Video: Passchier Launches The Gump Bamboo Bars with Arm Pump Reduction Claims
@jaame: layers of bamboo laid and bonded then machined into a bar shape. It's solid. Think of it as vibrocore to the extreme

The flex is the whole point. it's for bikepackers who want super comfy bars and to look hipster doing it

Opinion: Are New Bike Component Standards Really That Bad?
being sram there's probably a big enough manufacturing variance that the 0.01 is superfluous ;)

Throwback Thursday: Fox's Upside Down Prototype Downhill Fork
@faul: what's this supposed to mean? The seal holds in all the pressure at bottom out, so it holds in the minimal pressure from the mass of the oil no problem. It doesn't slowly leak through, just like it doesn't slowly find its way past foot nuts on conventional forks.

Throwback Thursday: Fox's Upside Down Prototype Downhill Fork
@faul: Gravity is not really an issue because seals have to hold in the pressures in the lower leg at bottom out, it's not like the mass of 30ml or so of oil is enough to cause really high pressures at the seal compared to the pressure in the lowers from the displacement of the stanchions. However more important is that the bushings and seals are constantly running in oil, rather than relying on oil being splashed up somehow from the lower lets where it pools. USD Does actually lubricate better, regardless of what seals are needed or not needed. They are still running in oil. BTW here is a graph of the spring only and then the complete fork. Notice how much extra spring force is added by the pressure in the lower legs... https://www.mtbr.com/threads/the-spring-effect-of-trapped-air-in-fork-lowers.1190110/ compare this to the pressure caused by the mass of 30ml of oil

Throwback Thursday: Fox's Upside Down Prototype Downhill Fork
@faul: How is it not an advantage only because the stanchion needs to be sealed? Following that logic no fork orientation has any inherent advantages. In a right side up, the increased torsional stiffness is not an inherent advantage, only designed into the fork because the fork requires a brace to be added.... The USD fork does not necessarily have increased bushing overlap. because it requires a second pair of bushings to be added.... The lefty does not have reduced friction, because it must be designed in such a way that has low friction... I'd like to see a right side up fork that has the bushings and seals actually running in bath oil and not relying on splash/foam rings.
