comment After fall bicycle feels really slippery
Check that the handlebar isn't twisted slightly, and that your seat is properly aligned. If these get out of alignment the bike feels "weird".

comment Steel rims responsible for slicing tubes?
There are at least two different "bead seat diameter" values for 28" tires -- 622mm and 635mm. A 635mm tire on a 622 rim would appear to fit but would be prone to the failure you see. Look on the side of the tire for a 622-nn size or a 635-nn (where nn is the tire width). The old and new tires should match in that first number (the second is not so critical).

comment Inner tube popped on back side of the valve - why?
Question: How did you install the tube? Did you insert it into the tire flat, or did you inflate it a bit first?

comment Inner tube popped on back side of the valve - why?
Strange. There was some piece of something that ran diagonally across the tire, starting at that left-hand bulge and following the abrasion pattern down and to the right. But it kinda smells of an installation error -- got the tube twisted there, maybe.

comment Carbon Wheel Heat Bending
So apparently carbon rims should only be used with disk brakes.

comment Steel rims responsible for slicing tubes?
Also, I have seen something similar on bikes left out in the hot sun for 30-60 minutes. The heat causes the tire to expand unevenly and can lead to it popping off the rim. (Very rare, but it happens.)

I suspect that you have the wrong size tires. If those are 26" tires, in particular, then you cannot just put any 26" tire on the rim, but must determine which 26" "standard" was used to make the rims.

comment Why won't tires go on my Velocity A23 rims?
Shouldn't use tire levers. Should use a Quik Stik.

comment What is the handlebar size for an old road bike?
(Actually, I checked and HF has a plastic vernier caliper for $3.99.)

Purchase an inexpensive vernier caliper. I'm guessing you can get one at Harbor Freight for $4 or so.

comment Using PTFE spray on rear derailleur springs
Not as desirable as a good chain lube. If the lube is gunking up too fast you might switch to a "dry" lube that is heavy on the wax. But neither is good if you frequently ride in the wet.

comment sealed hubs vs normal hubs
I have an old puller/press set that I probably paid less than $50 for. The "puller" is simply a jig that fits in the axle hole and then you use a drift punch through the opposite side to drive the bearing out. The "press" is basically just a regular axle where the cones have been shaped to fit the axle holes.

comment Fixie chain stuck between cog and hub
Use a hammer and drift punch against the cog teeth.

The cable still looks a hair long, but not unreasonable.

comment Why bother changing a chain?
I figure a chain will last 2000 miles with my bike and style of riding. But if I were to go 3000 miles I'd start having shifting problems, and at 4000 the chain would be skipping. At that point the cassette would have developed bad "hooking" and there would be a risk of the chain tying itself in a knot (possibly destroying the rear derailer in the process).

comment Why are chains sold in fixed lengths rather than by the meter?
Most shops would hate the idea. Parts customers would be driven to mail-order because the loose chain is so inconveniently packaged, plus the measuring takes time and the guy to do it might not be handy as the moment. The time spend measuring the chain and packaging it up would easily double the cost of a parts sale. In the shop the mechanic would cut a longer chain anyway, then take it to the bike and fit it.

comment How to prevent the derailleur cable fibres getting all over the places?
You basically cannot solder stainless cable.

comment Rear derailleur cable housing length
There's no great harm from having it too long -- better that than too short. The biggest hazard it that it will get hung up in racks, etc. That said, I'd advise shortening it by 3-4 inches.

comment Why are chains sold in fixed lengths rather than by the meter?
I am quite confident that bike manufacturers can obtain their chains either in bulk or pre-cut to the exact length needed. No one else (other than bent owners) would benefit from bulk chain. (The links themselves cost virtually nothing -- cutting to order in a one-off situation would be more expensive.)

comment Will electric heaters degrade bicycle tires?
Feel the tire after about a hour. If it's more than "lukewarm" you should probably move the bike farther away. Not only would the heat degrade the rubber, but it's also not good for the lubes in the bike.
