I have no idea :D. But since the Izzo has a relatively steep seattube angle for a short travel bike I would assume the capra will have a much steeper seattube anlge than the previouse version.

I reckon that the updated version will come with a steeper seat tube angle, a slacker head tube angle and a longer reach + place for a water bottle as already discussed. Curious to see if they stick to the two wheel size options or if they will also offer a version with mixed wheel sizes.

They will most likely also release them as core models (similar to the Jeffsy).

Bit surprised to see that they still do not offer the TUES with mixed wheel sizes.
Hoping they do a mullet... I have a 27.5 Jeffsy, great bike, but a mullet Capra with 63.5-64 HTA (with short offset fork/40mm stem), steeper STA and water bottle would be great.

Wyn isn’t even trying to hide that prototype gt anymore. Release coming soon?

I hope so, my friend is on a xxl and he is 203cm. He rides if not behind top of the rear wheel it would be a good upgrade
Very few bikes are designed in such a way to be OK for 190+ cm riders.

I actually rode the current XXL Capra (might have even been an XL actually) and compared to my ride, it's horrible for pedalling up a hill.

Same colour, same link, etc., and you can see here that the idler height is not that extreme compared to the top of the chainring, while you can see in the wheelie video that the chain is relatively far up from the chainstay, which isn't that usual on modern bikes - chains are usually much closer on idlerless bikes. The same could be true on an idler equipped bike, but the GT has a relatively low chainstay position compared to the idler.

Looking at the thumbnail of wyn wheelie-ing on the new bike, it looks like it might have adjustable chainstay length. It'd be sweet if they make the bike 29 and mullet compatible like the fury.

Anyone seen that wild teaser pic of a YT Tues Boost (possible e-Tues)? Anyone heard rumors or some inside info? Smile

The rocker looks a lot like the current Fury and the back end arrangement too. Not a bad thing I liked my Fury 2019 so a smaller, pedalable version might be nice.

What are we thinking on the next Spesh Enduro? Should be up for a tweak by now!

It’s not even been out for 2 years yet and it currently pretty much up to date so no change for another 18 months - 2 years

The Enduro of course. Seattube-toptube joints cracking, shock tunnel yoke to seat tube area cracking, lots of stones getting caught in the chainstay linkage (above the BB ) and around the shock, causing cracks (the Stumpjumper comes with a much better frame protection equipment to combat that), there have been cases of headset seats cracking, the replacements included Sworks frames replacing Comp spec frames, Fox X2 shocks replacing knocking Super Deluxes, etc.

I don't have personal experience, but I know a few people that do and that follow the topic quite in-depth (in multiple owners groups across the internet).

It might be blown out of proportion, but at first glance it seems quite rampant. And the replacement strategy seems like putting out fires kind of strategy, though it might be connected to stocking issues as well.

I don’t know anyone who has owned a current style specialized enduro that hasn’t cracked it.

You’re scaring me here. Had 21 enduro since September. Guess I better go check it now haha. Where are these common cracks happening?

mine cracked here (top of shock tunnel) after about a year of riding

Good to know guys, I'll be checking these far more carefully when I have one in the stand.

As far as I've been told (and mostly already wrote it), the shock tunnel ad per Robert's photo, seat and top tube joint and I think something around the dropouts? That and use moto foam around the links to prevent stones getting caught in the linkages.

Chainstay and seatstays cracks a lot too

I've got an enduro comp built up. 3000 km in, plenty of pro lines in the WBP, and (too many) crashes. No cracks, but it's well worn. knock on wood.
I've seen the PB threads about cracks, and check the frame once a week. I do know someone who cracked one, and got a replacement from spec in about 10 days.

If anyone is ever wondering how far the bike industry is, as far as technological advancements, here's a good one to put some perspective on currently available bikes. Shimano are working on machine learning and artificial intelligence models for bikes. I'd say this is likely going to be for a commuter-type bike, but they do state this system can control brakes, a dropper, and suspension. So maybe it'll show up on a mountain bike. They're pretty light on the details about these components.

In short, the machine learning model is designed to output an 'assist ratio' to a motor and gearbox so the rider is always in a 'comfort zone' when riding, based on sensed information around the bike. Then, the system will periodically ask you whether you liked the settings or not, and will adjust the machine learning model as you answer questions. Over time, the bike will learn you, and only you, for an optimal ride. Not sure if this is interesting or scary. Either way, here's proof that bike research is far beyond where the public thinks we're at. It's only a matter of time before we have legitimate smart-bikes.

Well with the current state of technology and marketing, a smartbike is the obvious go-to. If you're talking about battery powered bikes, with the battery part meaning either an e-bike or just a LiveValve/AXS/etc. equipped acoustic bike. Which is all fine and dandy, if you like that stuff.

While I'm a massive geek (I have a complete separate, self-setup TrueNAS NAS machine with two additional SBCs running Pi-Hole on my network besides the main workstation and an additional simulation/compute machine waiting for some parts to build it up, all of it mostly for fun, not for profit or anything), I do intend to keep my bike mechanical for the foreseeable future. Which means smart bikes aren't really a factor for me Smile

I get that it might (and probably will) improve bike handling and experience and I'm all for advancements and improvements (hell, I'm riding a 1292 mm wheelbased XL 29er trailbike at 150 mm of travel front and rear, I went fully 'advanced'), but there is also a point to be made to improve your technique instead of improving the technology you put between your legs.
