comment Can I increase my highest gear ratio?
Too slow for what? Do you feel the need to expend energy to go 1mph faster? Most of the energy you add at high speeds is just burnt off as wind resistance, with very little speed increase.

comment How do you install a hub dynamo?
Wheel building is something that a reasonably competent, mechanically inclined, and, most importantly, patient person can learn to do, but a dyno hub is probably not the right place to start, since the shorter spoke length makes the job more difficult.

comment How do you install a hub dynamo?
You can "rebuild" using an existing rim, but rims are relatively cheap (and it would be foolish to try to reuse the spokes). Better (and perhaps cheaper) would be to buy a suitable wheel already built with the dyno in it.

comment Can I increase my highest gear ratio?
Of course, one way to increase effective gear ratio is to install a larger diameter rear tire.

comment Can I increase my highest gear ratio?
Serious question: Why do you need to go faster downhill?

comment Clipless shoes & pedals and long distance
I've ridden dozens of 70-mile days with SPDs. And before that I used toe clips. With the toe clips, after 5 hours or so in the saddle, the toe strap would begin to bite into my foot pretty badly. I do not have this problem with SPDs.

comment How to nail clipping into race pedals without looking?
What I do with my SPDs is to pedal with my instep until I get moving, then clip in "at my leisure". And I find the style of pedal makes a lot of difference. My (Shimano) bike pedals are fairly easy to clip into, but some (no-name) pedals on exercise bikes at my gym are a lot harder.

comment Is deep v wheels safer then the standard fixie rims
+1 - I especially liked your last paragraph.

comment Suggestions for winter cycling glasses?
I've thought about this, and if I were to get back into winter cycling I'd try some inexpensive lab goggles and cut out the screens in the vent areas, to allow more air movement.

comment What is the frame called that fits 700c wheels?
Yes, measuring the frame from dropout to brake pad would be the way to tell for sure. Or simply measure the radius of the wheels that are on the bike. Do note that there are likely some old (prior to about 1985) 27" bikes out there that are very close, only the brakes won't line up very well. (Kinda seems like this is the tail wagging the dog, though.)

comment What is the frame called that fits 700c wheels?
And, as was noted in a comment, a "29er" uses 700c rims.

comment Chain repeatedly tries to click into place without gear change
The first thing to do is to make sure that the derailers are properly adjusted. Beyond that a worn chain or cog. If you don't know much about bikes, go to a local bike shop and ask if you can watch while they check out the bike.

comment Can I use friction shifters with a clutch style rear derailleur?
As I read the "clutch" description, it's merely a friction damper to reduce chain slap (which has got to get bad on those 17-cog rear clusters). No doubt it's rigged so that when cable pull increases a bit the friction is reduced, to make it easier for the chain to "climb", but that effect would be essentially the same with indexed shifters and friction shifters.

comment Any issues with wearing leg warmers over tights?
Now that I no longer do winter biking, I wear my old Col d'Lizard Polartec "Powerstretch" tights when I run the snowblower in zero degree weather. On a really cold day I'll wear jeans over. The branding has changed but I think these are essentially what I have.

comment Would learning to ride a unicycle boost biking skills?
My opinion (being neither a uni nor MB rider) is that it can't hurt. It's too easy to become "overtrained" in a particular specialty, and the result is that the body loses strengths and skills it would otherwise have. "Stretching" yourself is goodness, within reason. (And who knows, it may be a good way to meet girls.)

comment Do I really need to use primer first?
If you're painting bare metal you need a primer -- one speced for metal -- even if the paint claims you don't. (You can get away with spot-priming if only a few areas are down to bare metal.) If you're going over old paint you just need to clean it and sand lightly before painting, though without a primer you may experience paint incompatibility in a few cases. There are, alas, many ways the job can go bad.

comment (Automatic Bike Project) amount of torque required to change gears?
Here it is for you, an article in IEEE Spectrum from last May. Lays it out in pretty good detail. There's a link to another web site (diyshift.com) for a different design, but unfortunately that link is dead.

comment Using a much heavier rear tyre than in the front
It's not uncommon to have a larger tire on the rear, since it carries more weight, generally. I've no idea what the added weight may do to jumping, since jumping is against my religion.

comment Buying brake levers, how do I find the correct ones for my bike?
Your need is to find a lever with the proper shape and fit to replace the old one, and also with the proper "cable pull" distance. "Cable pull" differs about 2 to 1 between older caliper/cantilever levers and newer V-brake levers. Most likely your discs are designed for V-brake levers, but it's hard to say that with certainty.
