There are bicycles for every form of competition from road sprints to climbs, and from XC to downhill. And then there are triathlon bikes. For those who still don’t know, a triathlon consists of a swim, a foot race and a bike race, all on the same day and without a break except for a quick change into an appropriate gear.

How are triathlon bikes different from road bikes?

The main difference between road bikes and triathlon bikes lies in the positioning of the seat. On triathlon bikes, the seat tube is steeper than on a road bike, which forces the hips to sit forward and ensures that the rider experiences less tension on the quadriceps and hamstrings. Road bikes typically have a 72-degree seat tube angle while a triathlon bike has an angle of about 78 degrees.

Because drafting is not legal in most triathlons, all triathlon bikes are wind-tunnel tested during the design phase to be sure they are efficient and save the rider as many watts as possible during the ride. A triathlon bike also features aero bars that place the rider in a very aerodynamic position so they’re able to ride (at least somewhat) comfortably for hours at a time. In addition, deep carbon-fibre wheels on triathlon bikes increase aerodynamics. Triathlon bike races are usually long and demanding. They span from 10 km for the super sprint triathlon to 180 km for the Ironman triathlon. The standard and Olympic distance is 40 km. Therefore, with triathlon bikes, the rider needs to be prepared for emergencies such as a puncture.

A quick guide to the best triathlon bikes for beginners

If you’re crazy enough to think about becoming a triathlete, you probably already have all the equipment you’ll need for the swim and the run. But triathletes need triathlon bikes too. The first question is what’s best for a beginner. www.triathlete.com suggests that you may be better off, in the beginning, at least, with a road bike. “Road bikes are versatile and well suited for just about anything,” they write. “Triathlon bikes can be tricky to handle; they are made for going fast in a straight line and are not ideal for group riding or easy endurance rides. Every triathlete should own a road bike but not every triathlete should own a tri bike.”

But riders who really want triathlon bikes need to make sure it’s a good fit – literally. A bad fit when it comes to triathlon bikes will hamper your performance, limit your pleasure, and can even lead to injury. Check the fitter database on Ibfi-certification.com, or ask around for a recommendation of some fitters experienced with triathlon bikes in your area, if there are any.

Triathlon bikes: Are aluminium or carbon frames better?

The next question you need to ask about triathlon bikes is: aluminium or carbon frame? The decision will make a difference in how the bike feels during the ride. Aluminium frames can be as light as those made of carbon fibre. But aluminium tends to put up a harsher ride. Can’t afford a carbon-fibre frame? You can still get a good ride on the aluminium frame by matching it with high-quality tires and making sure they are always inflated to the recommended pressure.

Triathlon bikes or road bikes: which option is best for you?

A good road bike for a beginner is the Cannondale CAAD12 105 with Shimano 105 parts. It will set you back about $1,600. In terms of beginner triathlon bikes, one is the gorgeously designed Ventum Z with Shimano Ultegra parts, priced at about $3,500.

There’s no doubt that cycling challenges can be a great motivation booster for the right person. The only question I still have is: are you sure you want to do this?
