As soon as you lock up all bets are off course. To be honest I’ve never really ridden anything where I found pedal kickback to be annoying beyond when the wheel is locked up. Even going back to back with and without chain. There’s a part of me that actually kind of likes being able to use chain tension to keep it a little higher. Let the cranks rotate backwards a little on landing and the impact is lessened using more travel. Keep feet entirely flat and push through it for more efficiency.
I feel that heavy braking is the largest contributor/least discussed for pedal kick. The situation where you might be locking up the rear brake but still...
I feel that heavy braking is the largest contributor/least discussed for pedal kick. The situation where you might be locking up the rear brake but still using a good amount of travel is the exact situation where you’d really want your suspension performing at its best
@Blake_Motley Agreed, steep chunky stuff is really the only place I notice it.

This comment seems to be a convoluted attempt at drawing parallels between professional bike racing and motorsports, particularly Formula 1, but it’s a jumbled mess of loose associations and misplaced terminology. Let’s break it down brutally:
1. Chain Drive Skepticism: The commenter kicks off with skepticism about recent changes to bike racing due to “chain drive,” but gives no real details or context for what exactly they are skeptical about. It feels like they are grasping at straws, trying to sound knowledgeable while being vague about their actual critique.
2. Motility and Suspension Nonsense: They throw in the term “motility” from motorsports, trying to sound profound by equating it with bike suspension and the manipulation of gravity. This is a bizarre, over-complicated analogy that tries to link the biological term with bike mechanics in a way that doesn’t really make sense or add anything to the argument. It feels like an attempt to sound smart, but ends up being pretentious and confusing.
3. Useless F1 Comparison: The person rambles about how there is no connection between downhill (DH) biking and Formula 1, but goes on to compare them anyway, just to say there’s no point in comparing them. They even mention they’ve never heard anyone call a Formula 1 car “the DH Bicycle of Motorsport”—which is, unsurprisingly, irrelevant because no one in their right mind would make that comparison in the first place. It’s a strawman argument that detracts from any valid point they might have tried to make.
4. Cost Cap Irrelevance: They seem to miss the mark entirely on the concept of cost caps. In motorsport, cost caps are imposed to level the playing field between teams with different budgets. But how this is relevant to UCI or professional biking is left unclear. They seem to want UCI to enforce stricter part regulations, but don’t explain why or how this would improve the sport.
5. Ship of Theseus Tangent: They throw in some pseudo-philosophical garbage about the “Ship of Theseus” to imply that the constant upgrading of parts in biking removes any claim to originality. This is an overblown and irrelevant philosophical detour that doesn’t help their argument—whatever it even is at this point.
6. Mass Dampers and Renault’s Aero Advantage: They attempt to end on a high note by throwing in technical jargon about “mass dampers,” likening them to a decade-old strategy used by Renault in F1 to reduce tire rebound. The implication here is that people relying on mass dampers in biking are compensating for poor skills. But this comparison feels forced and unclear, as the two sports have very different engineering challenges.
In conclusion, the comment is an incoherent mess. The author tries to blend unrelated concepts from motorsport and biking to sound insightful, but instead they come across as someone with surface-level knowledge throwing around technical terms to mask the lack of a coherent point. It’s a hodgepodge of overreaching analogies and poorly articulated frustration that ultimately says very little.

I just hope one day we as a community will stop trying to compare DH or any form of bike racing to motorsports. Now if you'll excuse me, I'm going to go and try to figure out how to make high pivot moto suspension for ultimate enduro prowess.
I'll just use a jack shaft and an extra chain with 1 to 1 cogs. Easy easy.

The more, the merrier! Why limit yourself with a 10t when you can go 9t?!?! This way people can go even lower on the chainring and still have a good-enough gear ratio for high speeds, together with a GS-derailluer for better clearance (as those SGS fuckers are too damn long!!!).

