It’s Time to Recalibrate Our Ideas About Chainstay Length
Was going to post along these lines, not saying that he's wrong on how the bike feels but the physics seems to be off

There's no 'Mout' in from of Snowdon, it's just Snowdon, or possibly Yr Wyddfa if you want to give it its Welsh name

Jamie Edmondson Parts Ways With the RockShox Trek Race Team
Leaves makes it sounds like it was Edmondson's choice whereas this sounds as if Trek's choice. 'Parts ways' is nice and ambiguous

Interview: World Cup Downhill Riders' Union Rep Emilie Siegenthaler
@Puddings: For most brands in DH, the aim isn't to sell DH bikes specifically, it's to raise the profile and prestige of their brand so that people choose their brand regardless of what travel bike they're after. Think Danny Hart on Cube, Cube aren't hoping to sell many DH bikes buy they are hoping to sell a lot of e bikes. I also can't imagine the demo sales justify the existence of the Specialized DH team but knock stumpjumper, status, and endure sales might. I will never buy a DH bike but DH is the only mtb discipline that I am ever likely to follow closely and nake the effort to watch live and I imagine that I am pretty typical of mtbers

Finals Photo Epic: Val di Sole DH World Cup 2022
While at the time, Godstone was way ahead in the splits, it feels a little disingenuous to report it like that and not mention that Williams subsequently pretty much matched his times, 0.03 behind at split 3 amd then up at split 4, so the comparison with Hill doesn't quite hold, Hill would have won by a massive margin had he not binned it on that corner but Goldstone had less than a 50% chance of winning, was behind at the final split, even if he hadn't binned it. Like with world chanps though, thrre seems to an unwarranted assumption that Goldstone would have won if he hadn't crashed which is disrespectful to Williams. As a side question, had anyone made cutting that corner work for them?

[Updated for Finals] Start List for the Val di Sole DH World Cup 2022
I assumed that they still had qualifying, there just weren't any points for it. Certainly in previous years the top riders didn't go mid way through the pack. This is probably the qualifying order

Final Results from the Les Gets DH World Champs 2022
@evantfulrides: Williams was up at splits 1 and 2 regardless of Goldstone's crash between splits 2 and 3 so even if Goldstone had stayed on his bike there is no real reason to believe that he would have won

Nerding Out: Do Kinematic Graphs Really Describe Suspension Performance?
Why is a 4 bar more plush off the top than a LDSP? This is actually one of the easier questions, the key difference is that 4 bar allows you to eliminate brake jack. When braking the brake makes the structural member that the brake is attached to want to rotate in the same direction that the wheel is going. On a LDSP this causes the chainstay to try and rotate which compresses the shock and stops it working as naturally. On a 4 bar the bearing between the chainstay and the seatstay prevents this moment from trying to rotate the seatstay and thus the shock is much less affected by braking

Pinkbike Poll: Do You Care About the Carbon Footprint of Your Bike?
This, from a UK perspective, most of the UK main population centres are quite far from the best riding. While UK cars may on average be slightly smaller/more efficient than in the UK, most people are doing more than a 15 mile round trip to ride. While you're doing that, the carbon footprint of the bike itself is essentially loose change. However, of you don't drive to the trails and do use the bike to replace car journeys then even if you have the newest carbon fibre e-bike it will quickly pay for itself in emissions saved

Tested: How Much Slower Are Idler Bikes For Climbing?
It makes sense that the indoor losses were higher than the outdoors losses. Outdoors, with the shock locked out, your losses are mainly comprised of drag, rolling resistance from the tyres and drivetrain losses, whereas indoors the drag and rolling resistance from the tyres disappear. It is reasonable to assume, that with the shock locked out, and the same tyres and tyre pressures, outdoors there is not much difference between the two bikes for their drag and rolling resistance figures. The idler appears to add 2.3% to the drivetrain resistance but drivetrain resistance is only one factor in the total losses that you experience while pedalling and therefore the affect on the total losses will be less than 2.3%. In this case, it will vary depending on speed and other factors, it would appear that drivetrain losses accounted for about 65% of the total losses: 2.3 x 0.65 = 1.5. The other 35% of the losses didn't change significantly between the bikes for the outside tests and this is why the drop in performance is more pronounced in the indoor, as the 35% of unchanging losses have been removed from the test.
