I'm tossing around the idea of buying a cheap TT bike on Ebay. I'm totally not serious about this stuff, i do 3-4 TTs and about 1 tri per year. I'm just so curious about how an aero set up would affect my times. I'm afraid of clip ons.

Anyhow, which direction would one want to err...too small or too large...when it comes to a TT bike? I'm currently riding a 51 Ghisallo road bike w/ a 52.5 top tube. I am slightly too stretched out, i made it fit w/ a short stem, girl-specific handlebar.

So for a tt bike, would conventional wisdom say go smaller or bigger if not this precise size? I'm 5'2" , long legged but short torso. Thanks!

You don't need to think of buying a TT bike until you can average 23-24mph in a 20K.

Unless you spend a lot of time in the forward position that a TT bike has, you might even be slower on the new bike ( you'll be using different muscles)

Most of the cheaper TT/Tri bikes come with clip-on aero bars from what I've seen, and you need to spend some money on the integrated TT bars. I don't have a TT bike, but see most people going with something slightly smaller than their road bike.

maybe I'm confused by the terminology. What I want is a bar with shifters where my hands will be. Isn't that integrated? What I don't want is something that has to be bolted on to my handlebar, and thus subject to moving around while I'm riding if I screw up the installation.

yes, you're right re terminology - I say get a TT rig. They are fun and fast. As for sizing, most people go down in size. Some pros go radically smaller. Dave Zabriske rides a 58 road frame and a 54 TT frame, mainly to get as low as possible. Since it sounds like your road bike is a bit long, your sound like you should go smaller as well (a 1-2 cm shorter top tube). The slowtwitch links are good re sizing and fit. A frame people have been buying (including me) is at this link. Frame for about $500 plus shipping. It's pretty inexpensive to build up a TT by scouring ebay for parts (new or used).
