The Dusty Dynamics Fluxcutter is an Electromagnetic Fork Damper
Does this use just magnets for suspension control or is it a magnetorheological damper similar to the GM magride systems? I listened to a podcast with the man responsible for the Corvette's ride and handling development through the C6 - he said the magride system could make the car float like a Buick or make the suspension completely locked out with infinite adjustability in between.
Seems like the natural evolution of Flight Attendant/Live Valve. Putting an IR/LIDAR scanner on the head tube could even allow for predictive suspension, like the Mercedes "magic carpet" tech, just like you mentioned Dario

Video: Matthew Fairbrother Rides 500km Around a McDonald’s Drive-Thru
I wonder how much elevation gain he'd get running the high line at a shorter oval like Dover. The drivers say it's a 2 story drop from the turns to the straights, back of the napkin math says...6000ft / 1800m total?

Pinkbike Poll: Which Components Did You Buy In 2025?
@jdejace: I don't like the amount of initial bite or lever feel that I'm getting with 200mm HS2 rotors front/rear and SRAM metallic pads. No contamination, recent bleed.
I find the absolute power of the brakes to be acceptable, but I find that I have to really yank on them to get them to bite and hold. Now that I think about it, I may not be getting enough heat into them during normal riding to get the consistent bite that I want. Maybe I'll try an organic or semi-metallic pad in the spring.

Pinkbike Poll: Which Components Did You Buy In 2025?
@steelpolish: appreciate the response, sounds like the rotors might be overkill for my riding in New England.
If anyone has suggestions for better dry weather pads for Codes (compared to OE SRAM metallic) for a ~190lb rider, I'm all ears

Pinkbike Poll: Which Components Did You Buy In 2025?
@steelpolish: I was considering getting Dominions to replace my Code RSCs but this is an attractive option. How do the Galfer pads & rotors compare to HS2 rotors and SRAM metallic pads?

Pinkbike Poll: Do You Change Tires For Winter Riding?
Hookworms come in 29" for a reason

First Ride: 2026 Norco Revolver 130
I liked the first ride video, really cool to see some of the more technical terrain you guys have out there. Looks like a really fun place to ride a bike like that.

Spotted: Jackson Goldstone on the New Fox 40 Fork
username checks out - been in your position before. I got a Mezzer Pro last year, it's the real deal if you're okay with spending a day or two on your local trails experimenting with air pressure in both chambers. It's lighter than a 38mm stanchion fork, stiffer than a 35/36mm stanchion, has hydraulic bottom out support, and the compression/rebound adjustment has a good range of adjustment. There's an MTBR forum with a ton of peoples' shared setup specs and discussion about different oil weights for different applications - read that and check out their google sheet file. Hayes has really good instructional videos and printed guides for full teardowns and damper bleed procedures.
The fender is pretty crappy. I have a hitch rack on the back of my car and managed to rip 2 of them driving at no more than 70mph/112kmh on the highway. I don't miss it.

Review: Schwalbe's Magic Mary Radial Tires Deliver Top Notch Traction
@aminkis922: my riding is 90%+ on hand cut/natural terrain and I've found the Albert to be a really good front tire, no issues with support when running +4 psi over what I ran on the Specialized tires (settling in on about 26-27psi front, 29 rear) on Bontrager carbon wheels, no insert front or rear. I don't ride in deep mud but on wet roots and wet rocks it's exceeding my expectations. I'm not the fastest rider but I do love blasting through rock gardens and 15+ mile rides. I have the 2.5 inch Alberts and to the ol eyecrometer they do seem to be narrower than the 2.4 Specializeds I had before.

Review: Schwalbe's Magic Mary Radial Tires Deliver Top Notch Traction
I have the Alberts in trail casing, ultra soft front, regular soft rear, dual 29" Stumpjumper Evo. Rolling speed is up from my Butcher trail / Eliminator rear prior combo because the Alberts make my bike feel like it's paving over roots and small rocks common on the trails I ride. Climbing performance on smooth trails doesn't feel very different but I also shed about 100g from the rear with the trail casing. Climbing performance on technical trails is hilariously good, I can just winch up and over anything and it sticks like glue.
I can't even imagine how much grip the Marys must have - nevermind the Shreddas.
