comment How to get more tire clearance with caliper brakes?
From the picture it looks like the pads are not sufficiently curved to match the curvature of your wheel diameter. This could be half your problem. Find pads that are more curved.

comment Why isn't my suspension bouncy?
@Jahaziel Seat post supension has the feature that it goes away when you stand on the pedals, leaving only the front suspension. This can be regarded as an advantage. It may be ideal for the user who does mostly road work, and little or no downhill trails.

comment Why isn't my suspension bouncy?
A suspension spring does not return at the same rate as it is displaced: the unsprung mass (wheel plus lower part of the suspension) moves the spring quickly under the sudden impulse of the road irregularity. The spring then moves slowly, since it has to move the much greater sprung mass! Damping is about reducing overshoot, and diminishing the oscillations. Without any damping at all, the suspension is a harmonic oscillator whose oscillations store energy. Shocks are absorbed fine, but the oscillations grow in amplitude as the effect of the shocks accumulates.

What is Mm? mega-meter? So 20 Mm is 20,000 Km?

comment 29" freewheel ruined (slipping)
This question is ineffective without added information: age and history of the bike (how many miles on the chain?), and close-up pictures of the drive train.

comment How to lubricate cables?
WD-40 contains lubricant. According to the MSDS it contains "petroleum base oil". Not a lot of it, but it's there. You can see it. Spray the stuff on a surface, let it evaporate and there is a film of oil. This oil is not suitable for every purpose; it works in those situations that call for a light machine oil. There is also no mention of any useful additives (anti-rust, anti-wear). So it's not a great lubricant and its claims of being general-purpose are greatly overstated; but it's a lie to deny that it's a lubricant.

comment How to lubricate cables?
This is something generic put into a container which is labeled as being created specifically for non-coated cables. The idea that you need a myriad of separate lubes for every conceivable purpose is just clever marketing.

comment Can I increase my highest gear ratio?
I have 48-11 on a bike with 24" wheels. I can still mash up some hills in that gear and into some headwind. It is not that high. (It seemed high initially, but from regular use, the thighs beefed up.) I can easily see that 48-12 would be perceived as not high enough on 26" or 27" wheels.

comment Can I increase my highest gear ratio?
12 over 11 is a 9.1% increase; it's not a lot, but it's significant. The 18.2% difference between 13 and 11 is huge; half of huge is still something.

comment Chain “vibrates” on higher gears
I had a grinding sound caused by the chain (when on the smallest sprocket) rubbing against the special nut which takes the bolt that secures the derailleur hanger (lugnut-mounted style) into the dropout. The nut is thin, round disc, with a thicker tongue part on one side which mates into the dropout. But with the wide freewheel I was using, which provides a small cog (11 tooth), the chain was coming into contact with the disc, causing rumbling. The fix was to file it down the disc a little bit, focusing on the edge that was catching the chain.

Shorten.

comment Does this chainring need to be replaced?
Note how you're not filing anything on the opposite edge of the tooth, which has a decently shaped profile for meshing with the chain rollers. Maybe you could save yourself a ton of labor simply by reversing the worn ring left to right.

comment How to measure chainring / cog wear?
You probably got downvoted for not answering the question at all, which is very clearly about measuring the tooth wear of sprockets, not about measuring chains, or other methods of scheduling drive component replacement. Also, "wait for it to skip" is the sort of approach you may be able to specifically avoid by inspecting and measuring. Your first chain slip may occur in a situation when it is inconvenient to tend bike maintenance, like in the middle of a trek.

comment Chain skipping on new freewheel and chain setup - What went wrong?
I have a comment in addition to my answer and it is this: 11-32 is a ridiculous gear spread. Not all derailleurs will handle this range very well. The large sprocket means that your chain has to be quite slack if you want to engage that sprocket and your largest chain ring, and the derailleur has to pick up all that slack to be able to also engage the smallest ring and smallest sprocket without pulley clash. You do not need this. If you're on a hill where you feel you have to engage the 34 together with your smallest chain ring in the front, you might as well get off the bike and walk it.

comment Chain skipping on new freewheel and chain setup - What went wrong?
The fact that the skipping occurs less on the chainring is also a consequence of there being less leverage on the large chainring resulting in less chain tension. The jockey wheel will also droop more when the chain is on the smaller rings, resulting in less chain wrap. My POS bike has the original rings on it which are probably 10 years old, and show considerable wear: there is no skip/skip in the system after proper derailleur tweaks.
