Guerrilla Gravity's Less Expensive, US-Made Carbon Frame
@raelx: If they're using thermoplastic resins the processing temperature could be as high as 800 F. I work in aerospace, not bikes, so I'm not totally familiar with what they do for bikes. I agree about the fiber discussion, I think he was trying to say they don't use chopped fiber, which is odd. Other companies (Scott off the top of my head) tout the use of T1000.

Guerrilla Gravity's Less Expensive, US-Made Carbon Frame
@skelldify: maybe they poached some know-how from an aerospace company. and they did get a grant from Colorado.

Guerrilla Gravity's Less Expensive, US-Made Carbon Frame
To connect the dots for anyone curious they're using an out of autoclave process with a high toughness thermoplastic resin. Good for them, that's the future of composites where cost matters. Note that 300% tougher (impact resistance if you will) does not mean 300% stronger. Toughness is a resin dominated property, strength is fiber dominated.

7 of the Best Mountain Bike Lights Ridden & Rated
I've been using the Bontrager Pro RT and have been happy with it. The clamp is a bit of a pain to get on a 35mm bar, but is secure once attached. I will probably get another one for a helmet mount.

@Gregorysmithj1: Truck bed paint sounds thick and tough, cracks could easily be hiding under there.

The Creative Process Behind YT's 'Return Of The Goat' Video
I agree. The creepy goat with the third eye really put me off from buying a Jeffsy.

Photo Report: XCC Short Track - Vallnord World Cup 2018
try getting some air with a high seat post and slammed bars, I'd say it takes skill not to crash at the speeds they're going

Review: Giro Empire VR70 Knit Shoe
@mikelevy: I once crashed and got small rocks stuck in my ratchet mechanism. I couldn't get my shoe off without a screwdriver. That made me re-think ratchet straps.

Bike Check: Vlad Dascalu's Protek 29FS - Nove Mesto World Cup XC
A note on the T800: 12k isn't a weave, it's the number of fibers in a tow (bundle of fibers). The checker pattern is from a plain weave.
