For starters; besides the handling, there's the issue of the bars usually employed on most TT courses not being UCI legal for mass start races.hestilowt said:why would i not want to use TT bike for a road race???
what if i got two sets of handlebars, one dropped, one aero???serenaslu said:For starters; besides the handling, there's the issue of the bars usually employed on most TT courses not being UCI legal for mass start races.
You normally will not have optimum geometry switching back and forth. The riding position is usually significantly different on a dedicated Tri/TT frame.hestilowt said:what if i got two sets of handlebars, one dropped, one aero???

I'll call you out on this one. My Tri bike is WAAAAYY more comfortable than my '01 GT.ed073 said:Too uncomfortable hours of racing.

I've ridden more bikes than I care to remember.
No way I could ride a TT frame for the length of a road race. If you can, good luck to you.

I think that alone should debunk the "uncomfortable TT bike" Does it take a little getting used to? Yes. But my buddy got off his new road geometry bike hurting as well. If you expect to hop on a TT bike after riding a road bike for a long time, the position IS gonna be different, and therefore hurt. But a new rider who doesnt have to adapt his old ways should be fine. Do they ride like a Lincoln Towncar? No, but mine is no more harsh than any other Alum frame/ carbon fork bike out there
ed073 said:set-up on a triathlon bike is different to that for road TT racing.
what are all the differences in the geometry??? the only thing i know of is the angle of the seat tube (i dont know if thats what its called but the vertical tube where the seat post goes into) on a tt bike is steeper than a road bike, but on all the bikes for my size it's only a degree or at most 2 off, would that make a difference???GEG said:
I would concur with both opinions. Moreover, the question definitely makes sense to me!
My $0.01:
Triathlon bikes seems to be set up for muscle "economy", necessary for the following running stage, even tho good Triathlon bikes are essentially TT machines. My guess is that geometry has a role on this, and if this is true, perhaps the subtle angle differences also lead to some degree of comfort. Triathlon athletes surely cannot setup their bars as low as possible because of the strain it would cause in the back. Straining the back would make the runnig phase an even greater challenge.
Drafting is not allowed on TTs and triathlon races. This is a major thing to take into account. In road racing, you can use slipstreaming as part of your strategy, and yet must find the best balance between speed, acceleration and handling (not to mention severe climbing, usually not found on TTs).
TTs bike are all about speed, not comfort or endurance - you give what you get and that's it. I know this is controversial, but I also dare say that a good TT machine would be heavier that it’s road racing counterpart. A TT bike takes aerodynamics more seriously than any other factor.
As for me, I would happily use a single aero frame for everything… of course, I compete for a good pitch of beer and not for $100,000 prizes!
great article, thanks very much!supergrill said:Here is a link that does a pretty good introductory job of explaining the basics to newbies as to why true TT/Tri bikes are great for aero-tuck postion solo runs and lousy at handling and general all-around use.
