And seems like Specialized is running two different brake discs for the Brembos, the Hope-ish looking one with the round holes and another one with a lot bigger cutouts:

There was also this raw alloy shim on the rear axle of Finn Iles' Levo which I have no idea about.

At the back of Finns bike is an adapter for the roller to warm up

They were correct then and they're correct now. We've gone from 1800g fox 36s and 1800g non boost wheel sets on our 26" enduro bikes to 2400g fox 38s and 2200g boost wheel sets on our 29" enduro bikes. Where do we go once we have 32"?

They were too flexy then and they aren't now. It's also offset by the fact frames are lighter now as well. 26" bikes and their wheelsets were so heavy, I compare my set of 26" Sun Ringle Mtx to a set of Stan's flow, the 26" set is heavier, and the rims are still cracked.

Think how much lighter a modern through axle boost hub can be compared to an older quick release hub with chunky axles too. Things are heavier now compared to 5 years ago, sure, but when you compare them to 26" bikes or the first wave of 27.5" bikes they're a whole lot lighter.

Damn can’t imagine spending 100€+ for a rotor and it rusts like that 🙄

That usd fork looks ready to be released

Does anyone have it on good authority that this fork will actually be released 6/24, as previously stated in this thread?

USD fork, USD rotors, what else can we reverse?

About Galfer Sharks, I had a pair that rusted too, no other rotors I've owned ever did 🤷‍♂️

Whole lot lighter? My wife's Mojo HD disagrees. (that bike will never die, unlike it's bearings)

The hub width thing isn't something I considered at first until talking to some fork manufacturers at the Taipei Show this year. The consensus seemed to be that 110mm wasn't wide enough, but no clear idea on what the ideal width would be. 

It sill seems crazy to me, I'm of a similar mind to @kperras on this whole thing, but it's happening and the ones really pushing for it aren't necessarily the long leg gang. 

Our 32x2.40 Aspen is 12% heavier than our 29x2.40 Aspen in the same construction. Now think about everything else that is going to get heavier too: larger rim, longer spokes, wider hub, wider axle, longer fork, etc...

20% heavier wheels is like 2 or 3 pounds. For tall riders that is absolutely negligible. It's a small market, and maybe too small to be viable, but if short people have 24", 26", and 27.5" wheel options, I don't see the harm in letting people over 6'4" have an additional choice. I'm 6'7" and people are constantly asking me if my bikes are 27.5 since the wheels look comically undersized versus the frame. I'd happily try a little extra weight to see if a larger wheel diameter helps compensate for my higher center of gravity.

I’m fairly certain that’s the new air drop that is about to drop. Rocker link and headtube junction match. You can practically see the airdrop badge under the tape.

The covered head badge looks like the Chromag. Could possibly be their new 170/160 alloy enduro bike. The resemblance to RAAW bikes is uncanny.

HEY HEY HEY!
Stop the Presses!
Have you guys heard that Industry Nine bought WAO? 


jeez. I have not seen such a lame media blitz since 5DEV made the revolutionary discovery that cranks can be shorter than 175mm


But seriously, I wish the boys at WAO all the best.

I'm only 6'3", but I could easily see that a 32/29 mullet being a game changer for people 6'1" and above.  I find that most people my height have a bit more of a take-it or leave-it approach to a mixed wheel setup.  It has always made me wonder if really what is going on is that the additional leverage and inseam length means that tall people can man handle a 29r rear wheel the same way a shorter person can handle a 27.5.  If I assume that's true, it means to me, that the giant's amongst us, would be even happier with a larger front wheel then what is available now matched with a 29r rear wheel.  

On that subject, I feel like a 32/29 mullet xc bike might be an interesting proposition.  A heavier front tire/wheel isn't anywhere as impactful as a heavier drive tire/wheel.  

That being said, I want to go back into the wheelsize war era of mountain biking about as much as I desire going to the dentist.  What's old is new again, pick your favorite wheel/tire size and be a dick about it.

I was always curious how such a heavy bike could be used to tune suspension, since I would imagine the suspension behaviour is dependent in some ways on weight.

 

Unless there is some kind of scaling that can be done, which wouldn't surprise me since physics is the closest thing to magic

Why are you talking about QR and old shitty Ringle stuff? That has nothing to do with... anything really. Fox 36s and everything else used a 20mm thru axle, and most frames were 142 thru. Ringle stuff was always shit and cracky. I did wildly stupid things to my 1750g Mavic wheelset, absolutely beat it to shit, and I only retired it because I bought a 27.5 bike.

https://www.vitalmtb.com/community/matf1,19896/setup,33576?keyword=SB66C&frame_brands=&sort_by=changed&cat=Bike%2BCheck

There's a 160mm enduro bike with alloy rims and a 180mm fork. 13.6kg. It wasn't uncommon at all to build them up under 13kg. What's an SB160 weigh with an equivalent build? 15.5-16kg? 

