What do I need to know about triathlon bike gearing needs?
- Your triathlon bike gearing needs can also change from venue to venue so be aware of the possible elevation changes typically provided by event sites.
Where are the gears on a triathlon bike?
Your standard racing bike (triathlon or road) has 10 gears attached to the rear wheel, collectively known as the cassette. Each one of those gears is a cog. Up front, attached to your cranks, are the gears we call the chain rings.
Should I stop pedaling when changing gears?
You must be pedaling when you change gears. That’s because the chain has to be moving in order for the derailleurs to “derail” the chain from sprocket to sprocket. If you click the shifters without pedaling, the gears won’t change until you do start pedaling, and when you do, you’ll hear some very disconcerting noises.
Do TT bikes have gears?
Gearing. Riders tend to push bigger gears on their time trial bike than they do on their standard road bike. Many find it possible to produce more power this way, and they don’t need to be ready to respond to unexpected accelerations like they do when riding in a group.
How do you shift gears on a bike?
To operate the shifters you push the lever sideways until you hear a click. For most mountain and hybrid style bikes with flat bars, you shift the gears by using set paddles that you operate with your thumb. Some bikes operate with “grip shifters”, or a dial that is located to the inside of where you place your hands.
Do TT bikes have brakes?
On a modern time trial bike, the brakes are usually hidden out of the airflow. This means that the front brake is sited behind the fork and the rear tucked behind the seat-tube near the chain-stays. The brake levers are located on the bullhorns and are often blade thin to cut through the wind.
What are DI2 gears?
Di2 stands for “Digital Integrated Intelligence” – Shimano’s version of electronic shifting. DI2 gives you instant, accurate, lightning-fast shifts the first and every time, at the push of a button. Even in the most extreme conditions, shifting is precise and controlled.
What gear should I use on a flat road?
Middle Gear This is a great gear for everyday terrain when you’re cruising along on a flat road or on undulating terrain. You want some resistance, but not too much. If the road goes up and down a bit, you’ll probably flick between the rear gears to cater for changes.
What does crossing the chain mean?
Cross-chaining is when you’re in your big chainring and the biggest cog on your back cassette, or on your small chainring and your smallest cog. The problem is that this stretches your chain diagonally to its limits, and needlessly so, since you could just shift to your other chainring and find a similar gear ratio.
What is STI in bike?
Dual Control or Shimano Total Integration (STI) is Shimano’s name for the integrated brake and gear shifter lever. The Shimano shifter system works by moving the whole brake lever to change gear in one direction, and using a smaller integrated lever inside the main brake lever to change in the other direction.
