Kate Courtney is in Brazil already, posted a ride 31/3 with a pic of what I guess is her regular BC40 with red SIDs. 
Yesterday 1/4 posted a ride called new bike day, she’s Called the bike BC40 sparkle, can only see that it’s got purple-ish forks; and has otherwise kept the bike hidden. 
Possibly new, possibly just a custom paint job, possibly new rockshox stuff about to be revealed?

It could be a new bike; she posted a pic from Allied HQ w/ a frame in the stand that was blacked out but you could see a chainstay pivot and afaik Allied doesn't have a crab-link bike.

My guess is just new paint on a BC40 though...

New reverb goes well past 200mm. Seen 3 out in the wild.

I heard a rumor that this new ebike from Specialized can toggle between class 1 and class 3. If true, this blatant disregard for land and recreation managers from one of the United States' biggest sellers is pretty sh*tty.

Yea, new paint job. She was picking out the color in an Instagram post from a couple weeks ago when she was at HQ.

How are they printing 7075? Is it SLM?

Seeing the new Propain, anyone heard about the new TQ motor? Hoping it’s the same mounting and electrical connections and can be a drop-in upgrade for the HPR50. But I’m probably dreamin’

Rumor has it there will be a software update bumping the existing TQ motor up to 60nm before releasing a new motor for the MY26 bikes

Can nobody else get it or can nobody else afford it?


Those processes aren’t cheap.

The feed stock, which is the powder the laser sintering machine melts. It's not commercially available as far as I can tell, but you can buy 6061 if you have access to a machine. I'm willing to bet Atherton will be one of the first customers of the 7A77 feed stock when you can buy it, as it makes the process of making lugs a lot less wasteful.

I can't speak to the actual availability of this either but I'm sure there's even more people working on it.

So reviewers seem to love the Trek Slash ebike, but this norco is a 4 bar high pivot with a full sized motor and oversized battery- why would anyone ever choose the Trek over this?

Just because a bike looks like another one doesn’t mean it will perform equivalently. Think about all the different crab bikes and how differently they perform based on tiny kinematic differences. Brian Cahal recently revied the previous gen of the Norco in an ebike shootout and placed it dead last. Meanwhile, as you say, the Slash+ reviews well.

I bet this new Norco rides really well. 

But that aside, thanks what I hate about ebikes- suspension no longer matters, geometry, compliance, none of it matters anymore. The only thing that really matters is the powertrain and the brakes. People fret over things like the quality of the display, whether you can add overdrive to your older motor via a firmware update, etc rather than how the bike rides. Crappy climbing geometry doesn't matter since you can pedal seated with  the dropper down. Descending geometry is less critical because the much lower CoG a motor+battery gives you makes up for it. I have 0 desire to test, tune, and obsess over suspension settings on my ebike. I barely even worry about tire pressure on it. 

This is probably just grumpy old man syndrome, but half the fun of mountain biking was art. Tuning things. Squeezing every single bit of engineering that you can out of a simple double diamond shape in a completely human powered, analog system, to the point that we worry about lateral vs torsional flex in chainstays and freaking O-Chain even exists.

 Who cares about any of that in the Age of the Ebike.

I can confirm this is true. So disappointing.

Class 1 & 3 are the same, but with 1 having a top speed of 20mph and 3 being 28mph. I run out of assist (15.5mph) before I run out of gears, I'd love assist up to 20 or even 28. Why is this disregarding land and recreation managers exactly?

I would tell you to move to the US to enjoy 20mph at the top speed but that's terrible advice these days.

The class 1 and 3 comment was made on April 1st, sooooo I'll believe it when I see it. Also, using all throttle on a 840 battery won't get you that far when Surrons have over 3100wh.

California and the west coast has long been known for having trail access issues. The implementation of e-bikes have increasingly complicated matters in recent years. Our trail advocacy organizations have fought long and hard for more access by building relationships and trust with land owners. Specialized had long been a big proponent of trail access with programs such as Soil Searching until they recently axed the program due to budget cuts. Now allowing e-mountain bikes to go 28mph on our local trail networks will lose the trust of current partners and kill the possibility of opening up new land to mountain bike access. Specialized know this better than anyone with their HQ being located within an hour of Santa Cruz and Marin County, area's where you often see bumper stickers that say, "mountain biking is not a crime"

Cool bike, but Pivot and Santa Cruz are shooting themselves in the foot by only producing Enduro and DH bikes in Carbon Fiber. Most people don't want to baby a long travel rig everywhere they go, they just want to ride it. Go ahead and down vote this post, I don't care.

What do you mean baby a long travel rig? Have you seen what material gravity race bikes have been made from for the last........10 years? I've seen more catastrophically broken alloy bikes in that time, and Pivot/Santa Cruz customers just plain don't want Aluminium anyway

I'm not talking about catastrophic failure. Carbon is kind of pain in the butt long term esthetically IMO, and it eventually looks really hagard once enough paint is chipped or worn. An A.L. frame you can just take all the paint off and go raw if the paint gets too bad. I feel like people with carbon bikes always go out of their way to make sure it's not rubbing up on anything, ect. I can deal with that special treatment for short travel bikes, but it kind of gets old and feels weird  doing it for a burly long travel bike. I don't mind having a weaker, heavier bike if it's a lot easier to live with, I'm not a pro rider so I don't need to ride the same bike a pro does.

I expect you'd also need an inert atmosphere to produce and handle the powder, or some method of pre-process surface activation.

Nothing screams “claptrap” quite like a stripped-raw production bike that was covered in logos when it left the showroom floor 6 years prior.

And if you’re chipping so much paint off of a bike that it looks haggard due to its paint long before the components become outdated enough for those to be the sore thumb sticking out, maybe it’s a personal problem…

It's probably a Cali-Centric problem, because they put 1/4"-1/2" granite aggregate on all the fire roads around here. You get rock chips from CLIMBS around here if you're not a total squid.

And if you have a problem with a raw aluminum mtb frame, that sounds like a very serious personal problem. You should probably seek professional help with that one🫡
