comment Why should I choose 36 or 32 spokes (or another number)?
In addition to a slight increase in weight, more spokes causes a slight increase in air resistance. But the difference is not significant unless you're riding in the TdF. But fewer spokes is "sexy" (to some people).

comment My bike Crank is making noise like Tuk, Tuk… once or twice when I pedal hard
The possibility that would be most concerning is that the crank arm is loose on the spindle. This can wreck the arm and spindle if not corrected immediately. Beyond that there are a dozen different possibilities -- bad pedal bearing, bottom bracket cartridge shifting between the cups, loose chainrings, a slightly bent tooth on a chainring, "frozen" chain links, etc.

comment Is it possible to get a slow leak straight after installing new tires?
Pump up the tire and spit on the valve. Do you see bubbles?

comment Is the same effort required to maintain a set speed using different sized chainring / cog combinations with same ratio
@ChrisinAK - Reducing the mass of the chain has virtually no effect.

The net-net is that any differences are due to differences in friction, plus going to a fixie you might change the crank extension slightly which could have a tiny ergonomic effect. Any such effects are pretty negligible and hard to predict.

comment Don't know spindle size?
There are, I believe, only four different spindle types, and they can be differentiated by just looking at them (though you may need to remove a crank). You don't need to know the spindle diameter. The length is another matter -- a little tricky to measure.

comment Tyre bulge when inflated, new
Double-check that the tire is seated at the rim properly. If you look closely there will be 2-3 ridges in the tire sidewall, running in circles around the sides, near the rim, and, when the tire is properly seated, a given ridge will be a constant distance from the rim. If you see the ridge wavering in and out at the rim you need to depressurize and work the edge of the tire in or out to make it even. If that's not the problem then it sounds like you have a defective tire -- rare but not impossible.

Use a toothbrush. (Not yours, your wife's.)

comment Matching color bar tape to replace dirty white tape?
(Note that replacing bar tape is not as easy as it looks. The stuff is really poorly designed -- dunno why no one's ever improved on it -- and it's hard to apply such that it won't shift with use.)

comment Matching color bar tape to replace dirty white tape?
I just go to a sporting goods place and buy hockey tape. Comes in several colors. Gets dirty fairly fast, but it's easy to apply -- just put it over the existing tape -- and when it gets dirty just add another layer.

comment Which direction should QR lever point?
If the lever touches the fork or rear stay it's not tight enough.

comment Which direction should QR lever point?
I have heard one credible story where a person drafting too close got their wheel between the lever and frame of the bike they were following, causing the wheel on that bike to come loose.

comment Which direction should QR lever point?
Honestly, it doesn't really matter that much. If you ride through brush you probably want it pointing backwards so as not to get hung up, but on the road pick whatever orientation seems appropriate to you. You may find, eg, that a certain orientation is apt to get caught on pant cuffs (if you cycle in long pants) and that's reason enough to change. Or you may find that an orientation causes problems when attaching panniers. Whatever.

Note that about a year ago someone was pushing nearly the identical bike but with the pedals on the front wheel.

Just ride. Don't obsess over having a highly detailed "plan".

comment Why would the tension screw on a Brooks saddle have unscrewed to zero? What negative effects?
You're sure the saddle didn't just stretch out?

comment Are fatbikes capable riding in mud?
Assuming the mud is of uniform consistency for several inches of depth, there is a maximum practical pounds per square inch (PSI) that one can place on the mud and not sink in (not too badly, at least). The wider the tire, the lower the PSI the tire exerts (for a given weight bike and rider) and hence the "muddier" the mud the tire can handle.

comment Are single-sided forks a gimmick?
@mattnz - Among other things, the auto axle is balanced by the axle on the other side. And the auto suspension is actually DESIGNED to "bend" (camber) as it compresses, to maintain the desired geometry.

Nah, you should be using Objective-C.

comment My crankset stops the pedals from turning when I tighten it onto the bottom bracket
You're question is unclear. When you tighten the crank arm onto the shaft can you tell what, if anything, is binding? It kinda looks like the crank arm and BB cup are designed to "nest" to produce a seal. Do they indeed seem to "nest"? Why did you take the crank arm off, and what have you done to the BB bearings since taking the arm off?
