Mmm, looking at my collection a bit more, it seems like you're right. I misremembered the measurements on my Miyata 710. It's less non-square than the larger Fuji America.

That setup looks worse than it may be because of the type of stem you have - if you get a 1"-to-1-1/8"converter and mount a more modern stem (pictured) it won't seem as severe and will have greater strength/safety than an old 22.2 quill jacked up that high... In the days of old I saw a stems like that break when the guy had it out of the frame that high - basically the internal expander bolt will be the only thing saving your bacon at that point, with basically no steering left.

I might take my chances. It's a heavy part in an ancient product line made specifically for ridiculous height by a reputable manufacturer, and I'm not even close to its specified limits.

If durability is a concern, I'd probably get a quill with a rising extension rather than a threadless adapter. Should improve strength for the same reasons and would keep the build simple.

That's what I did with my Paramount. This particular converter is at maxiomum insertion.

Most that use that stem aren't racing on it. They are low-key touring bikes. I wouldn't recommend you do a standing start with it. You are gonna get too much leverage going against where it binds inside of the head tube (not sure of the proper term). Maybe look into getting modern equipment.

That shouldn't be an issue. Leverage is proportional to the distance between the force application point and the lever's rotating axis, which is actually pretty tiny in my case. In many stock setups (including the stem that came with the bike) the wedge is substantially above the primary grip, in this case it's slightly below. I should have almost no leverage at all against the wedge when riding in the drops.

edit:

Here's the current stem setup.



And here's what the bike came with.



(Although I suppose the force is more perpendicular in the new case, probably offsetting the benefit of a shorter lever.)

My new custom Duratec. I'm thinking of calling it Goliath (those aren't 650c wheels)

Given Duratec is custom, surprised you didn't build it bigger?

It's as big/long as they can/will go. We wanted the TT 15mm longer, but their jig wouldn't take it so we had to opt for steepening up the seat tube and a longer stem to achieve the same fit

By the way you guys are right, I'm dumb.

I rotated the fit forward. Saddle position is extremely close to not being UCI legal, heheh... but it seems to work, and is much more track-bike-ish than before.

Actually I did, but this thread is co-titled "training". My apologies if my bars are inappropriate for this forum area.

Not inappropriate at all. Bullhorn bars are the pursuit bars of ~25 years ago. Recently back in fashion with the fixie set.

Classy frame, personally I'm much rather see it looking something like this. But I am a bit of a traditionalist.

Nothing wrong with the bike at all. Just realize that if you're racing on the track (and in some places training in groups), you will only be allowed to ride the track with those bars if it's a Time Trial. Group racing (and training at most tracks) requires that you have drop bars mounted.

Scotti, technically, those bars are legal for time trials only. Not group races or even group warmup. Basically, anywhere you will see modern aero bars.

Well the timing is about right as my DR is about 24 years old.

Handbrakes! Never knew they were used back then.

I only wish I could ever get back into shape to be concerned about those guidelines. The only track near me is the one pictured (Kissena in Queens NY). On Sunday mornings when I get to ride I'm usually the only one there. They do run events on certain weeknights, but I'd have to take a day off from work to get there in time ... and then embarrass myself . Weeknights, I ride VERY cautiously on car free loops in parks. HAd the bike customed sized for me years ago and NOTHING feels as good.

Anyway, I appreciate the advice. Jealous of you guys (gals)!

Naturally, I think that's gorgeous! I like the black chain. Is that a record? Finding them nowadays is nearly impossible and $$$.

The Visp in racing trim

Threw on my old racing wheels, so I can use it tomorrow at my state masters track championship. It's still pretty heavy, but I'm going mainly to show support for the promoter who is including older age groups. Also, the junior and youth championships are on a separate date, so I don't have to worry about some squirrely kid taking me out while I warm up on the track. I've geared it pretty low (47 x 15) for the standing 500m TT so I don't blow out my aging knees. I haven't ridden the track in three years, so hopefully I'll remember how to turn left.
