political posts and responses deleted. take them to " off the bike"

we were talking on our ride last night about avinox, and a couple well placed industry friends was saying that there's a real feeling around that they're about to devour the industry and in particular (SRAM/Shimano/Bosch/etc) as a whole given how much engineering resourcing they're putting into the whole thing (Amflow, Avinox, etc). Granted I'm deaf in one year so hearing the fine points of a conversation at speed can be challenging, but they were saying they have a many many hundreds or thousands of engineers working on the motors, batteries, frames, complete bikes and all the brands playing me...

I feel bad already about cluttering tech rumors with a politics post. Lets leave it here and I'll let someone make/revive a politics thread if they want to bitch more. In terms of thermoplastic vs epoxy carbon and the repair of frames, are carbon repairers able to work with thermoplastic? There are two carbon repairers in my city that do excellent work on bikes. All fairly affordable and straightforward. What happens if I approach them with a broken thermoplastic carbon frame? Ignoring theoretical repairability, is it currently practical/possible to fix?

Also agree! The order is Reduce, Reuse, Recycle for a reason.

Double upvote.

One thing missing here is the fact that with the proliferation of composite know how, there are more people around able to safely repair a wider range of issues. Rather than pretending we are recycling carbon bikes I’d love to see more frames designed in ways that facilitate repair. Repair is verifiable in a way that recycling is not, it is cost effective for everyone concerned, and it is as close as you’ll get to good for the environment. It probably flows on to other design decisions to ensure repair is viable (like bearing placement, etc etc), but designing bikes...

Assuming you’re asking from a technological, not environmental standpoint . Can we technologically put TPC’s in the bin for the next 25 years? That’s a blade that cuts both ways. Unless high performance polymers like PEEK, PEKK, PAEK, PPS, etc come down significantly in price then TPC’s are probably not going to gain much more traction in our industry. But if we don’t work to develop them then there’s zero chance of them being adopted. Much like fossil fuels thermoset resins are so damn good at what they do replacing them is really hard.

This is a cool bike and I feel like we should be talking more about it in the "MTB Tech Rumors" thread than the environmental impact of thermoplastics and carbon fibre. I love a simple, metal bike that can take a beating and it makes me think of a RAAW Madonna, but with a shorter rear end. At $3400, it's priced right in between the Madonna R ($2900cad) and Madonna 3.2 ($3900)

In short, can the cycling industry put thermoplastics in the bin for 25 years again?

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...

*throwdown

All these aerospace grade components and I still can barely get any air.

Can we get a separate thread for requesting separate threads so it doesn’t clog up this thread?

"To what extent to you agree with the following statements? thermoplastic carbon mountain bikes fit well with the way i go out and come home in my daily life"

Then the tyre would hit the lower crown at full compression. Extending the lowers is the correct way to do it.
