SRAM Eagle™ | German Engineered

SRAM Eagle™ | German Engineered
The sport of mountain biking has its epicenters of excellence — places where the word ‘progression’ really means something. The product engineering of mountain biking also has its hotspots. And few have a more interesting history and legacy than Schweinfurt, Germany.

Located near-perfectly in the center of Germany, innovators from Schweinfurt are responsible for the first precision ball-bearing, the first ball-bearing hub, the first freewheel and, now, SRAM Eagle™, the SRAM 1x™ drivetrain that continues to redefine mountain bike drivetrain capability.

Mystery of Prince Rupert’s Drop at 130,000 fps – Smarter Every Day 86

Mystery of Prince Rupert’s Drop at 130,000 fps – Smarter Every Day 86

Please help me justify putting this much time and effort into a video by clicking “LIKE” and SHARING this as much as possible. Click the following: Tweet: http://bit.ly/TweetRupert Facebook: http://bit.ly/PrinceRupert Please share with any science blogs or outlets you think would enjoy it.

Videos like this don’t just happen. They require lots of time, and lots of favors from very smart and kind people willing to help me and you learn. PLEASE take a moment and read the following information and support those who supported me.

This is the camera we used for the ultra-high speed shots. It has the “FAST” option.

You absolutely have to check out the stuff Cal Makes. We’re just goofing off in this video, but the guy is some type of glass wizard genius. It would make me happy if you bought something from him and he felt like the audience appreciated all the time he donated to this video. He basically gave me 2 entire nights of his entire shop.

I feel like we’re friends at this point, and he is open to the idea of doing more videos in the future and teach me more about what he knows about glass. Let’s make it worth his time.

I’m a HUGE FAN of the song Gordon wrote for this video. His landlord would really appreciated if you downloaded it so he could make rent this month.

It looks like he’s assembling a new album that I may like more than Mammals:

This video involved about 2 months of research, and me reaching out to several individuals. I would like to thank everyone who took time out of their schedule to contribute to my wacky research. A big thanks to the following people:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
My wife and kids. I’m sorry this took so long and I wasn’t the kind of active father I want to be during the 5 weeks it took to make this.

Dr. Martyn Poliakoff for getting me access to documents which details experiments on the Prince Rupert’s Drop by the Royal Society
http://ift.tt/QtQF2l (behind a pay wall)

Being able to calculate the failure front velocity of a Prince Rupert’s drop is a pretty big deal. For years this was a scientific mystery. High speed camera technology is only recently fast enough to provide data like this. Thanks to Vision Research for letting me use the V1610 to try to unravel this mystery for the public in general.

Rob Kuefner for reaching out to me and offering to convert certain equations into LaTeX format for me.

Dr. Jeff Evans from UAH. A friend and neighbor who just happens to have a PhD and be an expert in fracture mechanics. http://bit.ly/YLezDA Thank you for helping me by pointing me in the right direction in the early stages of my research. It’s time we hangout again.

Brian: thanks for letting me use your green screen and telling me about Orbix in the first place. I stayed up there til about 1 or 2 am two nights in a row acting stupid in front of of the camera all alone. Now that I look back at that footage without the context of this video, it’s all very strange.

Thanks to Loïc Samuel for taking time to make the custom TNT Degradation graphic!

P.S. There was some old guy walking around the track at the park when I was filming me jumping on the bridge railing. I’m pretty sure you kept walking until I was done just to make sure you wouldn’t have to take me to the hospital if I broke my leg. I’ll never meet you again, but I’m grateful for this kind gesture you didn’t know I noticed.

Tweet ideas to me @SmarterYouTube

Instead of saving for my kids’ college, I make videos using the money I would have saved.
The thought is it will help educate the world as a whole, and one day generate enough revenue to pay for their education. Until then if you appreciate what you’ve learned in this video and the effort that went in to it, please SHARE THE VIDEO!

If you REALLY liked it, feel free to pitch a few dollars towards their college fund by clicking here:

How to save 30 watts of drivetrain losses using only your chain! aka Friction Science in 8 steps

How to save 30 watts of drivetrain losses using only your chain! aka Friction Science in 8 steps
Here we examine how serious riders can save 30 or more watts in drivetrain losses by paying attention to their chain alone! In truth you can only “limit losses” and never truely gain watts because every bike loses watts / power in the mechanical parts. If you made all these mistakes we estimate it could cost you 34w. However by paying attention to these 8 steps you could turn -34watts into only -4 watts of losses. This could be very important to timetrialists looking for marginal gains. If you want to look into these drivetrain losses in more detail I recommend: http://ift.tt/28UfNty. Also search velonews for other articles on this topic.

Here are the tips one by one
1:30 Quick clean on the bike (12w)
1:43 Quality manufacturer (5w)
2:07 Chain length (4w)
2:35 Cross-chaining (3w)
3:10 Chain specification (11sp) (2w)
4:32 Chain wear (2w)
5:15 Deep clean off the bike (1w)
6:06 Super lube (4w)

Tokai is open (on weekends). Thanks to all involved. The #mountainbiking trails are looking great and the fun factor is way up there. Serious climb up but what a jol coming down.
