Nice..

You might want to mention that a required tool is a cable cutter, especially with derailleur cable housing. One can , in a pinch, use basic wire cutters on brake cable housing as that is a solid metal spiral sheath, but der. cable housing is sheathed with a metal bead which will get completely crushed and mangled with basic wire cutters.    

Also, the b-tension screw has different recommended settings based on whether it is Shimano or SRAM as the new SRAM der. have a different guide on how to set the gap between the upper pulley and the biggest (lowest gear) cog.

The sentence construction and punctuation in this article is so bad that it even changes the meaning from what the writer intended in some places.  The writer even needs to review the differences between "to" and "too," "it's" and "its," stop using comma splices, etc..

I would recommend using Park Tool's online articles instead.  Their article on adjusting the rear derailleur is at http://www.parktool.com/repair/readhowto.asp?id=64 with lots of pictures and better writing.  You can also refer to the manufacturer's instructions which may differ slightly.  Shimano has all their component installation sheets in .pdf files you can download.  Concerning the H screw adjustment, neither article agrees with how Shimano says to do it, which is to make the pulley line up with the outer line of the small cog, instead of centering it on the small cog.  This is important to get quick shifts to the small cog.  You don't have to worry about it going  past the small cog and letting the chain come off.

I just scanned the copy quick and there were two errors on the use of to in the copy. Which you are right, is two too many.

That said, I recommend using both articles. The park tools one is written well and offers one writers perspective on how to attack the adjustment. Ours offers another.

Fortunately since it's not like 10,000 magazines have already been printed, it can be corrected even now after it has been posted.

One of the things that desperately needs fixing is this one:  "Screw the b-tension screw in to get more clearance loosen it to tighten the gap, the closer the pulley comes without touching the more precise the shift will be."  The first time I read it, I saw the words, "to get more clearance loosen it," which is backwards.  I had to read it a few times to figure out that it should have said, "Screw the b-tension screw in to get more clearance, or unscrew it to tighten the gap.  The closer the pulley comes without touching, the more precise the shift will be."

It was confusing where it said, "If it does not far enough..." with the word "go" missing before the word "far."  When I first saw "White grease" (with "White" capitalized), I thought it was a brand name, as if perhaps from Peter White (like Phil Wood), then decided it probably should say "white" (not capitalized), just indicating the color.

Several sentences lack the period at the end.  The blank line that is required in block style is there sometimes, but it's not consistent.

I hope this seems genuine because I truly do mean it that way, thanks for the input on the article.

I'll give it a run through tomorrow morning and try to correct all the little grammatical and formatting errors that take away from it's quality.

I realize that it's not exactly as in depth in areas as the park tools tutorial is- but for something created in a few hours and still undergoing some pretty drastic editing and additions (with help from people like you guys)- we hope it'll be a go to source for many people.

Again thanks for the input.

I would agree that a little more is needed about cable housings.  You do need to replace it sometimes, and cutting it is not a trivial task.  For the record, I use a Dremel tool with a metal cutting blade.  It cuts fast, easily, and neatly.
