New & Interesting Bike Campenaerts

The only memory I have of them is sitting on the side of the road on a warm December day waiting for a ride.

[Crustradamus]

I think I sent those tires to @JUGE_FREDD

[BicyclePears]

hmm probably not gonna post this one to IG.

A+ Ian Curtis Easter egg.

The only Hutchinson tires I’ve ever owned were a pair of those early tubeless ones and yeah, they were by far the hardest tires to mount I’ve ever encountered. I got a slash in the sidewall of one (on my first ride ) and had to cut the beads with wirecutters to remove it.

I shooped this back in 2019

these days I’d go right for oat milk

Is there something industrial with walnuts? I know walnut shells are used in media blasting too

love will tear our sidewalls apart

[cheese]

I think it’s just an abundant byproduct that is robust/hard unlike peanut shells. wonder if there’s an industrial use for pistachio hulls

…c UST rims, tubeless tires (Panaracer Fire FR 26x2.4), and zero sealant. Set up totally tubeless, just like an automobile tire.It worked OK but not perfect, would occasionally burp on real big hits(but would re-seat and not lose all the air, just some). TBH I should have tried something other than Panaracer tires, but ended up just adding sealant like everyone else once that started getting popular.

I just retired an old Easton mtb wheel like this. I’d still be running it if the rim wasn’t so narrow.

@jimmythefly

Did anyone other than me ever use a true tubeless system? I mean Mavic UST rims, tubeless tires (Panaracer Fire FR 26x2.4), and zero sealant. Set up totally tubeless, just like an automobile tire.

I had some gen-u-ine Mavic UST MTB wheels for a while. Cartoonishly narrow by modern MTB standards, though - IIRC it was a mismatched pair with an i19 front and i17 rear. I didn’t run without sealant for long. They set up nice in the garage, but in goathead central sealant is really useful…

@stumphumper

Why don’t they do this anymore? Is it a combination of manufacturing costs and reliability?

You need a solid rim bed without spoke holes on the inside, which either means it’s a pain to install normal nipples (slide 'em in from the valve hole… somehow), or a completely proprietary spoke/nipple system. Those mavic wheels had unthreaded spokes, and the nipples threaded into the rim.

You also need tires that are completely airtight. That means a sidewall that’s heavy, thick, and extremely-un-supple compared to pretty much any bike tire you’ve ever ridden.

@adem

slide 'em in from the valve hole… somehow

Pretty sure LB has a video on this. It involves a small section of spoke and a magnet. One can order their carbon rims without spoke holes. No tape required.

[BEEutiful_Wednesday_DDS]

i did that with my light bicycle wheels. they shipped them with a spoke rattling around in the rim! my friend who built my bike said it wasn’t too hard to get it out with a magnet

[Crustradamus]

you mean a nipple?

[BEEutiful_Wednesday_DDS]

sorry yes a nipple
would be impressive if they’d gotten a whole spoke into the rim

[Jacobell]

How are yall getting aluminum or brass nipples to stick to a magnet

[yonderboy]

A short bit of spoke threaded in is my guess. That would also help orient the right end of the nipple.

[cheese]

so for each nipple you have to thread the helper spoke bit in, drop it thru the valve hole, guide it into place with a magnet, then carefully unthread the helper and install the spoke? what a pita

[Crustradamus]

Yeah but in practice I never had to do this on my ust rims. Like maybe one time?

[jame5on]

How do you even get a wrench on the nipple without pushing it through?
