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.

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.

@zenbike - definition 2.

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.

"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.

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.

comment Diagnose grinding sound from single rear cog
It's hard to say. The old 10-speeds tend to be a bit more tolerant of the cog wear problem than newer ones. And if it can't handle the new chain you can try removing one link pair from the old one to shorten it (if it appears that chain length is the issue).

comment Where does the energy loss in cycling go proportionally?
It should be noted that rolling losses can increase significantly on rougher roads. Most of this energy, believe it or not, goes into jiggling the body up and down.

comment Where does the energy loss in cycling go proportionally?
@SGR - Actually, the amount of energy going into cussing out the hill you see coming can get to be quite large.

comment I have a hybrid bike which the frame is too big, is there any modifications I can make to make it more comfortable?
You might consider installing smaller tires. The inner diameter of the tires must remain unchanged, but, for instance, going from a 2.5" wide tire to a 1.5" wide one will reduce the effective bike height a half inch.

(Also check the "related" column to your right for first aid kit suggestions. You don't need a lot, but a few bits can make a minor spill much less unpleasant.)
