comment Weight saving between Sora and 105
@Batman, I can't easily find that information on Shimano's (new and shiny) website. For example, this is my crank. How much does it weight?

comment Determining front & rear derailleur compatibility
I was under the impression that after 9sp Shimano abandoned their "2:1 pull ratio" (trade name, not actually 2:1) and switched to something like SRAM's "1:1" (actually 1.2 : 1 or so).

comment Determining front & rear derailleur compatibility
"The rear derailleur is less complex, only really requiring an equal or greater number of gears than the original" so I can use a 10sp Deore RD on an 8speed setup?

comment Is the Park Tool Allen Wrench going to strip out bolts?
My dirt cheep 5mm has begun loosing it's (nickel) plating after only one year of (ab)use, so I doubt a bit the "lifetime" thing. Maybe 10 years (== lifetime for people who hate helmets).

comment Why no wheels with rope instead of spokes?
Haha, "exploded" view! 1. A possible solution to the catastrophic failure shall the string break is have 2 continuous strings - now there are be different tensions, but the single point of failure is eliminated. 2. Concerning movement of the strings: not sure if this can be engineered, but what if friction is enough to allow the string to move only when being tightened (adjusted) and not during normal riding (excluding hard jumps - there the movement of the string could add to the strength of the wheel).

comment Does there exist optimal damping setting for all terrains?
Somewhat off the point of the question, but digital shocks already exist 1, 2, 3. They even have sensors in the fork, wirelessly transmitting data to the rear shock, for continuous real-time auto-tuning.

Optimal as in absorbs terrain irregularities best, resulting in smoothest (closest to straight line) trajectory of the rider.

Hmmm, so let's ignore pedaling efficiency. The question still remains relevant.

So ... walking will do just fine as well :D (5km/h)

comment Should I be able to 'manually' rotate the headset?
@Blam, whatever, first step is to conduct the experiment outlined above and from there we can work out the cause.

comment Is 11- 34 rear cassette necessary?
I was referring to the cassette, as that is a big piece of steel. And I concur the difference cannot be felt, just wanted to add this for completeness in the "The (only) down side is".

Another drawback is increased weight. Don't get me wrong, I frown at anything below 36 on an MTB.

comment Why/How should I bed in disc brake pads?
By pouring water, you are effectively qunching the rotors. Although I suspect the temperature is not high enough for any noticeable changes.

comment What are the negative consequences of not bedding in disc brakes?
I am still not convinced - forbidding it is the easiest. Likewise, they do not say "tighten your brake caliper bolts to X Nm", they say "have the bike repaired only by an authorized mechanic" (general claim, can look for references if doubted).

comment What are the negative consequences of not bedding in disc brakes?
-1 for "If normal riding achieved that SRAM would not have a specific procedure." : bookofbadarguments.com page 34. For example, it could be that SRAM want to avoid people seriously hurting themselves on their brand-new bike, because they do not know that pads bed in with time. Easiest solution: "do not ride bikes without bedded in pads".

comment Is my bike getting ruined?
To clarify - if you don't lube the chain immediately after washing, it will rust (a couple of hours seem to be enough). I don't have solid sources, but I feel that the oil displaces the water and protects the rollers immediately.

comment Do I really need a magic link or can I just replace the pin on my chain?
This ^ concerning 10sp chains. I have re-used 8sp normal pins without issue. The rule is to never cut the chain in the same place twice.

Shimano provide special pins for connecting their chains. It is claimed that re-using a normal pin will weaken the chain significantly (and I believe them).

Note that palm-forward V and palm-back V are different gestures.

comment Can I install caliper or cantilever brakes on a frame and set of wheels designed for disc brakes?
Maybe he can switch to SS and install a coaster brake, heh.
