That is just a video of another youtube hack hiding behind a mask and showing nothing but pictures that we have all already seen.

Garbaruk wheels are already on their website, not sure if it's visible globally: https://www.garbaruk.com/wheels-parts.htm

But one of them doesn’t strip paint, ruin rubber durometer, or make certain plastics brittle.

Looks like the XTR cranks are going back to the old pinch two bolt system again...

The whole gearbox/belt moment right now is solely due to a massive decline in sponsorship of the traditional bike industry. Gates has been huge enough for decades to make their pitch… Shimano and Sram clearly aren’t capitalized well enough to fight them anymore, due to poor pandemic vision and blowing so much money on useless electronics, but the science on belts v chains is pretty clear. Belts suck for the low power applications we see in cycling, and they are super duper draggy, and generally horrible to live with. Anyone who has ever worked on any belt driven bicycle will...

I used to ride moto with an engineer that worked on gearboxes for a major bike manufacturer. At that time, I had just begun mountain biking and didn't pay much attention to all of the tech. But I remember him telling me that although there were many real advantages to gearboxes, it simply wasn't possible to improve the efficiency to cassette like levels as gearboxes, by design, would always have more friction as a consequence of the gears meshing, turning clusters, oil, extra bearings and seals. I'm sure some additional optimization will occur in time but to make a gearbox...

Agree. While I love the idea of ditching the derailleur, gearbox/belt driven drivetrains are measurably less efficient (even when accounting for a chain drive that isn't perfectly clean). This isn't up for debate, it's a fact.

Have you ever held a belt, and flexed it? Even a car engine belt? Belts absolutely have more friction than a chain, it's not even close really. I can't speak for every locale, but I could ride my waxed chains with no maintenance at all in my dry dusty location for 100+ miles with zero change in friction or performance.

In general the comments about gearboxes themselves get comments about inefficiencies. Whichever way you spin it, there are more bearings and seals involved with a gearbox plus a plethora of gear pairs (either loaded or unloaded) which all add to additional drag. In the case of Rohloff you have planetary gears (lots and lots of bearings and gears) while Pinion is quite a lot simpler. Still in that case you have a 2-stage geared gearbox, either a 3x3, 3x4 or a 3x6 layout (for 9, 12 or 18 speed variants) where you at least have to support the input, the...

Excellent Machiny !

It's been done. Rocky, Banshee and others have experimented with bushings. They all creaked worse than a rusty shopping cart after a while... or immediately depending how lucky you were.

also worth noting that I think they all write their reviews in German, which is then changed for the international version. So every article is a weird blend of the original reviewer's words translated, and the personal bias and style of the translator/english writer. They also seem to speak in abolutes and exagerations, posisbly for the same reason. Is it really unrideable with a 180mm rear rotor? And if it truly was, does a mere 10% increase by upgrading to a 200mm really transform it to the best bike in test? That aside, I appreciate the way that in general...

Uhm actually Shimano Dura-Ace Track 7700 launched in 1996 is the longest running unchanged shimano gruppo. /nerd And yeah most spokes versions are 20+ years old. D-light was 2010 and CX-Ray was 1997 for Sapim.

Ever so slight off-topic: My new bike came with adjustable head angle via headset cup, sounded great! But it also comes with headset routing, luckily not the worst implementation and can mostly be ignored. Except of course if you would like to rotate those fancy headset cups, suddenly I need to take out all my cables and disconnect my brake lever. Maybe there is a fancy tool and procedure that doesn't require dismantling all my components, but it certainly seems like those "convenient" headset cups are never realistically getting flipped.
