What size chainring do I need for a triathlon?

If you’ve sustained any damage from crashing your bike, or it topples over when you lean it on something, you should consider upgrading.

Will shorter cranks help my knees?

Crank length can be used as a tool to improve fit related issues impacting comfort, power, and aerodynamics. Moving to a shorter crank can improve: Comfort: A shorter crank length reduces range of motion at the knee (extension and flexion), hips, and low back.

Are longer or shorter cranks better?

While longer cranks do produce more torque, they also decrease cadence for a given effort because the turning circle is larger. Likewise shorter cranks produce less torque, but cadence increases for the same effort because the turning circle is shorter.

Are longer crank arms better?

When viewed from this perspective, a bicycle crank is considered a lever, and hence, any increase in the length of the cranks has the potential to provide the rider with extra leverage. Then, longer cranks allow a rider to develop more speed than shorter cranks, even when the difference is as little as 2mm.

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 a bigger chainring do?

The size of a chainring (often expressed in terms of the amount of teeth on it, e.g. a 53t ring) plays a direct role in your bike’s gearing, with bigger rings meaning a higher (harder to push) gear and smaller rings a lower (easier to push) gear.

Can you race with compact crankset?

How fast do pro triathletes run?

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.

What is a 52 36 crankset?

A semi-compact chainset, sometimes called mid-compact or faux pro, has a 52-tooth outer chainring and a 36-tooth inner chainring. This means that the biggest gears aren’t quite as big as those of a 53/39 chainset but they’re not far off, and they’re larger than those of a compact.