Don't get me wrong, I have no problem with heavy bikes, my trail bike is 17kg and my gravel bike has a pike on it. but there's no argument that 29" wheels have made our bikes significantly heavier and that we've needed new standards to make them ride well, and you'd be stupid to think that we can just slot 32" into our current designs/tech and expect it to work well.

 

I don't think 32"/29" mullet will do well in XC at all. Most of the rolling resistance comes from the rear, so you miss out on a lot of the advantage, and most XC setups have tiny head tubes and drop stems to get the front end lower already, so height is going to be a problem for most. I think it'll see acceptance by XL riders on full 32" who want to just put their head down and make power, roadie style, and don't want to have to bother with things like riding the trail. Maximum clearance, maximum rollover, maximum grip, spin to win. Everyone else will be on 29". I look forward to being wrong because I know fuck all about XC.

You're right. I probably shouldn't be speaking on bikes that are before my time. Also, I'm not on the 32" train, it would definitely disrupt the existing standards.

QR was very much a thing up to about 2010 when 15 and 12 mm through axles became more widespread. Shimano and Fox introduced the 15 mm front axle in 2008 and Syntace's X12 was introduced in 2010 for 2011 bikes. Before that it was QR, bolt-on or maybe 135x12 in the rear and QR or 20 mm in the front.

We tested Crankbrothers new Synthesis Enduro Alloy 2.0 wheels that launched today and were super impressed by how stout and durable they were. Our tester Mikey has broken every wheel I've ever seen him ride, and these wheels have made it just about 4 months completely unscathed. Which honestly speaks more to their durability than Commencal/Muc-Off racing with them 😂  

They're sold as individual wheels, but complete sets retail for $700 (CB hubs) and $900 (i9 hubs), and the rims carry a lifetime warranty—a first for Crankbrothers on alloy rims. There is also a DH/e-MTB model.

Those frames were made of paper, that's why that bike weighed 30lbs, I've seen more of those frames cracked on the downtube at the BB junction than any other frame ever, Yeti was good with the warranty but that was by far from a "burly" bike. My 2014 slash weights 30lbs, thankfully its carbon, as its been repaired more times than I would like to admit. That Talas fork was a boat anchor, with the tapered steerer it weighed 2.9kg, my 180mm RFX38m.2 weights 2.3kg, lighter than the straight steerer 36 talas which was 2.45kg. Bikes from that era either pedaled great and otherwise rode like hot garbage or vise versa. Anyone really hucking "enduro" bikes back then, and I mean like the kids sending felton, SC and P.O. and not breaking everything every other ride, were riding 45+ lb bricks, I tried, I ended up with carbon splinters...

My 2014 slash weights 30lbs, thankfully its carbon, as its been repaired more times than I would like to admit. That Talas fork was a boat anchor, with the tapered steerer it weighed 2.9kg, my 180mm RFX38m.2 weights 2.3kg, lighter than the straight steerer 36 talas which was 2.45kg. Bikes from that era either pedaled great and otherwise rode like hot garbage or vise versa. Anyone really hucking "enduro" bikes back then, and I mean like the kids sending felton, SC and P.O. and not breaking everything every other ride, were riding 45+ lb bricks, I tried, I ended up with carbon splinters...

Besides wheel size, the fact that we as riders keep pushing the limits of the bikes also means frames and components have to get beefier... Which all adds weight..

Amazing how there are so many people who come to a tech and innovation thread to complain that bikes have changed in 15 years. “WHAT? ANOTHER INNOVATION? HELL NO NOT ON MY WATCH, BROTHER.” “WHAT THE HECK? BIEKS ARE GETTIN EVEN MORE CAPABLE AND FUN TO RIDE? I NEED TO POST MY OPPOSITION TO THIS MALARKEY.”


Edit to add: it’s also a really wild take to say that bikes peaked in 2012. I personally think it’s a wild take to say that bikes are peak right now. They just keep getting better!

Who makes this 20mm to 15mm adapter and is it Boxxer specific or do they make them for other forks?

Freaky Nuts also makes them.  I'm considering put a Fox 40 on my A.170 for park use this season and ordered one of these for the conversion if I go that way.  The materials seem to be of high quality.  Compatible with Boxxer, Fox 40 and Rux38.

I’m going the opposite direction and putting a 38 on my ebike which currently has a 40 on it. I have a lot of really tight 180 switchbacks on my local trails and it’s hard to make some of them with the limited turning radius of a dual crown. But I’d like to be able to use the same front wheel, it’s a Tune 20 x 110 hub. I checked Tune’s website but I can’t find any adapters for my application. Anyone know if anyone makes a conversion kit for 20 to 15?

There are loads of solutions such as this on eBay.

The issue is the endcap of 20x110 mm hub won't fit into standard boost 15 fork and this kind of adapter does nothing to fix that. Any decent machinist will turn you needed end caps on the lathe though for maybe 30bucks if you bring your own material.

Aah, probably why it's best to leave it to others for these things, I didn't think about the end caps.
