Magura MT Trail Brakes – Review
Can't believe there's so much hate for Magura brakes on here. It's not like the MT2 or 4s aren't a screaming deal. My last pair of MT8s didn't need to be bled through four years between several bikes before they got sold on a complete. Same story with my current pairs. They are difficult to bleed or install when compared to shimano or sram, but the bleed holds much longer. Pads last much longer than other brands. They don't do that thing that every single XT brake does--i.e. leak small quantities of mineral oil past the piston seals and contaminate the pads. Power is higher than the 8000/9000 series. Modulation is on par with guides. Unlike other brakes, I don't have to constantly worry about Maguras. The one time there was a problem with a master cylinder, Magura USA provided top-notch support.

Does Boost Spacing Really Make a Stronger Wheel?
Wait. So instead of adjusting spoke lacings, using an asymmetric rim, or adjusting flange height, American Classic is trying to convince me that narrowing flange spacing will produce a stiffer wheel? Pure hokum. Of course--having similar spoke tensions is great! I aim for it on any wheel builds I do. But this whole hand-wavey "rim doesn't get pulled" argument I don't buy. Show calculations (complicated if you're making a kinematic argument), simulation data, or real world data. Actual testing has shown that bracing angle is a signifiant factor in wheel stiffness.

Bontrager Line Pro 30 - Carbon Wheels You Might Actually Be Able to Afford
The old Bontrager hubs were poorly designed. It appeared the pawls were too close to the center axle. The load had to be super high to deliver the applied torque, and the freehub body would just fail via overload or low cycle fatigue. New design looks much better. It's a spitting image of industry nine's freehub body. Which is a bit of a bummer since I love those folks, but the torch freehub has held up very well for me and requires very minimal service compared to any hub besides DT swiss. I9s have extremely good tolerances, though, and the first gen hubs the pawls would eventually move in the freehub body and cause occasional slipping--so I wouldn't know if these get the same performance as the torches. DT is still by far the most reliable hub on the market. Think about it--those ratchets are spreading the drive load out over almost the entire freehub body and circumference of the hub shell. They have huge springs, and there's nowhere for something to slip or migrate to an incorrect location.

Trek's New Fuel EX 29 and Remedy 27.5 - First Ride
@jflb: Their mountain frames no longer use BB90. Trek's long overdue abandonment of BB90 is the reason I now own several of them. My experience with BB90 has never been to find a customer with a 10k dollar bike being stuck. However, pretty regularly, frames that were otherwise in perfectly good condition needed to be warrantied due to bottom bracket wallowing. If anything, Trek's owners should have stepped in since they appeared to be loosing so much on warranty support for a failed engineering idea the designers stubbornly clung to. Interestingly enough, I haven't seen bottom bracket wallowing issues in the latest and previous generation of emonda/madone. It's possible (though doubtful) that the design has been improved/fixed.
