Any news about the next Avinox M2 SL Motor?
X01 cassette, X01 chain, GX cranks with NX steel chainring is GOAT for durability setup.
Deraileurs not so much. Regardless of tier I purchase my derailleur is MAYBE lasting me a season. If I have the same deraileur for an entire season it is going to be clapped out by the end. Not that they are bad products but deraileurs have a hard life. After 3-4 times going to a bike park with an eagle setup the shifting will be giving me issues which is 100% why I own a DH bike now.
The bike park destroys your derailleurs in 3-4 trips? I get years and thousands of miles out of rear derailleurs that are usually still going strong when a crash or an errant stick takes them out. Have you heard of maintenance?
I thumbs upped both posts because I agree with both of you. I don’t know how other people have derailleurs for so long but mine are clapped in a season. I’m wondering if new clutchless derailleurs will hold up better.
I am very rigorous with my maintenance and my shimano's are usally pretty toast after the summer.(i dont ride in the wet).
Sloppy pins etc and starts to get lazy in shifting.
They seem to take a hammering at the bike parks (rarely do I ever hit one on anything)
Madrone Jab FTW. Sloppy pins? Tired clutch? Bent arm? Just service or replace what needs to be refreshed.
What maintenance would possibly prevent sloppy bushings and soft plastic bending? I’ve literally never had a shimano mech last longer than a season, SRAM maybe two seasons.
Derailleur maintenance rumours: for the bushings, a squirt of a good penetrating lubricant from time to time might help. In the case of Shimano it might even keep them working... I once had an XT derailleur bind up completely because of the fine dust around here, but a soak in some light oil got it moving again.
Damn, I haven't heard that yet. I hope those reports are overblown.
I might have to buy another X01 setup to stash for future use. My current one has been great.
Garbaruk cassette for me now (ratios... Shifting performance is worse than original) and rotating 3 X01 chains, I call it forever drivetrain.
As for destroying derailleurs the one that I sold off and is still running, while I had it it did two Megavalanches, an Enduro2 in Les Arcs, a Trans Madeira, four Finale Ligure shutting trips, plus some other local enduro races, shuttling days and trips, etc. I even parked it on a wooden ledge on Petzen about a month before selling and all it needed was to straighten out the hanger to shift perfectly.
The only issue I had with it was that the clutch got very sticky towards the end at some point, but flushing it with isopropyl alcohol fixed that.
I was waiting to see what Transmission will be like before buying a new bike, seeing it (axs only) I was pondering trying out Shimano, but the feel on the shifter is so weird so calmer heads prevailed and I just bought another X01 derailleur and shifter combo and paired it with what I mentioned above.
Should we make a Derailleur Tech Rumors derailment?
...surely Derailleurment
Apparently a new Bulls
Very difficult to tell whether it isn't just one of their existing models to be honest
Oh well, didn't see that they have it on the website by now. My bad.
Looks exactly the same:
Very interested in the JAB, but the rebuild service costs as much as a new derailleur from Shimano. The appeal of the JAB for me is the durability. (and the looks of course) It's the only derailleur out there that looks like it can actually survive the things we put our bikes through.
Have one and so far the derailleur is more rigid and sliiiighlty more crisp/fast than my old xt sgs (Shimano xtr cassette/shifter)
More powerful, more features, quieter, maybe lighter ...
That's actually a clean looking frame IMO. Obviously fk the headset routing though
got a PR today about Release Layer helmet tech. looks really interesting with breakaway panels and a ball bearing system. deets below - www.releaselayer.com

INTRODUCING RLS (RELEASE LAYER SYSTEM) - THE FUTURE OF HELMET TECHNOLOGY THAT REDUCES CONCUSSION RISK
RLS is proven to reduce the risk of concussion by 4x on average compared with conventional helmets
Designed and manufactured by engineers based in East London, UK
Canyon Bicycles will be the first brand to include RLS in their helmets
There are around 55 million* cases of Traumatic Brain Injury (TBI) reported globally each year. This can lead to a wide spectrum of health outcomes, from mild concussions to long term cognitive disabilities.
