This is the customer SRAM is talking about when they say the DB8 is intended "for riders who prefer to set and forget." Not you or me. Having worked in a commuter shop, you can't imagine the levels of neglect the average commuter bike sees. Preemptively re-bleeding your brakes every year is not on the radar for most e-bike commuters.

I was looking for a better photo with a real commuter wearing the full head-to-toe yellow crab fishing rain gear and the full forehead gaper gap with their helmet hanging off the back of their head, but this stock photo was the best I could do this morning. Sorry.

Nope, you use trackers, and a (metric) shit ton of externally hosted javascript, which takes ages to load.

Is Commencal already selling the updated RockShox Super Deluxe Rear Shock or am I wrong? 🤔 To be fair, delivery date for a Large-sized bike is Aug 22.

Aug 22nd is long after the embargo is lifted. So yes, by the time they're in customer's hands the rear shock will of been public for months. The shock has obviously been 'done' for a while but as always....supply chain.

The specs on that page match the current SD Ultimate, so they may have just had the new shock lying around in the right size. Spec mixups happen all the time for this sort of thing, although in fairness I haven't seen it happen with unreleased products before.

Agreed on the stretching - bring the sizing to 2022 levels. Also can modify the suspension to a highish-pivot design. All else is perfect! Smile
Please don't!!!! Leave it short. This is a freeride bike, it's not supposed to be super long. It should be SHORT. I think high pivot suspension is super sick (I wouldn't complain) but it doesn't have any advantages on big jumps.

New Tr11. I’ve only seen it with 27.5 front and rear. Any one seen it as a 29? Mullet?

There’s a S size for this. Wink

Looks like transition will do away with a proper DH race bike and moving the TR11 to the park/freeride category. They have never even made the switch to 29 wheels (let alone mullet), so that would not be surprising. I definitely see more brands transitioning their dh platform to the "park" category if they don't want to ged rid of them at once, especially since the competition for race bikes is fierce

Not when the size S is too long. 440 reach on size S like the commencals is ridiculous.

With their involvement local dh racing and how much people are digging the spire I assume the 29er dh race bike is coming just maybe not a priority.

The other site has a bike check video up for Hannah's TR11.

Wow, which Commencal is 440 reach on size S? That's huge! I'm currently on a size M frame with 420-430ish reach (not a Commencal) and feel pretty comfortable (with being 1.70m tall).
Banshee could make 4 or 5 sizes to cover more heights, a XS size could have around 400-410 reach, then M could have 440ish, L - 470, XL - 500. They are notorious for listening to their customers and fulfilling their wishes. Smile

Interested in that too as Commencals, at least Metas, aren't particularly long. The XL is about the size of the L of my current bike, like most trail/enduro bikes on the market.

Looking at the Commencal bikes, it seems like the FRS does have a 440mm reach in the small size. Which is maybe a bit odd considering it's their freeride bike and the current gen Supreme has a 425mm reach on the small frame.

Oh yay, we have a new wheel size debate.
Pick a reach and be a....Whistling

I believe that a 475mm reach is ideal, and every other reach is factually inferior. All bow before my infallible personal opinion.

EDIT: I had written it's a proper 6-bar. It's not. Remove the rocker and seatstays and the rear axle path stays the same and completely defined. It's a dual short link, counter rotating 4-bar. The seatstay and the rocker are there to drive the shock. It's actually in the same vein to what Specialized (and Canyon on the Sender) is doing where they have a 4-bar suspension plus a two-link setup to drive the shock a bit more indirectly.

Looking at the video, I can't wait to see the antisquat characteristic. I'm guessing it drops off like a rock off a cliff Smile

Polygon calls it a six-bar design, which is technically true from the point of the shock but not from the wheel. As Primoz said, it's a four-bar with an additional linkage to drive the shock (the two lower links alone control the wheel path and the shock linkage further controls the leverage rate).

Okay - just did a rough sketch of the Polygon and Primoz was definitely right about the anti-squat figures. How steeply they "drop off" seems to depend mostly on the length and orientation of the counter-clockwise lower link (the one that's more vertical), which is really sensitive to changes:

As for the leverage curve, again this is without any published geometry figures and I'm going off of very rough estimates, but there are definitely some interesting changes in shape despite appearing linearly progressive at first glance. It seems pretty similar to the newest crop of Santa Cruz VPP models, with a change in concavity and a 'dive' at the end, again depending a lot on that counter-clockwise link:
