4 New Materials That Could Improve Carbon Fiber
Do catastrophic carbon failures actually occur in the wild? I’ve broken at least 6 carbon frames all of which failed with a pop delaminates and left a crack and were ridden home gingerly without blowing to bits ...sure if loaded over the absolute limit it can be catastrophic but I feel most cases are not like that and if they are it’s a bad design or used for something it shouldn’t be

Burning Question: What's Next for Mountain Bike Helmet Safety?
I find it an absolutely terrifying revelation to the shittiness of bike helmets and their regulatory standards. that over 3000 of 10,000 respondents in the pink bike injury poll have experienced concussions. We can do better. The test apparatus shown also look totally ridiculous. Someone start a go fund me. helmet mounted action camera with accelerometers and black box and a small secondary camera watching the hemet. Send the data and injury details to a central data base....get a discount on a replacement helmet. Give the guys working on this a pile of real world data.....GoPro Here's looking at you.....

Field Test: 12 Bikes Hucked to Flat in Gratuitous Slow Motion
@wallheater: pause the video draw lines.... 1 for lowers, 1 for stanchions and 1 for head tube. in the air vs at impact vs 3/4 travel. It's tricky cuz a lot of crap is moving in weird ways you wouldn't expect. (Tire stops bike keeps moving forward) There is some flex notably between the stanchions and lowers but BARELY perceivable. rotation of the fork around the axle is massive but head tube stanchions and lowers stay in close alignment from the unloaded condition as far as the human eye is concerned I'm open to being wrong cuz i like learning new things and further questioned my initial statement due to the feedback I had from you guys but on further detailed review, I stand by it....majority of what is being seen is not flex.

Field Test: 12 Bikes Hucked to Flat in Gratuitous Slow Motion
@gabriel-mission9: I realize when any load is applied some flex is present . whether it is significant or visibly detectable is what I'm getting at. what is predominantly VISIBLE in this video is the pivoting of the fork on the front axle. worst case of this is 1:38 get a good screen and reclick that section a few times. (you can't do this with a touchscreen phone) The flex (although present) is BARELY visible. the pivot Is VERY obvious and I believe most people are not making this distinction. This pivot occurs because the tire stops rotating on landing it becomes difficult to begin rotating as it's basically a square on the ground just after impact as such the fork pivots on the front wheel axle a bit because this is the path of least resistance to stay aligned with the headtube. Id like to include photo's in my response to clarify further. But based on your response attacking my qualification it doesn't appear you would be open to discussion or further thought against your initial assumptions. So likely wont be a fruitful discussion. If you care to take the time slow it down an notice the line between the shock and the head tube barely wavers from straight on impact the tire stops then the fork pivots forward on the axle to stay in line with the headtube. To your point the blue yeti I find the flex to be visible on that model. but others the visible effect is dominated by a pivot rather than a flex.

NOT FLEX Being an acual enigneer, The forks are not flexing they are pivoting on the axle. When the front tire flattens out on some severe flat landings it stops rotating. the bike continues to carry it's momentum forward . this results in the fork pivoting forward on the axle to stay aligned with the forward moving head tube on the frame . Its because the forks are quite stiff and the tire stops that this occurs. Youll notice you don't see this pivoting when the landing is such that the front tire keeps rotating at reasonable speed. Only when the tire stops due you get this pivot effect you guys are misreading as flex. Place your finger on 1:38 and click that over and over. you'lll see what I'm talking about.

Video: 7 Years of Adventure with Tito Tomasi
Great video! Well done vids like this give me a mild anxiety that make me think I need to do more with my life. Then I think if I captured video highlights of the epic adventures and moments in the last 7 years of my life it would also make an unreal video....and I’m satisfied that I’m drinking coffee watchig pinkbike vids enjoying the good editing work of others.

Opinion: Why Have Bike Makers Ignored this Grassroots Fix?
I find the wrap looks pretty crappy especially compared to new paint. looses all the deep wet shine. and a good application is rare. Yeah it'll make the bike look better in 2 years and help with resale but it's like one of those black car bra's You make YOUR bike look crappier in order for someone ELSE to enjoy It only really protects against small scratches but a buffing wheel and polishing compound can get rid of 99% of these I've done chainstays or next cranks where I have a lot of heel rub but otherwise I'll polish out my little trail mistakes.