Arent most suspension designs optimized around a 32t chainring? Thats why it seems odd to me they are going that route

Looking forward to quoting this post when it drops.
I've been wrong before and won't lose sleep over it.
But if that's how you get your boners then you enjoy it.
Shimano are more stubborn than I am and we'd have seen a production carbon crank (not an LE from 10 years ago) on their road groupsets already if there was one coming to mtb. And it being KTM suggests its just errors on their spec sheets which is super common across all brands.
For example a year or so ago Specialized had to give away a load of 700watt batteries with Levo sales because they were delivered with 500 when the spec stated 700 (in the UK).

Even so, there are certain things we know with Shimano.
They will not be doing a carbon crank.
They will not be doing 1 9t high gear on their cassettes. They don't even offer 10t to the roadies because of the inefficiencies and slippage.
A couple of days ago I Heard the crazyest thing, that shimano is about to drop a 1x ROAD groupset. Hey, maybe they are caling GRX a road groupset (it is) maybe they have something else...

Shimano has experience with 9t cogs. Shimano Capreo cassettes back in the 2010s offered that option. I ran it for a while and had fine luck though that was on a DH bike.
I wonder if the cranks are carbon or if the ring is carbon... CRANKSET Shimano XTR M9200-12 Carbon 32T makes me think the ring is carbon. If it were phrased CRANKSET Shimano XTR Carbon M9200-12 32T my mind would lean toward crank. Complete speculation.
@Blake_Motley Agreed, steep chunky stuff is really the only place I notice it.

taking all recent discussion into account, I'm thinking this with an ochain will be my next ride.
And an e13 Sidekick hub for safety purposes.
Their rear suspension design must be horrible to warrant such a design to combat pedal kickback. Cant blame the owner. 1000 iq design.
Back to tech rumors!
An interesting drivetrain on the KTMs!
Looks like it’s wireless and the derailleur seems very close to the rear triangle…
Eleven speed linkglide too
Edit: Here's one that isn't blurred out, not that you see very much more.
Edit x2: oh...
This one is TRP E.A.S.I. A12 as pictured thiugh
There's also this in the regular bike catalog.
The text which has had a filter applied, when copied, spits out this:
R.DERAILL. Shimano XTR Di2 M9250-12 GS shadow+
SHIFTLEV. Shimano XTR Di2 M9250
CRANKSET Shimano XTR M9200-12 Carbon 32T
BOTTOM BR. Shimano MT900 pressfit PA29 MTB
SPROCKET Shimano XTR M9200-12 / 9-45
CHAIN Shimano M9100-12
So that's Shimano's first(?) carbon cranks confirmed?
And the brake name is in full view, the new protos we've seen aren't saint? M9220 seems it would be the 4 piston variant.
Sorry Shimano, but there's more:
Shimano Deore XT Di2 M8250-12 GS shadow+
Shimano Deore XT Di2 M8250
Shimano Deore XT M8200-12 30T
Shimano MT800 pressfit MTB
Shimano Deore XT M8200-12 / 9-45
Shimano M8100-12
And M8200 brakes. So at least XTR and XT will be moving to the new lever shape?
Still 12s, Carbon cranks (at least in xtr trim), and they don't look like direct mount derailleurs.
9-45t seems like an odd choice, arent 10t sprockets inefficient enough already?
The source of the pics?
9t is lighter though.
The carbon crank is a Race Face.
Is this a joke? I don't get the point of this.

Clearly not.
Download the catalog yourself and check.

Can you give a link to the catalog, pls?

Ah, I was looking at the ebike which has Era cranks in the spec list too.
Apparently Shimano made a limited edition Dura Ace crankset in carbon in 2010
Even so, there are certain things we know with Shimano.
They will not be doing a carbon crank.
They will not be doing 1 9t high gear on their cassettes. They don't even offer 10t to the roadies because of the inefficiencies and slippage.

That’s no surprise as GRX has been 1x for a long time now

New Sentinel tomorrow, not sure how much is changing, but in-frame storage will be there. There may also be another model, potentially the Scout?
