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...

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...

„Radial“ as used in the bike tire industry is already a spectrum of tread angles. If it was used as it should be, radial would only mean one angle, which is exactly radial to the wheel center. But it‘s the bike industry that likes to not give any fuck. Just use the so called diagonal tires, which are exactly what...

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

I believe that plan was scrapped early this year.

Exactly. If you look at the newmen wheels of Hartenstern that have adaptable spoke flange widths for example, he uses a smaller width than possible reducing the spoke angle and making the wheel flexier. Since we only speak about 32“ wheels in the front for gravity disciplines, I also do not think we need wider hub spacing. For the few...

So, going to ask this question fully understanding the debates and tech here... So everyone is saying 32" will NEED new/wider hub spacing, especially for DH. WHY? Most companies are designing asymetric rims. spoke tensions are even. now, on top of that, commencal is running 32h rear 28h front. so going down in spoke count. AND most teams are running LESS spoke tension to get better traction (and in turn INCREASE wheel flex). So.... if you take that into account, I see no need to run wider flanges on a 32h asymmetric rim at full tension. Also... most of us...

Miss those days. Enduro was the hottest shit, clothes were semi baggy and not skin tight, no ebikes… ah yes, beautiful times.

IIRC he relieved (i.e. dremeled out) the arch of a 27.5" fork to cram a 29er in there and then raced it at Fort William so this seems reasonable compared to that...

I've settled on this. TC radial soft/Romy Race Pro rear. Outside of the wet season in the PNW I've decided I prefer standard casings on the rear (burp less, break free a bit easier, and roll faster).

I would probably just use a radial in the front and a regular casing in the rear if rolling resistance is of any significance

I don't like the things Sram appear to have learned from the UDH launch and adoption. Again, they're trying to be Apple, just waiting for the EU to knock them down a peg haha.
