there have been many tests in the wind tunnel and these tests often show in an Ironman event that a TT or Triathlon bike can be up to 3kph quicker, while this is a general figure you may find this slightly more or less depending on your position, wheel choice and average speed.
How much faster is a tri bike over road bike?
The BikeRadar website claims the advantage a TT bike gives you is 60-70 watts at 40 km/h, that is, it takes 270-280 watts to ride a road bike at that speed and 220 watts to ride a TT bike. Translated into seconds, a TT bike gives you 9 seconds per kilometre advantage.
How much faster will a tri bike make me?
In general you will see a 1.5 mph – 2 mph boost in speed between a TT and a road bike… assuming the rider is using regular shorts, jersey and helmet along with no aero wheels. Most of that is due to the differing rider position (i.e. more aero).
Is triathlon bike faster than road bike?
A tri or TT bike is noticeably faster than a road bike once your average or effective speed (your pace + wind speed) gets above about 20mph. There are 2 reasons why a tri/TT bike is faster: #1 aerobars, #2 aero wheels. Roadbikes can use aero wheels.
Does a tri bike really make a difference?
The most notable difference is the design, or geometry of the frame of each bike. Triathlon bikes have a steeper angle of the seat. … The steeper angle allows the user to travel at a faster rate because you can bend your body down lower which reduces wind resistance.
Why are tri bikes faster than road bikes?
Triathlon bikes are designed to make riders faster. … The seat tube is closer to vertical than a road bike’s. This steeper geometry places the rider’s hips over the crankset which engages their quadriceps more for increased power.” Tri bikes are more aerodynamic and are “faster” than road bikes.
Why are tri bikes heavier?
A triathlon bike is heavier than a road bike by 2- 4 lbs or 1 to 2 kg. The reason is that the aim is to make a triathlon bike more aerodynamic rather than lightweight as it is in road bikes. The triathlon bikes come with bigger aerofoils and bigger frames than the road bike.
How much faster is aero position?
In simpler terms, the aero savings achieved by simply moving from a relaxed hood position to the horizontal arms position at 45kph would result in a 1.65kph speed increase at the same wattage, which results in a two minute time saving over the course of a 40km TT.
How much faster are tri bars?
After installing aero bars, riders typically find that they’re going 1 to 2 mph faster at the same level of effort.
Can I use a tri bike as a road bike?
You can turn a normal road bike into a TT bike fairly easily but a TT bike is very specialist. You can’t use it in road or crit races and they’re frowned on in Sportives. Less safe in traffic too cos of the more head down position.
Is a cheap TT bike faster than a road bike?
This new position was a substantial 6mins 51s faster than the ‘tops’ road bike position, and 3min 48s faster than the ‘drops’ position.
…
Watch: how much faster is a time trial bike, really?
| Bike/position | Watt saving vs baseline |
|---|---|
| AIR road bike, clip on bars, optimised*, at 40kph | 83 |
| TTE time trial bike, to travel 40kph, at 40kph | 86 |
Are triathlon bikes good for long distance?
Yes. However, triathlon bikes are not tour bikes. Triathlon bikes can be ridden for long distances, but they are designed for relatively straight and flat ridding. You wouldn’t want a triathlon bike on any multi-day gran-fondos or do any serious mountain climbing or descending with a tri-bike.
Does tri bike save your legs?
Tri bike saves your legs by making you more comfortable in a forward leaning position and reducing the drag of your body. And the frame helps a little. So if a tri bike saves you 10 min over 112 miles then that’s 10 min less on the bike and thus saved for the run.
Is it worth getting a TT bike?
Triathlon bikes are almost worthless outside of triathlon and time trialing. They’re not as safe, as comfortable, or as easy to handle as a road bike. … In fact, you can still be pretty competitive on a road bike with some solid training and coaching.
Why are TT bikes heavier?
Heavier. A time trial bike is typically 1-2kg heavier than a road bike. This is because the main focus is making a time trial bike more aerodynamic rather than lightweight. TT frames tend to be heavier because of bigger ‘aerofoils’ and bigger frames.
