What are some roadie frames that reflect triathlon geometry?
Quote | Reply
I've tried researching this and have failed. What are some of the road bikes and mimic triathlon frame geometry? Thank you in advance!

Reason? (Assuming you mean tri/tt vs road geometry.)

You assume correctly! I like the set up of a tri/Tt bike but need the handling of a roadie.

That makes no sense. The reason a road bike handles better is because of the geometry.

Otherwise, just slap some classic road bars on your steep angle TT bike and have at it!

but, but, but...they handle differently because of their different geometries... If you want better cornering/handling then you need a road bike, or to learn how to corner.

The geometry difference is only part of the problem; and maybe the more minor part of the handling problem. The other part of the problem is position. In particular, the very forward position, which puts too much weight on the front wheel. Having too much weight too far forward makes any bike handle poorly.

You can verify this. Take a road bike that handles well. Get a forward position seatpost, and get the nose of the saddle inline with, or in front of, the bottom bracket. The nice handling is gone. Try riding no hands; but only if you are prepared to crash. Or, do the opposite. Take your tri-bike, and put the seat as far back as it goes. You'll find it handles better.

I ride a Cervelo P3, and a S1. They handle almost identically. I'm comfortable cornering/descending on either. But the positions are nearly identical. I ride with the seat as far back as it will go on both bikes, but that leaves the P3 with the saddle about 1.5" farther forward, but still well behind the bottom bracket.

You won't find a road bike built around a triathlon geometry (76*+ seat tube, slack headtube). The reason (as mentioned) is that it would be a very poor handling road bike.

The best thing to look for would be a road bike with significant fore-aft adjustability of the saddle mount.

I ride a TT frame built as aboard bike. I can't say it handles poorly or all that great. I mean I ride it, it takes corners ( Crits and decents ). It's not like it's going to cause you to crash or drop people with your cornering skills. It is what it is.

Do you think the reason a road bike would handle poorly with a forward post is due having to have a crazy long stem to keep the same reach?
Alexi Grewal used to ride a custom Serotta with a 78 degree seat tube angle and claim all kinds of benefits.(I know the dude was nuts, but he also could make a bike very fast)

What I am suggesting is that a custom road bike with the proper geometry to accommodate a forward position might handle ok. Hard to say without riding one.

No. I think the handling is going to be poor with either a short or long stem. It is the weight on the front wheel that makes the handling poor. The weight is moved forward as the seat moves forward. I've done this both with road bikes (moving the seat far forward), and with TT bikes (moving the seat back). In both cases, even with the different bike geometries, the predominant factor in determining the handling is the position.

At least that is my experience.

What about less drop(taller head tube) and a top tube long enough so the stem is normal? I would think that would result in not that much more weight than normal on the front end?

I'd agree on the longer top tube, mainly because that shifts more weight back to the rear wheel. But that also lengthens the wheel base, so the handling will slow down, and there are limits (UCI) for the distance from the bottom bracket to front wheel hub (front center) is 65cm. Search for "front center" and I think you'll find some good prior discussion on this. I think Dan wrote a front page article at one point regarding handling and front center.
