Giant Trance - First Ride
@mecabeat: I agree with your point about quick releases not being valid protective devices, and obviously not being on both sides of the bike. I'm not sure I would ever even look at them that way. But I still really like being able to quickly, and tool-lessly, take off one or both wheels to either put my bike in the trunk of a car, or to fix a flat quicker.

I Say "E-bike", You Say... - Sea Otter 2016
Yes. So let the 0.0001% of people with a physical disability have an E-bike, made for those who need it. Not mass produced. My guess is that there have already been more E-bikes produced than there are disabled people in the entire world. No need for the largest bike companies in the world to be producing these, in mass, with no intention of marketing or selling to disabled people. They're being built for the public. Martyn is a good example for sure...of someone who has had a custom made bike made for him to suit his disability.

e.thirteen Introduces TRS Tires and Wheels
@jflb: As a professional bike shop mechanic at more than one bike shop over the past nearly 20 years, I, like @hampsteadbandit, have built hundreds of wheelsets, and have repaired easily over a thousand. My old shop was even the official builder for American Classic wheels, before their operations were moved to Florida. Without a doubt, the most common failure seen with J-bend spokes is at the J-bend, at the hub. Yes, I've seen quite a few spokes break where the threads start as well, and also some that snap in the middle somewhere, but without a doubt, 80% of broken spokes that I've seen are at the J-bend. I'm not going to speculate on why this is (spoke quality, poor initial wheel build, hub/spoke interface tolerances), it's just the data that is there And for the record, I absolutely recommend *against* alloy nipples on practically all wheel builds. No linseed oil or twisted spokes for me either.
