Gotta agree, I just couldn't stop thinking that!

Intense Spider Pro – Review
The bike I ride the most is a 80mm travel single speed with 120mm forks and 26" wheels. It may not be the fastest, but it is the most fun.

Pinkbike Poll: How Do You Want Your Bike Biased?
80% of my riding is on a 80mm travel singlespeed. It's designed to be good on gently downward trails, but that are super tight and nadgery. It certainly not an XC singlespeed. It has a slack head angle and low BB. How does this fit into this new marketing classification?

Pinkbike Poll: How Do You Want Your Bike Biased?
I find this percentage trend a bit strange. If you don't shuttle, all riding is 50% up and 50% down. You have to pedal up a hill to ride down. Even road riding is 50%. It only pushing or shuttling that can change this percentage, and therefore it just becomes an indication of how often this happens.

It's down to manufacturing. To make a square tube to high tolerance values is very hard and therefore expensive.

Ask Pinkbike: Carbonphobia, Choosing a Rain Shell, and Hydro-Pack Alternatives
Agreed, but it's the stress raisers in the ally parts that lead to the local stress exceeding the endurance limit. A poor weld or a local scratch for example may be the culprit. Admittedly I've never seen bars that look like they have a fatigue failure. But I've seen many ally frames snapped due to cracks growing from bad design features or welds. What I find interesting is the varied opinions on carbon parts. A lot of it from what seems to be people qualified to comment. It just goes to show its a new material and that our understanding is relatively immature. Also, different engineerings fields and applications focus their attention onto different issues. All good fun...

Ask Pinkbike: Carbonphobia, Choosing a Rain Shell, and Hydro-Pack Alternatives
I think there a bit of misunderstanding of the science in this report. "Scratch the hell" out of an aluminium bar and you'll introduce a whole load of stress raisers that might lead to a crack initiation site and consequently a fatigue failure. This is not good. This is not a concern with carbon fibre, which is pretty insensitive to fatigue loading and crack propagation. Over tighten the clamp on a aluminium bar and you might in the worst case cause a little bit of plastic deformation but it's highly unlikely and not a massive concern. Crush a carbon bar and you may cause a bit of matrix failure and delamination. This is not good and may lead to premature bar failure. I expect the problems with sharp edges on stems with carbon bars are not the consequent scratches but the local crushing failure? So don't scratch your ally bars. And scratching your carbon bars isn't the end of the world. But crushing your carbon bars (or other impact damage) is not a good idea.

I'm a stress engineer. And I think I am very creative and a good eye for aesthetics. But I understand your point that people tend to be experts in their field and trying to work together is the difficult part. See link below... Https://www.facebook.com/mrbennsamazingadventures/posts/866953193344506
