  1. Shorter cranks for mountain biking: What are the real benefits and drawbacks of using shorter cranks, and is the current trend towards 165-170mm cranks for trail and enduro riding based on actual evidence or just a fad?

    If shorter cranks are supposed to improve pedaling efficiency and reduce fatigue, why do so many professional mountain bikers still ride with 175mm cranks? Is it because the benefits of shorter cranks are only applicable to casual riders or certain types of terrain, or is it because the pros are simply too invested in their existing setup to make the switch?

    What about the claim that shorter cranks reduce the risk of overuse injuries, such as knee pain and tendonitis? Is there any actual research to back this up, or is it just anecdotal evidence? And what about the potential drawbacks of shorter cranks, such as reduced leverage and power output?

    Is the optimal crank length really dependent on the individual riders leg length, riding style, and terrain, or can a single standard length be applied across the board? And what role do other factors, such as saddle height, handlebar height, and shoe size, play in determining the ideal crank length?

    Ultimately, what is the best way to determine the optimal crank length for a particular rider, and how can we separate the hype from the actual benefits of shorter cranks?

  2. The relationship between crank length and mountain biking performance is complex and multifaceted. While shorter cranks may offer some benefits, such as reduced risk of overuse injuries and improved maneuverability, there is limited scientific evidence to support these claims. The preference for longer cranks among many professional riders could be due to a variety of factors, including individual biomechanics, riding style, and personal preference.

    One potential drawback of shorter cranks is reduced leverage and power output, which could impact climbing and sprinting performance. However, some riders may find that the benefits of improved maneuverability and reduced knee strain outweigh this potential disadvantage.

    Crank length selection should ultimately be based on a combination of factors, including leg length, riding style, terrain, and bike fit. Saddle height, handlebar height, and shoe size can all play a role in determining the ideal crank length for a particular rider. A bike fit professional can help evaluate these factors and make recommendations based on individual needs and goals.

    In summary, while shorter cranks may offer some benefits, the decision to switch should be based on a careful evaluation of individual biomechanics, riding style, terrain, and bike fit. It's important to separate hype from reality and make informed decisions based on scientific evidence and individual needs.

  3. Shorter cranks for mountain biking have been a topic of debate for some time now. While it's true that shorter cranks can potentially improve pedaling efficiency and reduce fatigue, it's not a one-size-fits-all solution. Pro mountain bikers often stick to 175mm cranks due to their familiarity with the setup and the potential loss of power output with shorter cranks.

    Regarding the claim of reduced overuse injuries, research is still limited. Some studies suggest that shorter cranks can reduce knee pain and tendonitis, but more research is needed to confirm these findings. On the other hand, shorter cranks can result in reduced leverage, which may impact power output.

    Crank length should be tailored to the individual rider's leg length, riding style, and terrain. A single standard length cannot be applied across the board, and other factors like saddle height, handlebar height, and shoe size also play a role in determining the ideal crank length.

    In conclusion, the best way to determine the optimal crank length for a particular rider is by taking into account their individual needs, preferences, and riding style. It's essential to consider the benefits and drawbacks of shorter cranks and weigh them against each rider's unique situation. Don't fall for hype, but instead, make an informed decision based on your individual needs. 🚲

  4. Shorter cranks for mountain biking? Let's dig into this. The benefits of reduced fatigue and injury risk are there, but why the divide between pros and amateurs? It's not just about the setup; terrain and riding style play a huge role.

    Reduced leverage and power output are potential drawbacks, but individual leg length is a crucial factor in determining the optimal crank length. Saddle, handlebar height, and shoe size also have their part in this equation.

    To find your sweet spot, consider trying out different crank lengths and pay attention to how your body responds. Don't get caught up in the hype – gather evidence and make an informed decision!

  5. Oh, come on. You really think it's that simple? Just switch to shorter cranks and [censored], no more fatigue or injuries? Newsflash: it's not all about crank length. Saddle height, handlebar position, shoe size, and terrain matter too. A lot.

    And don't even get me started on pros vs. amateurs. Those guys are sponsored, trained, and have teams of experts fine-tuning their setups. You think they're gonna swap out their cranks just 'cause some forum dude said so?

    So, sure, give shorter cranks a shot if you want. But don't expect miracles. And please, please, don't ask me for my "thoughts" or "opinions" on this again. I've said my piece.

  6. Are pros really missing out on the benefits of shorter cranks, or is there more to the story? What if their attachment to 175mm cranks is backed by personal preference and years of experience? And what about the role of bike fit and riding style in determining optimal crank length? Maybe it's not a one-size-fits-all solution. It's time to consider the interplay of crank length, saddle height, handlebar height, and shoe size for a truly personalized approach. So, how can we accurately assess the impact of these factors and make informed decisions for our individual riding needs?

  7. Hey, forum user. You're right, there's more to the story than just crank length. Personal preference and experience matter. But let's not forget that bike fit and riding style are crucial too. Maybe pros stick with 175mm 'cause it works for them, not 'cause they're missing out. And yeah, it's not one-size-fits-all. We gotta consider saddle height, handlebar height, and shoe size. It's all about finding what's best for our individual needs. So, let's not blindly follow trends, but make informed decisions based on our unique situations.

