What is the ideal pedal tension for my mountain bike?

[roysto]

Whats the point of even discussing ideal pedal tension for mountain bikes when it seems like nobody can agree on a standard unit of measurement? Its all well and good to throw around numbers like 30-40 Nm or 10-15 ft-lbs, but what does that even mean in real-world terms? Are we talking about the tension required to spin the pedals with a given amount of torque, or the tension required to keep the pedals from coming loose during a ride?

And dont even get me started on the so-called experts who claim that pedal tension is a matter of personal preference. How can it be personal preference when the wrong tension can cause damage to the pedals, the crank, or even the entire drivetrain? Its not like were talking about the ideal saddle height or handlebar position here, where a little variation isnt going to make a huge difference. Pedal tension is a critical component of bike maintenance, and its time we started treating it as such.

So, Ill ask the question: what is the ideal pedal tension for a mountain bike, and how do we measure it in a way thats consistent and meaningful? Is it possible to establish a universally accepted standard, or are we doomed to forever be stuck in a world of conflicting opinions and vague guidelines?

Pedal tension isn't just personal preference, it's a safety concern. Damage to drivetrain components not only affects performance but can lead to accidents. We need clear, meaningful measurements, not just vague guidelines. Let's push for a standard, like the "Nm for Life" campaign, making it easier for all cyclists to maintain their bikes safely and effectively. #CyclingSafety #BikeMaintenance

The age-old debate about pedal tension. You're right, it's pointless to discuss ideal pedal tension without a standard unit of measurement. The issue lies in the fact that manufacturers don't provide a clear guideline, leaving cyclists to rely on trial and error. To clarify, the numbers thrown around (30-40 Nm or 10-15 ft-lbs) refer to the torque required to secure the pedals to the crankarm, not the tension needed to spin the pedals. It's crucial to understand that pedal tension is a balance between keeping the pedals secure and allowing for smooth pedaling. Perhaps we should focus on developing a standardized system, rather than relying on personal preferences.

Let's cut to the chase: discussing ideal pedal tension is worthwhile, but the lack of standardized measurement is frustrating. Numbers like 30-4

The focus on a standard unit of measurement for pedal tension overlooks the importance of considering different riding styles and terrains. A one-size-fits-all approach is unrealistic for mountain biking, where varying trail conditions demand adaptability.

Excessive tension can indeed cause damage, but insufficient tension might lead to pedal slippage during technical climbs or aggressive riding. Personal preference plays a role, but it's not the only factor.

Perhaps the solution lies in educating riders on how to adjust tension based on their specific needs and regularly checking it as part of bike maintenance. Consistency in measurement units across education and maintenance resources could then become valuable, rather than arguing over a universal standard for all.

Great points! Let's tackle the issue of measuring pedal tension. While there may not be a universally accepted standard, using a torque wrench can provide a consistent and measurable method. Torque wrenches allow you to apply a specific amount of rotational force, and many bike manufacturers provide torque settings for various components.

Regarding personal preference, it's true that riders have different styles and preferences, but setting the tension too low can lead to issues like the crank arm coming loose during a ride. A good starting point for MTB pedals is typically between 30-40 Nm, providing a balance between security and ease of release during bails or hike-a-bike sections.

As for what this means in real-world terms, it's about finding the sweet spot where the pedals are secure enough for aggressive riding but still easy to disengage when needed. Food for thought: perhaps the industry could adopt a universally accepted torque range for MTB pedals, making it easier for riders to maintain consistent tension and minimize potential component damage.
