Road Bike or Tri Bike ? - The Million Dollar Question

Ahh yessss... the tri bike vs. road bike quandary. Before you wannabe bikers even ask the road bike vs. tri bike question, you should have a couple sprint triathlons or duathlons under your belt ok?


" But the fact is that I wouldn't have won even a single Tour de France without the lesson of illness. What it teaches is this: pain is temporary. Quitting lasts forever. " Lance Armstrong


For your first couple of practice sessions, use whatever you have available to you. Ride your friend’s BMX, borrow a bike or buy a Php1,000 garage sale bike. Whatever it takes. You’re probably not going to win anyway, so you might as well try it out and see if it’s going to be something you’re going to enjoy.

When you make it to this point, it might then be the time to ask the question: tri bike or road bike? Which is which?

Give up?

There’s not one fit-all answer here. Every one/individual is different.

Take into consideration:

1. What are you trying to accomplish?
2. Do you plan to compete and/or train for triathlons on a continuing basis?
3. Have you been bitten by the bug, or are you still just getting your feet wet?
4. Are you primarily riding in an effort to train for multisport events, or do you plan to ride on a regular basis with your non-triathlete friends?
5. Pamporma lang?

We’ll get back to the above questions. First let’s take a quick look at standard road geometry and tri-bike geometry.

Road bikes

Road bikes are made to handle well in a wide variety of circumstances including climbing, cornering, or riding in packs of other riders where space is tight. The seat tube angle is generally 73 degrees and the rider’s position is often upright. The hands are positioned on top of the hoods to allow for easy shifting and braking. This position allows for maximum power transfer when pedaling, especially climbing, and quick response time when in a pack of riders.

Tri-specific bikes

Tri bikes also handle well but in a different way. Tri bikes are made to go fast while utilizing rider energy efficiently and even conserving energy to some extent (remember – the bike is only 1/3 of the race). In order to accomplish this, tri bike geometry has a steeper seat tube angle, usually 76-78 degrees. The head tube angle is usually a little less aggressive, the top tube is slightly shorter, and often the front end slopes. The chain stay is also often one centimeter or so shorter. This geometry allows the rider’s hips to remain open while riding in the aero position

So now my friends, road bike or tri bike?

There’s definitely a difference between a road bike and tri bike. Will the differences benefit your riding style and ability? Some people can read and relate to the differences between the two geometries and understand how the differences might affect their own riding / training immediately. It might not be so clear for others. It is always a good idea to meet with a certified tri bike fitter and have them evaluate you in person.

For your question specifically, I would say

a. consider the above points
b. evaluate your future goals
c. and definitely meet with a certified tri bike fitter and get evaluated.

Would a steeper seat tube angle be advantageous? Probably. Remember, you still have to get off the bike and run with that 250 lbs...lolz. Any energy savings that your quads take advantage of during the bike will benefit you in the run. There’s one in favor of the tri bike.

If you were just getting into triathlons and already have a road bike, then sure, by all means throw on a clip-on and go to town. But if you are buying a bike to train for triathlons specifically and that’s what you enjoy, why even consider a road bike?

You answered your own question. Train with what you are going to race with. Ideally…cross train. Don’t trade in that old road bike. Save it...as a road bike. No clip-ons. It’s not worth much. It’s worth more to you as a bike to cross train on, ride with friends and as a spare.

Keep on runnin' mate!
