A $999 Wireless Dropper Post, New Tires, Tools & More - Taipei Cycle Pre-Show
My guess is it takes more force (and therefore more current draw on the battery) to open the valve if your body weight is already pushing down on the seat post. If you open the valve while unseated and THEN push the seat down it would require less force to open the valve.

Review: Feedback Sports Team Edition Tool Kit
@vinay: "But I don't know what the folks at Park were thinking, there is no way to rotate the cranks without the pedals smashing the tray." I thought the same thing for the longest time, until I realized you can put the tool tray on the back side of the bar.

Injury Update From Greg Minnaar
@BEEner: I had a radial head fracture from a crash about a year and a half ago. I think there are varying degrees of "fracture" because mine hurt like hell. Almost passed out from the pain/shock. In the crash my elbow got forced to bend backwards under the weight of my body and the radial head snapped clean off and was not even aligned with the rest of the radial. Some ligament damage as well. I needed surgery to add a titanium plate and 7 screws to re-attach the head to the radius. Arm was stuck in a splint at 90 degrees from wrist to shoulder for 3 weeks. Couldn't even ride a bike around a parking lot for at least 6 weeks after the surgery. All good now, but my elbow does make a strange grinding feeling when I rotate my hand palm up to palm down.

Development Story: Cannondale's Wild New Single-Sided, Single-Crown XC Fork
@Mojo348: With bushes, the stanchion tube would just spin around inside the fork leg. The roller bearings ARE required for the one sided design, but the primary reason is not because bushes would have too much friction, it is because bushes simply would not work. There needs to be some sort of anti-rotation factor to the design, which the three (or four) sided roller bearing flats achieve nicely.

Cane Creek's Titanium Enduro Crankset - First Look
Know where else titanium and hirth joints are used??? Gas turbines. This thing is basically a freakin' jet engine.

Cane Creek's Titanium Enduro Crankset - First Look
@yeti951SD: That is a picture of the "Sweet Wings crankset from the mid-1990s" The new ones do not have a chain ring spider... because it's not the 1990s anymore.

Garbaruk 10 x 50 Wide-Range 11-Speed Cassette for SRAM XD Drivers - Review
@zdebruine: One piece construction would require a whole lot more machine time since you would have a hell of a time hollowing out the billet from the back side of the cassette. That last (largest) cog has to be the one to have splines that drive the XD driver body. It is the only logical way to design it from a load transfer standpoint. I suppose you could do some sort of torque tube driving off one of the smaller cogs, but that would require a lot more strength at the small end of the cassette since it would then see huge stress when climbing in a large cog. All steel is easy. One piece construction is not.
