Stem adapter

How do you like the VO Threadless adapter? I've been considering going that direction with one of my projects but have heard very mixed reviews.

I love the V-O adapters...

I have them on three of my bikes. They are less flexy than one-piece quill stems, but have the advantage of quill stems in height adjustability. They also have the advantages of threadless stems in being able to easily change the stem reach and rise angle, and change handlebars.

My $.02.

I thought I was crazy

putting a Specialties TA crank on mine lol. Nicely done!

I've been told I'm crazy..

I spent an obscene amount of money on this project, but it's turned out to be everything I had hoped for. Yours looks nice, too!

Did you re-space the drops

Did you re-space the drops using Sheldon Brown's 2x4 and stool method or have it done at a shop?

On another subject I've admired your Paramounts for a long time, just picked up a 68 last week.

Yes.

I coldset the rear triangle without a hitch per Sheldon's article. I did that before painting.

Thanks for the comment on the Paramounts. Enjoy yours.

One last upgrade to make ...

So if you threw away the frame and put, say, a carbon-steel raleigh grand prix frame on that bike, wouldn't it get another 2 lbs lighter ?? And if you put a 531 frame and fork on that bike, wouldn't it drop a total of 4 lbs, down to about 22.4 lbs ??

Frameset weights

I could easily have chosen a lighter frame and shaved four pounds off of the total weight, but that's not what I was after. I wanted a bulletproof bike that would stand up to lots of punishment. This straight gauge 4130 chromoly fillet brazed frame will take whatever I can dish out without a whimper. The frame weighs 7.05 pounds and the fork weighs 1.96 pounds (nine pounds total). A similar sized (61cm) double butted 531 frame and fork (my '72 Paramount) weigh about seven pounds for a saving of two pounds. My 61cm 953 frame with 531 fork weighs five pounds (four pounds less than this Super Sport frameset).

For an interesting article on these frames, see http://www.sheldonbrown.com/schwinn-braze.html ...

stem

The way that threadless stem adapter is installed scares me. My friend installed one of those too high and broke the fork inside the headtube going downhill. He got a plate in his shoulder.

Stem should be fine

Thanks for the comment. The stem adapter is inserted into the steerer tube well below the 2-1/2" minimum insertion line. Right now, the stem height and seatpost height are approximate since I'm waiting on a backordered FD cable cable guide before I can ride the bike and fine tune saddle and handlebar positions. If I decide I need to have more adapter in the steerer tube for safety, I can get a 6-degree stem and flip it to give me the same bar height.

Don't mess with a classic...

unless you do it like this. Cheers!
