Comparing the efficiency of 160mm and 165mm cranks

[corn oil]

Whats the real difference in efficiency between 160mm and 165mm cranks? Ive seen some claims that the slightly longer 165mm crank provides a more efficient pedal stroke, but is that just marketing hype or is there actual science backing it up? Does the increased leverage of the longer crank really result in more power output, or is it just a case of diminishing returns? And what about the trade-offs - do the longer cranks put more stress on the knees and hips, potentially leading to injury or discomfort?

It seems like the majority of professional riders are still using 170mm or 172.5mm cranks, so why would anyone choose to go shorter? Is it purely a matter of personal preference, or are there specific situations or riding styles where shorter cranks are actually beneficial? And what about the impact on bike fit - do shorter cranks require a different saddle height or handlebar position to maintain optimal ergonomics?

Ive also seen some discussion about the importance of crank length in relation to rider height and inseam. Is there a specific formula or guideline for determining the ideal crank length based on a riders physical characteristics? Or is it more of a trial-and-error process, where you just have to experiment with different lengths to find what works best for you?

Its also worth considering the impact of crank length on different types of riding. For example, do shorter cranks provide an advantage in criteriums or other high-cadence events, where quick acceleration and agility are key? Or are they more suited to endurance riding, where a more efficient pedal stroke can help conserve energy over long distances?

Ultimately, what are the key factors to consider when deciding between 160mm and 165mm cranks, and how can riders make an informed decision about which length is right for them?

Ah, the age-old debate of 160mm vs 165mm cranks - a real thrilling topic, I'm sure you'll agree. To answer your question, yes, there is a difference, but whether it's significant or just marketing fluff is another story.

The theory is that longer cranks provide more leverage, resulting in a more powerful pedal stroke. However, this comes with potential downsides, such as increased stress on knees and hips. So, it's swings and roundabouts, really.

As for why pros stick to longer cranks, well, it's probably just tradition and what they're used to. But that doesn't mean shorter cranks can't have their place. For instance, if you're vertically challenged or have particularly pesky knee issues, shorter cranks might be your knight in shining armor.

Now, when it comes to bike fit, shorter cranks can indeed affect saddle height and handlebar position. But fear not, it's not rocket science - just a bit of trial and error should see you right.

And as for crank length in relation to rider height and inseam, there's no one-size-fits-all formula. It's a case of finding what works for you, which might involve some experimentation.

Finally, the impact of crank length on different types of riding - crikey, where do I start? Shorter cranks might help in crits or high-cadence events, but then again, they might not. It's a bit of a wildcard, isn't it?

In conclusion, the key factors to consider are your own body dimensions, riding style, and preference. And as for making an informed decision? Well, that's why we have these delightful forums, isn't it? To share our collective wisdom and help each other out. So, keep the questions coming, and let's keep this party going! ‍

Longer cranks, like 165mm, may offer increased leverage and power output, but they can also put more stress on knees and hips, potentially leading to discomfort or injury. Contrary to popular belief, professional riders using longer cranks doesn't mean they're superior. It's about personal preference and riding style.

For instance, shorter cranks, such as 160mm, might be advantageous in criteriums or high-cadence events where quick acceleration and agility are crucial. However, they might not be as efficient in endurance rides.

Crank length should also be considered in relation to rider height and inseam. A general guideline suggests adding 10% to your inseam length for ideal crank length, but it's often a trial-and-error process.

In the end, riders must weigh the benefits and drawbacks of each crank length and make an informed decision based on their unique needs, riding style, and physical characteristics. Don't let marketing hype sway you - do your research and experiment to find what works best for you.

Longer cranks may offer increased leverage, but they can also strain knees & hips, potentially causing discomfort or injury. Contrarily, shorter cranks may compromise power output. It's crucial to consider riding style, physical characteristics, and bike fit. There's no one-size-fits-all answer, and riders must experiment to find their ideal crank length. Ignoring this could lead to inefficiency or injury.

The great crank length debate rages on. While some claim 165mm cranks offer increased efficiency, others argue it's just marketing hype. The science is murky, with studies suggesting minimal power output differences between lengths. However, knee and hip stress do rise with longer cranks, potentially leading to discomfort or injury.

Pro riders' continued use of 170mm or 172.5mm cranks may simply reflect tradition and personal preference, rather than objective advantages. Shorter cranks might benefit specific situations or riding styles, and bike fit is indeed impacted, requiring adjustments in saddle height and handlebar position.

Crank length selection is personal and multifaceted, tied to rider height, inseam, and riding style. Yet, a rigid formula for crank length selection is elusive. Many cyclists rely on trial and error, experimenting with various lengths to find their optimal fit.

For criteriums or other high-cadence events, shorter cranks may offer quicker acceleration and agility, while longer cranks suit endurance rides, conserving energy with a more efficient pedal stroke. It's essential to weigh these considerations and carefully evaluate which length is right for you.

While some claim longer cranks offer more power, it's not that simple. Increased leverage can strain knees & hips, potentially causing discomfort or injury. Pro riders often use 170mm or 172.5mm, but that doesn't mean it's one-size-fits-all. Crank length should consider rider height, inseam, and riding style. For criteriums, shorter cranks can enhance agility, while endurance riders might prefer longer ones for efficiency. It's about finding the right balance for you, not blindly following trends.

Y'know, some folks think longer cranks = more power. But lemme tell ya, it ain't that straightforward. Sure, you get more leverage, but it can stress your knees & hips, leading to discomfort or injury. Short cranks? They might sacrifice power, but they help with agility in crits.

Truth is, there's no one-size-fits-all. Rider height, inseam, and style matter. Pros might use 170mm or 172.5mm, but that doesn't mean you should. It's about striking the right balance for you, not mindlessly following trends.

So, before you jump on the longer crank bandwagon, think about your riding needs. Don't let trends dictate your bike fit. Personalize it, experiment, and find what works best for you.

Look, longer cranks ain't a guaranteed power boost. Yeah, you get more leverage, but there's a risk of increased knee & hip stress, which could lead to discomfort or injury. Short cranks might sacrifice some power, but they boost agility in crits.

Remember, one-size-fits-all is a myth. Rider height, inseam, and style matter. Pros using 170mm or 172.5mm doesn't mean you should. It's about finding the right balance for you, not blindly following trends. So, think carefully about your riding needs before hopping on the longer crank bandwagon. #cycling #bikefit

Oh, finally someone gets it. Longer cranks? Not a power guarantee. Yeah, leverage, but hello, knee & hip stress! Short cranks, sure, less power, but more agility in crits. Remember, one-size-fits-all is a myth. It's about finding the right fit for you, not following trends blindly. So, think about your needs before jumping on that bandwagon. #forumconvo #cyclinglife
