First Look: Sprindex's Adjustable-Rate Coil Spring
@noapathy: Reasonable question. You need a spring that is wound to achieve the stated rate, but will not coil bind at full shock compression with the Sprindex device maxed out. Pairing their device with the correct spring is the only way the mfgr can be sure of that.

First Look: Sprindex's Adjustable-Rate Coil Spring
@dreamlink87: You are correct. Spacers are used to prevent the weaker spring from coil binding and also to time the position in the suspension travel where the tuner wants to transfer the rate to the stiffer spring.

Review: Shimano's XT 12-Speed Drivetrain is Smart Money
I asked Shimano about the plastic and did not receive a clear answer. There is a lot going on behind the sprocket with two screws at each spider junction. My guess is that the fiber reinforced plastic is cosmetic to mask the mounting hardware.

@cru-jones: Good call. I'd love to do a back to back with SLX and GX. Seems Shimano has worked hard to get back into the game.

Review: Shimano's XT 12-Speed Drivetrain is Smart Money
@EnduroManiac: Light flare, not crank wear. That was the best image I had. I am notorious for scuffing cranks (heels in) and these still look new beyond the bashing at the ends of the crankarms.

@ReformedRoadie: Not worried about dirt and scratches. Matte black finishes, however cool they look when the product is new, never clean up after the first dirt ride.

Review: Shimano's XT 12-Speed Drivetrain is Smart Money
@harrybrottman: Shimano XTR cranksets are two forged aluminum pieces bonded together. The manufacturing process took longer to perfect than anticipated, so Shimano shipped XT crankarms with XTR chainrings while they sorted it out.

Not So Fast: How Dropper Posts Created Steep Seat Tube Angles
@tgent: Yeah, it does. The distance from the BB center to the center of the saddle is determined by your leg length, yes. But, maintaining that relationship creates an arc, with the highest point (measured vertically), at 90 degrees - and as the STA becomes slacker, the saddle' height above the bike becomes lower, It's not linear either, One degree slacker from 73 degrees drops the saddle much more than the delta between 90 and 89. Draw the arc on a bike side shot and the relationship will be readily apparent.
