Talking Telemetry and Downhill Bike Setup with Giant's Dave Garland
@UtahBrent: There's no reason to assume spoke tension always remains above zero in a DH context. This is where Sheldon Brown's argument falls over. I'm suggesting that the forces involved in DH riding can be enough to slacken the spokes at the bottom of the wheel (for a vertical impact) or on one side of the wheel (for lateral loads). Spoke tension affects how much the rider can load up the wheel before the spokes opposite the load go slack. If each spoke has 800N of force on it, that's 800N the rider can apply in the opposite direction ("squashing" that spoke) before that spoke goes slack. Most spokes won't directly opposite the force applied, so 3200N or a bit more would be enough to slacken the spokes. Spoke tension will directly affect how much force the wheel can take before the spokes opposite the wheel goes slack, and the wheel starts to flex.

Talking Telemetry and Downhill Bike Setup with Giant's Dave Garland
Spoke tension doesn't affect lateral tension, it affects total wheel compliance, holding the axle fixed and deflecting the rim. I assume you've seen the ubiquitous slow-mo footage of riders cornering with the rear wheel locked (i.e., skidding through a corner) and the rear wheel deflecting and springing back each time it contacts and leaves the ground? That's the movement spoke tension importantly affects: for a given type of spokes, tighter spokes means less deflection or more stiffness. This is because the spokes act as a spring, pulling the rim back onto the axle's plane, and more tension effectively preloads the spokes, giving a higher initial spring rate. Besides, Garland isn't the only guy doing this - Manon Carpenter's mechanic laces her wheels at lower-than-normal tension to make her wheels more compliant. It's a thing.

The Campaign for Worse Bicycles – Opinion
I've only ever owned two proper mountain bikes, and I also find it hard to relate to the opinions of an author who appears to have owned dozens of bikes, and probably reviewed hundreds. Nonetheless, as a heavy, probably aggressive rider, I break and replace parts pretty regularly, and I feel like my attitude towards part selection is the same as Wragg's attitude towards bikes. I run tires and wheels that are way too overkill for my 150/160mm Commencal Meta, which makes the thing a pig to get up a hill, but I keep them on because they absolutely sing on the way down. I have an 810mm bar that's always clipping trees, but I'd never cut it down. I could put more sensible parts on, and get a more VW-like experience out of my bike, but whenever I have, I've gone back to overkill pretty quickly afterwards. Bikes are tools with a purpose, and that means a certain level of VW-ness is good, but they're also playmates, and that calls for a bit of personality as well.

Trek Session 29 vs 27.5 – First Ride
It'll be a cold day in Hell when the bike industry gives us quantitative/numerical data on any new product's performance. The line between journalism and advertising is pretty blurry on the ol' Pinkbike.

Spartan vs Spartan: Devinci Enduro Team Bike Checks
If you're saying you're tall, don't worry, Pole's got you covered, and in a season or two everyone else will as well. If you're saying you're heavy (like me, 250lb), yeah you're fucked.

The Commencal Furious is Here
@whitebullit: Dude the Furious isn't replacing the Supreme. It's designed to be fun, whereas the Supreme's designed to be fast. Thirion rides the Supreme because it's faster. Note the entire video was comprised of freeride and bike park footage, and didn't feature Thirion or Brannigan.

Spot's New 29er Has a Carbon Fiber Leaf Spring – Sea Otter 2017
@WAKIdesigns: Waki, your flaccid member and breakaway friction have nothing to do with small bump compliance. The leaf spring increases the spring rate in the mid stroke, boosting mid stroke support. Coupled with a progressive overall rate to prevent harsh bottoming, this permits a lower shock pressure, increasing small bump compliance.

Devinci's 30th Anniversary YYZ Bike
Pros: they solve clearance issues around the bottom bracket by making it easier to fit the driveside stay past the chainrings. This is particularly handy when the stays are really short or the tires are really wide, which is why they were resurrected for the Yeti 650b-plus bike. They also helped a lot when triple-ring setups were the norm, since it was harder to fit the stays past all three rings. Cons: they constrain the range of options for designing linkages on duallies, particularly by making it hard to keep the lower pivot close to the BB. This is less of an issue on single-pivot bikes, which is why Orange uses them. They also tend to create a lot of chain slap, as the chain acts like a trampoline and shoots up towards the nearby underside of the stay, although this is also less of an issue now that clutch-equipped derailleurs are a thing. Overall, they're suboptimal for multi-pivot duallies, but fine for a hardtail.
