comment How to select gearing for descent?
The idea is not that you can go faster through an 1/4 turn in a difficult gear, but that you will be in a better position to recover is case of surprise.

comment How to select gearing for descent?
@Blam, you are tearing down, trying to evade BB-hight size stones. Pedals are level, twisted at each stone to put the crank, that is close to the stone, up. Then you have several meters of cleaner singletrack, followed by another set of obstacles or a turn. Do you risk a full turn of the cranks? If the gear is difficult, you can make a 1/4 turn and still be around horizontal, ready for turns or impact avoidance. Or maybe my description is just stupid :D

comment how to translate MTB wheel specifications?
@DWGKNZ, but it is confusing. Things should get measured and specifically checked, not 'assumed'. Heck, I purchased a complete groupset and the FD didn't fit the build!

To clarify, this question is about shifting. Selecting gear ranges of components is a function of the intended uses of the bike and out of scope here.

Aaand we have 148mm rear length.

Why is this answer downvoted? IMHO this is the best answer to the question so far, the other one recommending to 'assume' things.

comment Why the solid 12mm rear axle?
I can only speculate than in 2-3 years time the industry will "invent" the hollow rear axle. However, I have faith that the bike market competative, at least when hubs and frames are concerned!

comment Why is it important to keep equal number of turns when building a wheel?
Indeed. Whatever, this seems to be a complex issue, not easily solved by someone on the internet. Probably because the sensor (me) is a source of noisy and incorrect information. I'll post if I learn more about this discrepancy.

So, in theory, if the rim I start from is wrapped, but the spokes are the correct length, following the rule of equal turns should actually straighten up the rim (in the perfect case making subsequent truing of the wheel unnecessary)?

comment Why is it important to keep equal number of turns when building a wheel?
@Blam, no I stopped after some spokes got really tight (tighter than on another, quality wheel) and just made the tension on all spokes equal, without regard to number of turns. This included tightening some spokes 3-4 full turns. I will bring the bike to a mechanic and ask them what they think over a beer. Thanks guys!

@Blam, a sane conjecture, but it conflicts the "thread all spokes until just no more thread is visible, from there on you have no frame of reference, then do equal number of turns". I think I will follow it for the rear wheel!

I did 1) tighten all spokes to within 4 threads showing then 2) tighten all spokes so that threads just disappear then 3) go round the wheel two times doing half a turn on each spoke. The result was some tight spokes, and some wobbling. Both wheels are dished.

@Jahaziel, furthermore, as per Sheldon, one can hammer the leading spokes to bend them at the hub, bit cannot access the trailing spokes on the inside of the wheel. I am confused because both sources (Especially Mike) stress the same number of turns very much. Do a Ctrl+F on his site for "go round 5x doing half turns".

@DanielRHicks, the spokes deviate by sometimes as much as +-1mm from the calculated length, because no one sells 255.7mm spokes.

comment In which orientation should a front wheel be installed?
And remember, looking through the valve hole, one must be able to read the logo on the hub. +1 for the laugh!

comment In which orientation should a front wheel be installed?
That being said, I always put my QRs on the right, because it is most important for me not to interfere with the discs. The rear QR interfering with the RD is a small price to pay for the peace of mind that the QR won't loosen and get into the disc.

comment Is it safe to go over roots at high speed on a cross-country bicyle?
Although at the price level of the bike, a chain guide will be too expensive. Also, the fork will soon (within a couple of months) develop movement in the stanchions, relative to the fork legs. This is normal for Suntour XCM.

A chain guide is another option.

comment How much does number of gears matter for a front derailleur?
That's a great argument why the rear speeds are of no concern whatsoever. Although that thing about the width of the cage and the width of the chain, that Batman talks about...

comment How much does number of gears matter for a front derailleur?
It appears I have been misunderstood. I am asking specifically about will a FD, with different number of gears by specification, from the rest of the system, work and will shift correctly? I am aware there is a bunch of other factors when selecting an FD. I am aware what I mean by 2x10.
