comment Geometry between 50mm stem and a 65mm stem and riding experience
Yeah, 90 meters might be a bit too much. ;)

That's a little over half an inch. Not enough to make a major difference unless your bike is badly miss-sized to begin with, though it probably is just enough to feel.

comment What are the disadvantages of “puncture proof” (or puncture resistant) tires?
@JamesBradbury - The "Quick Stick" is a nylon rod maybe 7" long and 1/2" diameter, with a sort of crochet hook cut into one end. It takes a little practice, but except on exceptionally narrow/tight tires you can hook the stick under the tire and have it dismounted in about 30 seconds. Since the rod is fairly large diameter with a rounded end the danger of puncturing the tube is virtually nil.

comment Why does my bike make a noise when I pedal hard?
Oiling the BB is not going to fix anything, and generally you do not want to put oil into a BB. (Use a good quality bearing grease.) You need to get the right wrenches to tighten the pedal, the crank arm, and the BB cups.

comment Is a 100mm travel hardtail ok for light downhill and a few jumps?
Back about a hundred years ago, a group of negro soldiers in the US traveled, I think, about 1000 miles across the American West (often no roads to speak of) on wood-framed bikes. This was to demonstrate the ability of bikes to replace horses in military operations. The major innovation on their bikes was steel rims in place of the older style wood ones. Any bike you have will be 10 times better than what they rode over some fairly rugged terrain.

Well, then, it sounds like something was defective from the factory. Probably if one could look at it first-hand it would be fairly obvious, but I can't see it from here (especially since you replaced the parts). (I hope the crank arm was replaced with the BB cartridge -- the hole in it no doubt got worn.)

It sounds like the crank arm was probably shot, with the hole in it not tightly fitting the BB shaft. (Or else it was the wrong type of arm for the shaft.) This would cause the bolt to keep loosening and there would be wear where the arm rubbed against the bolt. Or else somewhere along the way a bolt was cross-threaded and damaged the threads in the BB.

Some cyclists have been known to work little pieces of leather into the "crosses" between spokes, to prevent them from making noise.

Of course, that was not a failure of the BB proper, but rather a failure of the crank-BB connection that resulted in damage to both. This is caused by allowing the crank fixing bolt to work loose, or perhaps never having it tight enough in the first place. There are generally noticeable warning signs (including noise) that the bolt is loose before damage occurs, if you know to look for them.

comment Advice for increasing endurance
Do whatever it is that seems to demonstrate your lack of endurance, only do it a little longer and more aggressively each time (with appropriate rest intervals between).

I seriously doubt that the BB is in need of service. More of a grinding sound would be present in that case. But crank arms, pedals, and cartridge BB cups are all suspect.

Maybe it's not your bike -- it's your body. ;)

comment How do I properly adjust a front derailleur?
@CareyGregory -- If a derailer "springs out" the cable will be pulling it in, and you'll notice as you adjust towards the larger ring that the cable feeds towards the derailer and becomes more slack. And, with the cable removed or totally slack the "springs out" derailer will be positioned more or less over the large ring.

comment Why choose a traditional frame over an aerodynamically streamlined frame?
Like I said, the wheel-hugging seat tube WOULD have an effect. "Aero" shaped tubes, no. And in this test there's a strong chance of a placebo effect -- in fact, in the first trial the rider averaged (roughly calculating) 96 watts, while in the second case he averaged 127. You tend to go faster when you expend more energy.

comment Why choose a traditional frame over an aerodynamically streamlined frame?
@R.Chung -- OK, I should have said "significant" rather than "measurable". I can't see how streamlined tubes would reduce the drag of bike and rider by even 1%, and that advantage would disappear under real-world conditions.
