What app did you use? 

Solidworks

Edit: I forced the angle to be 66 degrees, and it seems to line up well with the fork legs, but doesn't appear to line up well with the head tube. The head tube is short, and likely a bit tapered, so this seemed like the right approach.

Those 28-spoke aluminum Easton wheels on Steve's bike had a very, very, very hard and very short life.

Glove box, tool mount under the top tube. 

2 holes in RHS of head tube for presumably dropper and shock lockout* - both unused here on ruth's flight attendant version. Possible hole in the rear chainstay for gear cable but can't really tell on the black frame.

But a good indication that they haven't made it electric only, and no headset routing.

*although as a Brit my only complaint on SC is they don't let you put the rear brake hose in the RHS of the frame. I can dream but I'm not hopeful.

Rear linkage looks slightly different but same basic flex stay and no seat stay bridge arrangement.

I'm going by memory only, but not seeing anything obvious that would suggest it's a new bike. Any insight on what tipped it off or are they really just doing a nearly-identical bike with some geo changes (assuming it is actually the new Blur)?

I don't know for sure, but someone on MTBR posted that size large would have 66 HTA, 75 STA, and adjusted stack and reach. If the HTA number is accurate, that's a pretty massive change - from 68.3. That's close to the Tallboy. 

Keep in mind that the 68.3 HTA was only for the xc race version with a 100mm fork, the HTA on the Trail with a 120mm fork is 67.1 which the new one is a lot closer too

Not rumor or top secret tech (or is it?!), but all this SS talk got me excited...

Fellow Luddites rejoice.  $5 in hardware and proper reuse of a destroyed derailleur:

36010ECB-3BD2-430E-923D-405EF0B34A4DD3174DBB-C223-44E8-92A4-163389F6A622.jpeg?VersionId=HRBA6IQfRvUE2YxU4Bv.1Ddt

 

Keeping it about tech, though, this little contraption really made me want to try the Lal Supre Drive.  I hope the Supre Drive or similar concept shows back up in the future.

I was thinking about doing something just like this for my SS epic evo.  Unfortunately, it doesn’t have iscg mounts.  I was thinking about having something coming off the swing arm pivot but I’m not smart enough to implement it.

So probably a small change on the frame, plus glovebox and extra bolts for accessory mounts. Hopefully it's not heavier than the Blur 4 frame, but it probably is with the added glovebox. Seems weird to add that to a racing bike, but perhaps SC sees it more as a all-around short-travel bike these days.

Thought it was familiar, your memory is working better than mine lol. They've been prototyping for a while, wonder how close to production it is. I also hope this means return of devinci as a real core brand.

All i can confirm here is that it does not look like someone took a chainsaw to it, but they have not taken a spartan approch to the design. I think it's going to create a big bang when it drops.

To keep on topic, a rep claimed a Wilson replacement is the most frequently asked about and that their 40th anniversary is an important one.

For what it's worth - here's Google's AI snippet asking about belt CVT efficiency:

Belt-driven CVTs are 80% to 88% efficient in cars, and 70% to 75% efficient in scooters. They are less efficient than traditional manual transmissions (which hit 97%) because they rely on sliding friction to transfer power. However, their ability to keep the engine at its most optimal power zone balances out these losses. 

Belt driven CVT is not the same thing as E-CVT. 

E-CVT uses planetary gears, no belt. 

No ebike company would design a belt driven CVT. It doesn’t make sense for a PEV. They will all be E-CVT.

https://www.oneupcomponents.com/products/rear-hub-157x12

Another nail in the coffin for 157mm rear ends.

So, if we consider:

  1. Transmission drivetrains on super sale
  2. New XD slim driver released that fits low range cassettes
  3. Everyone on your local trails is riding (or seeking to ride) a 1300-1500W eMTB and chewing up their drivetrain in a few hours

Do we conclude that SRAM has a new, e-bike specific, low range drivetrain on the horizon?

Feels like a safe bet as well as lower priced DH options.

I can’t imagine a new driver was introduced only for 148mm DH bikes (there’s only a few) that want to use a 157mm hub.

No. Just don't need that much freehub on DH bikes. Simple as. 

OneUp is first I have seen claiming the benefits of using a 157 hub in a 148 frame with the slim. And Shimano could be cutting down the 10s dh, which does seem quite silly comparatively. You don't need such small steps between gears if you are pointed downhill like that.

Yeah, I posted this a page or two ago. Dual motor eCVTs were a new discovery for me. Absolutely makes sense for ebikes, but no chance at all of "trickle-down" technology to pedal bikes, as a few folks in the thread had hoped for.

Super cool. I'm amazed it took this long for this to show up.

wont the 157 hub with the slim driver (that cuts it to 148 spacing) need specific centering of the rim? Is brake interface same as boost?

Yes, you would need to rebuild the wheel. You can’t just swap the drivers.

Brake spacing on 157 and 148 boost hubs has always been the same I believe.
