comment Hub rebuild - cone dust cap conflict, hub integrated vs pressed on cone?
This sounds somewhat similar to the problem I had last year, where the front hub started making swish-swish sounds. Replaced bearings, cone, and axle, and it began doing it again within an hour's ride. The original axle showed signs of stress (distorted threads), apparently due to the cone and lock nut being tightened against each other by the motion of the wheel and a dragging bearing. Finally had to get a new wheel. (IOW, keep an eye on the hub after you put it back together.)

Note that you should be able to reuse the old cones, unless they were damaged when the axle broke. (And also note that there is some danger that the hub was bent or the races were scored when the axle broke.)

If the cone is the correct diameter to mate with the hub's dust cover then you can probably get away with removing the cone's cover. There is a danger, however, that the cone is simply the wrong one to use with that hub, due to a different bearing circle diameter.

comment Loose pedal bent under pressure
Stupid question: Is is possible that the crank arm is bent, due, perhaps, to dropping the bike on the pedal? Or perhaps due to climbing a steep hill with a fixie when the pedals or cranks were not up to that much force?

I definitely WOULD NOT reinstall that pedal. Not unless the threads were proven to be perfect on very close inspection.

comment Can I use a 6mm threaded bolt instead of a bleed valve for hydraulic brakes?
If I found a bolt that seemed to fit pretty well I'd consider getting an O ring that fit snugly in the hole, insert that, then the bolt. Depending on the geometry of the hole that might or might not work.

@moshbear - Except that the threads of a standard bolt are not tapered, like the threads of a pipe are. And you risk getting fragments of the tape in the fluid, where they could easily cause a braking failure.

It seems a bit odd that you can't get the pedal OFF. Are you sure you're turning it in the right direction? The left pedal threads backwards, remember.

You can edit your question to insert the "answer".

I would guess that you need either a bolt with a tapered end or a gasket of some sort, in order to achieve the proper seal.

If using heat after penetrating oil, beware of starting a fire. Wouldn't be a big fire, but could take you by surprise and set something else on fire.

(It would be of interest to know the type of metal used for the seatpost and the frame.) (And I'd probably strap the frame to something solid and use the pipe wrench, after letting some penetrating oil soak in for a few hours.)

Dynamite is probably the best option. (And you're right that seatposts come in a stupid array of sizes, and it probably is possible to hammer in one size too large in some cases.)

comment Brand New bike, chain slips into spokes on first gear
One does need to point out that many discount stores employ an itinerant bicycle assembler person of at least moderate mechanical skill. This person appears several times a year to assemble bikes, and may be scheduled back at your store or another one nearby in the near future. If that cannot be arranged, then Walmart should either foot the bill for a bike shop adjustment or refund your money in full.

Take it back to Walmart and demand that they assemble and adjust it correctly.

comment diference between 170mm 172mm 175mm crank arm length on road bike
"Optimal" crank arm length is determined by the individual's physiology, the height of the BB above the ground, and desired ground/turning clearance. Obviously, a longer arm gives more leverage, and a shorter arm is better for people with short legs, but there's no "formula".