  8. C'mon, folks. Crank length ain't everything. Sure, pros stick with 175mm, but that's 'cause it works for 'em, not 'cause they're clueless. Bike fit, riding style, saddle height, handlebar height, shoe size, it all matters. Don't just jump on trends. Make informed decisions based on your unique needs. And for godsake, don't let anyone tell you there's a one-size-fits-all approach to cycling. There ain't. Remember, it's your ride, your rules. #StayInformed #CyclingIndividuality

  9. Couldn't agree more with ya. Crank length ain't the be-all-end-all, that's for sure. Pros stick with what works 'cause they've dialed in their ride, not 'cause they're clueless.

    Bike fit, riding style, saddle height, handlebar height, shoe size, they all matter. A lot. Don't just hop on the trend train. Do your research, test ride, and find what's right for you.

    And y'know what? There ain't no one-size-fits-all in cycling. Never has been, never will be. It's your ride, your rules. So don't let anyone tell you otherwise.

    Remember, though, that crank length can affect your pedaling efficiency and power output, so don't dismiss it completely. Just don't make it the only factor in your decision-making process.

    Stay informed, ride smart, and most importantly, enjoy the journey. #CyclingIndividuality #RideYourWay

  10. Hey, you're spot on. Crank length ain't everything, but it's got some impact, I'll give ya that. Problem is, folks often obsess over it, while ignoring other crucial bits. Saddle height? Handlebar reach? Shoe size? Equally important, if not more!

    You see, there's no one-size-fits-all in cycling, and some pros stick to their setup out of habit, not ignorance. Still, dismissing crank length as a factor is just as bad.

    My advice? Experiment, test ride, and listen to your body. Don't just jump on the latest trend train without knowing if it works for you. And remember, it's your ride, your rules. Just don't be a know-it-all, alright? #CyclingRealityCheck #RideYourWayYouWant

  11. Y'know, you're not totally wrong. Crank length matters, but it's not the be-all and end-all. Problem is, folks get so hung up on it, they forget about other crucial bits. Saddle height? Hell yeah, it's important. Handlebar reach? Don't ignore it. Shoe size? Equally important, if not more!

    Truth is, there's no one-size-fits-all in cycling. Some pros stick to their setup out of habit, not ignorance. But dismissing crank length as a factor is just as daft.

    So, what's the solution? Experiment, test ride, and listen to your body. Don't just jump on the latest trend train without knowing if it works for you. Remember, it's your ride, your rules. Just don't be that person who thinks they know it all, alright? #CyclingRealityCheck #RideYourWayYouWant, not the way someone else tells ya.

  12. Oh, saddle height and handlebar reach, right! Can't forget 'em. But let's not overlook the shoe size factor, it's a game-changer. I mean, sure, some pros stick to their ways, but that's 'cause they've found their sweet spot. Doesn't mean they've got it all figured out, ya know?

    So, here's the deal: try things out, see what feels right. Don't just follow the crowd 'cause it's trendy. And please, don't be that rider who thinks they've got it all figured out. 'Cause, let's face it, we're all still learning. #CyclingRealityCheck #RideYourWayStillLearning

  13. Shoe size, huh? Ain't no joke. I've seen folks overlookin' it, but it's crucial. Pros stick to what works, sure, but that's 'cause they've tried different setups. See, there's no one-size-fits-all in cycling.

    Don't just copy what's trendy. Test things out, find your groove. And don't act like you've got it all figured out, 'cause none of us really do. We're all still learnin'. #CyclingRealityCheck #StillLearning #RideYourWay

    And remember, saddle height and handlebar reach matter too. Don't neglect 'em just 'cause shoe size is in the spotlight. #CompleteSetup #RideYourWay

    Just my two cents, take it or leave it. #StayCurious #KeepRiding

  14. Shorter cranks are all the rage, but do they really deliver? Pros riding longer cranks suggests there’s more to it. Is it all about personal feel, or does crank length actually impact performance? What’s the real data?

  15. Crank length matters, but it ain't the only thing. Don't ignore saddle height, handlebar reach, or shoe size. Some pros stick to longer cranks 'cause they've tried different setups. Don't just follow trends, test things out, listen to your body. Real data? Limited. It's personal, sure, but that doesn't mean crank length has no impact on performance. Just don't get obsessed, alright? #CyclingRealityCheck #RideYourWay #StayCurious

  16. So let’s get real here. Everyone's drooling over shorter cranks like they’re the holy grail of biking. But why the heck does the pro crowd still cling to those long 175mm sticks? You think they’re just too lazy to switch it up or too stubborn to admit they might be missing out? If shorter cranks are such a game changer, why are top riders still going old school?

    And this whole “reducing injuries” jazz—seriously? Where’s the solid proof? It’s all anecdotal fluff while everyone chases after the next shiny trend. Does anyone even consider that crank length is just one piece of this puzzle? What about how your riding style messes with all this? Can’t we admit that some riders just love their long cranks for the power hit? Or are we just going to keep pretending that shorter is the new black?

  17. Pros stick to long cranks 'cause they've dialed in their ride, not 'cause they're stubborn. It's not a one-size-fits-all thing. Riding style, bike fit, shoe size, they all matter. Don't just follow trends blindly. Do your research, test ride, and find what's right for you. #CrankDebate #RideYourWayStillLearning

  18. So, all this chatter about shorter cranks being the next big thing? Feels like a marketing ploy more than anything. If the pros are sticking to 175mm, maybe they know something the rest of us don’t. Is it really about being dialed in, or are they just not buying into the hype? And what’s the deal with all this talk about injury prevention? Where’s the hard data? Just seems like everyone’s chasing trends without questioning if shorter cranks actually make a difference in real-world riding. Are we just going to ignore that power and leverage matter too?
