Prologo Announces New Line of XC Gloves with 'CPC' Vibration Absorption Technology
@trillot: @Riggbeck: Your points seem to touch on a real point of division in glove/grip design, that I've pondered as well. It is perhaps best exemplified by looking at the Specialized Body Geometry glove designs over the past 20-25yrs. Even within just that one ergonomically oriented line of gloves, they at various points used both strategies, and variations thereof. They started off with padding the ulnar nerve on the outer heel of the hand, with the thought that ulnar pressure was the problem for most people suffering hand numbness, so they tried to help by directly giving it extra padding. Then they went to a central mound to spread the load over a larger area, exactly as you suggest, shifting the load off the original problem spot through redistribution. Now they're kind of doing a perimeter padding again, but instead of just the ulnar nerve it goes across the whole heel of the hand and then up around the base of the knuckles. Notably, it has a gap in the hollow middle of the palm, so it seems that they've abandoned shifting the load to that area. They do a lot of pressure mapping, so perhaps they found they could reduce ulnar pressure with more surrounding padding, or perhaps they found negative carpal effects from the central mound padding shifting the load there. Anyway, interesting topic, and I am glad to see other folks out there are pondering it as well.

Porsche Acquires Majority Stake in Greyp eBikes
@Chuckolicious: Some bike companies have already offered bikes with natural fibers (usually Flax) in place of some of the carbon. Usually they have claimed superior vibration damping as the main benefit. The two that spring to mind are Look and Museeuw on their road bikes.

Gee Atherton Airlifted to Hospital After a Crash While Filming
@fatduke: Sorry to hear about your injury, I hope that vision continues to improve! Kite boarding has always seemed like a really cool sport to me, but I'd always assumed the main risk was drowning. What broke your eye socket? Was it impact with the water, or some of your gear?

Video: Celebrating Larger Riders in 'All Bodies on Bikes'
@wiscobiker: Yeah, that is an excellent point. They've had the Clyd category since at least the mid to late 90's, so there is a great example of the sport (in its racing guise no less) being inclusive decades before it became trendy or socially required.

Tested: Does a Lockout Actually Make Climbing Faster?
@justinfoil: While noplacelikeloam seems to agree with your counterpoint to his comment, I was under the impression that noone here is arguing that seat height is being compromised by suspension movement. Instead, they are arguing that seat position is being compromised, which is a different thing. Effectively, as the rear shock compresses on a climb, you are slackening the seat angle, and thereby changing where the riders center of gravity is relative to the BB, what angle the saddle is relative to level, etc... Effectively, rear shock compression on a climb will have the opposite effect as the move toward steep seat angles, slammed forward saddles, and nose down saddle angles that have been becoming increasingly popular, due to their claimed benefits for in the saddle climbing. It is also somewhat like going up a very steep hill, where it becomes progressively harder to pedal effectively as you feel like you are shifted into the "back seat" of the bike and you have to hunch further and further forward over the bars in order to maintain somewhat normal front to rear wheel weight balance. If you take it to an absurd level, just as a thought experiment, you could imagine being rotated so far that your saddle height would be the same, but the biomechanics would actually become those of a recumbent bike, which are totally different, and not noted for being advantageous on climbs (although they do have advantages on the flats).

Tested: Does a Lockout Actually Make Climbing Faster?
@MaplePanda: Yeah, I agree on the telescopic fork and common road surfaces not being a good match. If I remember correctly, that BQ used in the test WheelNut is referring to was a Rock Shox Ruby, which was part of their brief foray into road bike forks in the 90s. Besides the bushing slop you mention, it also only had something like 28mm stantions and curved lower legs to mimic a steel road fork, all which would increase the type of flex you're referring to. On a related note, the Lauf fork with its carbon leaf springs seems like the layout that would be best suited to the high frequency of pavement vibrations.

Slack Randoms: Concept Bikes, Bobsleigh Tracks and Centaurs
I just asked a question about that above, and was continuing to read down through the comments to see if anyone else had an idea. At least I know I'm not alone! I don't see any stick or boom for a rider/bike mount, and it seems too close and with too much tree cover for a follow drone.

Slack Randoms: Concept Bikes, Bobsleigh Tracks and Centaurs
Since it seems like you watched the bobsled vids closely, do you know what kind of rig would have been used for the alternate view 2nd vid, with the rap soundtrack, where the cam is behind and to the left of the rider? I don't see any stick or boom for a rider/bike mount, and it seems too close and with too much tree cover for a follow drone.

Bike Check: Pyga's Custom 1993 Iron Horse FS Works Inspired Hyrax
Yeah, it would be pretty funny to calculate the anti-squat on this thing. It would be insane by modern standards in any gear, but in the granny would be off the charts! I guess with only 55mm travel you can get away with a lot more design flaws, as the suspension isn't moving a whole lot anyway, so chain growth, or excess rebound from bad damping, is limited in its impact.

Bike Check: Pyga's Custom 1993 Iron Horse FS Works Inspired Hyrax
As I recall, after retiring from MTB racing due to his heart valve issues, he'd briefly worked for Oakley, but apparently didn't dig boring office life and quit in short order. As of maybe 8-10yrs ago, he was working for a moto accessory company called Two Brothers Racing (twobros.com) in SoCal, but not sure if that's still the case. And you're right on about him being a boss back in the day. I can't even count the times I have seen that pic of him jumping the bridge in Bromont posted on walls in garages, bike shops, etc... and his big air riding style is made all the more impressive when looking at it in retrospect as we now have perspective on how sketchy the bikes were, whereas back then we all just took it for granted.
