Familiarity: I've used it several times

The Lezyne Alloy Drive M replaces my old zefal mtb pump. Its design is much better, and I think that's true for its all alu construction too. It weighs one gram less at 135g and is a little shorter; so, basically the same dimensions. But it pumps more air with a shorter stroke and is far easier to use due to the short rubber hose with both presta and schrader fittings built in and ready to go. On my tubeless 27.5" x 2.8" tires ten strokes yields about one psi. Probably a bit more with a tube taking up space. I run my tires at 15-17psi for better traction and ride, and that suggests I could get a tire pumped up from zero to ride-worthy well before dark. Who rides rough trails in the dark? Not me.

UPDATE: This pump is so pleasant to use, I top up my tires at the trailhead with it. The stated length of the pump is correct for the metal body. If you are millimeter-minded, add another 9mm for the protruding rubber seals and a bit of the stashed hose. Storing the hose inside the piston rod is very clever. Another clever design feature is the loose O-ring above the piston, which keeps the pump from clattering on the up-stroke.

At first I was disappointed in the Highline dropper post because it was not holding position when adjusted. It could creep up or down. I spoke to a Crank Bros. tech, and he sent me everything (by overnight delivery) that could possibly be the source of the problem, including the hydraulic cartridge. The post is now working flawlessly.

This is my first experience with a dropper post and I was surprised that 125mm of travel is really a lot given my size (5'8") and style of riding. I should note that even with the new components it took a tiny bit of use for things to wear in and work perfectly.

Some pro reviews complained that the post rises slowly. Not mine. It's brisk, but not brutal.

This dropper post requires internal cabling, at least in the seat tube. My frame, a Diamondback, provides for that but makes the cable exit the seat tube through a rubber grommet near the bottom bracket. From there the cabling is external. When ordering check the dimension specs against your frame to be sure what you order will fit.

Familiarity: I've put it through the wringer

The tread rubber is high friction and has grippy cleats when walking on rough terrain is necessary. It's super easy to get in and out of these shoes and to adjust them to your feet. They ventilate well and do a good job of keeping mud, gravel, dust, &c out of the shoes. They are fairly stiff, but have some forefoot rocker to make walking tolerable.

They are not especially light, but they're not crazy heavy either. You can't have everything . . . as usual.

I've been using these shoes for a month or so.

UPDATE: July 2018, a year later

I still hold with everything I said above, except maybe calling them fairly stiff. They are stiff. Not great for extensive walking but good for pedaling. The Michelin rubber soles, though, are good when walking on rocks and dirt.
