going to go with the Bonty carbon cap without the 1mm spacer for a nice finished look. The Bonty cap is being countersunk a little to meet the profile of the stem perfectly. The 9mm top cover alone just didn't look right. It looked unfinished with my stem. In the end, it's a 13.5mm drop from stock with the 11.5 height. Probably -20g. http://i1108.photobucket.com/albums/...D9/Stem001.jpg Notice the stem how it tapers in. |
That stem still isn't slammed.

Oops...when I posted earlier I actually meant the conical spacer, not the top cap.
Regarding the top spacers that people are using. How do you guys manage to use any smaller than 5mm? I used a 5mm top spacer just to make sure there was enough steerer sticking out past the stem for the headset to compress. Any smaller of a spacer I felt didn't give enough of a margin. |

Going any lower than that, I'd get nervous. I don't want my stem sitting right on top of my bearings. 9mm with that shaped spacer didn't look right IMO on my bike. Again, I was very limited by the OEM headset I was using. If I were to do this on a more expensive bike, I'd use the Campy Record headset. http://www.bikepedia.com/Images/imag...9.jpg&f=Hawley I experimented with different sizes before I decided on 9mm. Didnt like anything lower. Even though I ended up with 11.5mm (9mm for the top cover + 2.5mm for the tapered above it), it's very proportional to the rest of the set-up. There was a balance I was looking for...low, but not too low. |
