Headset Question
I am rebuilding my Trek 7500 frame with mostly road components. It now has flat bars, a quill stem, and aluminum fork. I want to replace these with a carbon fork, road bars, and some kind of stem/headset combo. What are my options for headsets and stems if I no longer want to use a quill stem? Thanks for any advice.

pretty much infinite as long as it's the same size steerer. Even more if you want to use adapeters.

Well, there's the quill-type and the threadless-type, so you'll need a threadless headset and a threadless stem. There are tons of them out there, so you have plenty to choose from. They come in either 1" or 1 1/8" sizes, so be sure you get the right one.

Thanks for the responses. I have never disassembled this bike's headset so I wasn't sure if I was stuck with the quill stem. Guess I just need to tear it apart and go for it.

Im curious as to what other components yer gonna switch out. If you want to keep the v-brake up front you need a fork with canti bosses. Don't believe that frame will accept a road brake in back. You'll need a Travel Agent in place of the regular noodle to use road brake levers with v-brakes.

Another issue might be the front derailleur's incompatibility with Shimano STI road levers. |
Carbon forks are vaguely lighter than aluminum, but both are lots of fun, because of CATASTROPHIC FAILURE. Yippee! And when you pluck it, it goes "clunk" instead of "pink." But I suppose that this makes sense, given that you'll be surely racing criteriums on this bike.

Jeez,
Noodles, Cantis, Travel Agents, Crown Race, Pink and Clunk. Now I am confused. For more background: The crank on this bike is trashed and is the wrong length for me. The cables, shifters, brake levers, bottom bracket, and rear hub have also seen better days. I appreciate the thoughts on the brakes, I am fine with the existing brakes but want to install STI. As near as I can figure, I am going to have to use an MTB crank and bottom bracket to fit this frame. I want to get rid of the adjustable quill stem and flat bars. The existing derailers are okay but I plan on using a road cassette. I already have a new Mavic wheelset with 105 hubs. I happen to like the feel of the carbon fork on my Lemond so will install one on this bike as well. Thanks again for your thoughts. |

Juicemouse,
I am on the receive mode now and will try to follow through on your suggestions. I did check out the spacing on the frame before I bought the wheels and they work fine (they have about 1000 miles on them). Your first comment is appropriate. I also keep looking at new bikes rather than buying all of the stuff for this one. I am sure that I will have a lot more questions as this progresses. |
I did part of the conversion you describe on an Al frame rigid early '90s Trek MTB.
I kept the stock threaded fork and headset and fitted drop bars, a new quill stem and an 8-speed STI rear shifter. I had to use a barcon for the front shifting to allow for the MTB derailleur /Road shifter incompatibility noted above. I also converted the stock rear hub from 7-speed to 8-speed and respaced the wheel to compensate for the wider freehub body. I kept the original 26" wheels. What made this practical was that I had a parts box full of unused items so the only purchases I had to make were a set of low cost 25.4 mm drop bars, a cheap 1-1/8" quill stem and 1.25" slick tires. If I had to buy all of the replacement parts, I never would have considered the project. |

I do stuff like this because I like building up something from scratch, something that is perfectly tailored to the way I use it, something like no one else's bike. I enjoy the process almost as much as I like riding it.

Second, I never rode the bike in real off-road conditions and don't like flat bars for road riding so this was a way to convert it to something useful. I also fitted the bike with fenders and a rack and it became a rain/beater/errand bike so it gets some use.
Great way to learn about bikes, too. ;) |