With the growing increase of e-bike usage alongside the increase of e-bike injuries- (incidence of head trauma from e-bicycle accidents in 2022 was approximately 49x higher than in 2017. A growth rate that outpaced overall e-bicycle injuries).** - it’s never been more important to develop a solution that reduces TBI, not only for e-bike riders, but cyclists, motorcyclists and safety workers.
Introducing RLS (Release Layer System). RLS is a new patented technology that reduces concussion risk by enabling panels on the exterior of a helmet to roll and release upon impact, significantly dissipating rotational force that can cause life-changing brain injuries.
The brain - our most vital organ, and the source of our character, personalities and being - is highly sensitive to rotational motion, which is present in the majority of head impacts and a leading cause of TBIs. RLS is so effective, that in an independent study, RLS was found to reduce the risk of concussion by 4x on average compared with conventional helmets***.
Within the layers of a helmet with RLS technology, RLS panels are connected to a lightweight polycarbonate bearing layer that is designed to activate when a significant impact force has been detected. Upon impact, the technology is designed to work in a matter of milliseconds. The bearings are free to roll in any direction to allow the RLS panel to release, thereby redirecting concussive forces away from the brain.
React: The patented RLS adhesive layer is engineered to react instantaneously to specific impact force, releasing its grip and allowing bearings to roll.
Roll: The RLS Panel is now free to roll on lightweight polycarbonate bearings in any direction, to redirect rotational energy from the brain.
Release: The RLS Panel releases to further dissipate rotational energy, which can help better protect helmet wearers from concussive force.
Helmets with RLS technology are independently tested by experts in the field. And the data speaks for itself. Tests conducted by ICUBE at the University of Strasbourg - a world leading research centre in biomechanics - found that helmets with the Release Layer System reduced Peak Rotational Velocity by an average of 57% - 66% across different impact locations, compared to the same helmets without RLS. This corresponds to a 68% - 86% reduction in the probability of brain injury as estimated by the Abbreviated Injury Scale - Level 2.
Conventional helmets are designed to address linear impact forces, despite the fact that most real-world accidents generate significant rotational forces. Some technologies, such as Mips, aim to mitigate these rotational forces by allowing the helmet to rotate independently from the skull. These technologies, which are generally located on the inside of the helmet, offer a limited range of motion during the critical milliseconds of an impact. RLS addresses rotational motion through the free-release of panels located on the outside of the helmet.
As with many great innovations, this technology was discovered almost by accident, by the founder of RLS, Jamie Cook. Jamie, who was working in the helmet industry as co-founder of HEXR, the 3D printed custom helmet company, noticed that the outer shells of his colleague’s 3D printed helmet released in an accident, and this action was found to significantly reduce rotational forces and the risk of concussion. Jamie and his research team began exploring the most efficient ways of releasing panels which led to the use of small lightweight bearings between the shells.
The first helmet available to consumers with RLS will be the Canyon Deflectr RLS Helmet due for release later this Autumn. Canyon Bicycles, based in Koblenz, Germany have been working closely with the RLS team to build the technology into their new helmet, and as so, the Deflectr Trail helmet is now number 1 on the Virginia Tech helmet ratings (as of 22/9/25).
“RLS is first and foremost designed to protect what makes you, you”, says RLS founder and CEO Jamie Cook. “Your memories, your personality, your loves and hates are all in the most fascinating part of the body - the brain - and RLS has been developed to protect what matters most. We are incredibly excited to launch this technology today, especially with our launch partners at Canyon as we share a passion for safety and disruption technology.”
Over the coming months, RLS will announce further leading brands and partners that will incorporate RLS technology.

#BMXtechRumors - Huffy drops a pro-level bmx frame - the sledgehammer! will a mountain bike be next? (doubtful)
Maybe they'll figure out something to do with Niner? Maybe a Huffy branded DJ frame?
Never thought I'd see reactive armor for the brain... but here we are.
I'm all for brain safety, but I have to wonder about how safe it is for your face to have your helmet literally grenading on impact. Like, what's going to happen if your face hits one of those breakaway plastic panels? That can't be good.
I’d rather cut my face open than be a vegetable
Me too, but I'd also rather take a #3 or #4 ranked helmet and not slice my cheek open or cut my ear off.
I can assure you better plastic panels than a rock to the face.
Not going to lie, if this works as well as they say then I'm buying one immediately, along with a full face if they ever make it. This is incredibly cool tech.
