Stupid question: How do you know your gauge is parallel to the axle?

comment Flat tires every morning
I should mention that there are a few exotic brands of "racing" tubes which are ultra-thin and leak down in about 24 hours. You normally wouldn't have these unless you'd intentionally installed them (though perhaps without knowing the problems they'd cause), but it's vaguely possible that the bike shop sold you a "racer's upgrade" or some such that includes them. (But the simple "slow leak" problem described by others is far more likely.)

comment Why/how did flat bars take over?
Yeah, I noticed the bars getting lower and lower starting maybe 20 years ago. I strongly suspect it's because a bike with a lower (drop) bar looks "meaner" on the salesfloor, and hence is easier to sell to someone who has more testosterone than common sense. This was not a super big problem back in the days of quill stems, but with threadless headsets it's a lot harder to raise the bar to any substantial degree. The result is that the bike gets ridden twice and set aside, which is a shame (and a crime on the part of the bike vendors).

comment Need new 27x1 1/4 (32x630) tires, would the ones stated ONLY as 27x1 1/4 (without the 32x630 specification) fit?
All 27 inch tires are the same diameter, except for "27 five" ones. However, note that any tire made in the past 10-15 years will carry the ISO sizing on the sidewall, in addition to the "traditional" size.

comment How many spokes can break before I need a new wheel?
Once one spoke has broken that puts others under more stress. But certain types of spokes on certain wheels are prone to breakage, especially with age. If the spokes are cheap cad plated ones, vs stainless, then corrosion will get to them in a few years, even if there are not that many miles on the bike. Others, due to the design of the hub and spokes, will begin to fail after a certain number of miles. But a few spokes just fail randomly, and the wheel will be fine after they're replaced. A skilled eye can tell which, but there's no way to describe it.

comment My rear wheel isn't properly spinning. How can I tell whats wrong?
If there are broken spokes on the wheel then that is the first issue to deal with. The wheel will wobble badly until the spokes are replaced and the wheel is "trued". Of course, there may be other problems with the wheel as well, but we can't see enough from here to tell. But no way the wheel will work (for very long) with three broken spokes.

comment Trouble with spiral folding bike lock - jammed
The thing is that you need a lube that will soak into the lock, and not leave a residue. Not simply to preserve the lock for the future, but to get the stuck parts sliding.

comment Trouble with spiral folding bike lock - jammed
I would avoid the WD-40 and find a lock-specific lubricant, from a locksmith or hardware store.

Well, you could always replace the piston with a piece of solid pipe.

comment Is there a “conventional” configuration for mounted accessories?
You can use a Velcro strap to secure the pump under the top tube. There is a strap specially made for this duty (though such specialization is not really necessary).

comment What is the minimum repair kit/parts I should bring on a 150 mile bikepacking trip?
On the GAP I wouldn't recommend burying anything -- use the trash cans. Soiled wipes should be kept out of flush toilets but can be placed in most porta-potties and the like with a clear conscience.

comment Smooth tires on wet road?
@WillVousden - You forget that pressure also figures in, and having more PSI pressure also contributes to traction. The less contact area the higher the PSI.

comment Smooth tires on wet road?
(Net-net is that both sides of the argument are talking out of their posteriors, and I've never seen any halfway-decent research on how tread should be matched to road conditions. But the vast majority of road bikers' experience suggests that having heavy treads does not contribute to safety. The issue is more with the fine treads you see on many road bikes -- what is ideal when?)

comment Smooth tires on wet road?
The real issue is the presence of a thin layer of scum or mud on the road. Having some sort of tread helps with this, but the specific "ideal" tread depends greatly on the nature of the scum.

Baby wipes. Work as TP and also for cleaning stuff.

comment Smooth tires on wet road?
"Aquaplaning" is something that occurs on wide, low pressure auto tires at 50 mph. A typical narrow, high pressure bike road tire will not aquaplane until perhaps 100 mph.

comment How to tell the size of a bike chain?
Yes, when matching old chain length to new it's important to count links, not simply measure overall length. The old chain will have "stretched" at least one full link in length, probably.

comment How to tell the size of a bike chain?
@Criggie - Length isn't very critical, since virtually all chains come with extra links. It's basically the width of the chain that is the issue.

comment What is the minimum repair kit/parts I should bring on a 150 mile bikepacking trip?
Yeah, it's critical to have adequate sun lotion (and use it before you notice you need it), and having some bug repellent is helpful too. Last year I had along a bunch of "Off" brand "Deep Woods Towelettes", which are individual wipes, saturated with bug repellent and sealed in individual packets. One of these could be stretched to "treat" 3-4 people at a stop, and my companions were delighted to get the left-overs after I'd used one on myself.
