I found that smaller diameter grips work better in almost every way - although thicker grips are cushier, I find myself gripping on them harder because they feel vague; moreover, I can hold on more securely and relaxedly on thinner grips since I can wrap more of my hand around the bar. That said, grips are pretty cheap so you...

Long time lurker, first time poster here. For some background I’m an aerospace composites engineer and spent several years in Advanced Product Development with an emphasis on environmentally friendly materials. There’s so much to get into on this topic and if folks are interested I’d love to start a dedicated thread on materials and environmental impacts. The TLDR is, carbon fiber as a green product on its own is a fallacy. The raw fiber production may result in a certain level of carbon sequestering, but the process is still so energy intensive I wouldn’t call it an environmental positive. As...

I used to struggle with hand pain for a long time; over my many attempts to find a solution for my problems, I believe I've arrived at a pretty good setup. For one, I don't wear gloves anymore. I can't say I've had my gloves bunch up, but I did find that I gripped harder when I wore them, which...

When buying gloves buy something that feels a bit too tight when you try them on in the shop as they stretch out to fit your hand and not bunch up.

You are already riding bikes with aerospace carbon fiber. The actual fiber is the same as what's used in aerospace. Example: Toray T1100 is the world's strongest fiber and used in both bikes and aero. T1200 coming and will be 10% stronger. What's different is mainly the resin and the process of making the bike. Note I could argue some of the bike parts I've seen are actually more complex and high performance than many aerospace manufacturers would/could make. It's impressive how far we've come in this industry.

You looking specifically at that pic? If so, that’s not his bike in the pic. He’s just unloading it. In other pics from the same day, he’s on his usual bike. But to confirm- levers are not flat enough, bars are rolled back, no stem spacers for that high stack, old fork, no ochain, diff tire set up. Sorry I rambled. Dif bike haha Now in regard to ochain… I’m definitely curious about that! He was the main guy prototyping higher/different degrees… and now it’s Sram. So it’ll be interesting to see how that’ll play out

New Supernaught development - Dred E with a Boxxer, custom link and what looks to be a bb conversion where the motor was?

What thermoplastics allow us to melt away the matrix to be left with just the fibres. I guess you could either chop those to be a filler or recycle them (make new fibres), but you are for sure not picking up a cloth from the bunch of fibres and reusing it. As I see it (without being in the know) it's mostly component separation that's the benefit here vs. resin matrix materials than the "reuse" type recycling. Reusing old polymers is frowned upon anyway outside non ctiritcal applications as you don't know the state the polymer is in. These are...

It had to have been, apparently they were working with REIN4CED which folded.

Are thermoplastics commercially viable though? GG and Forge + Bond are both in the toilet. Did anyone make it work?
