Gears...again

Long time no posts. I put my gears back on today, considering I'm the technically inept half of TSS I think I did an OK job for my first time. Instead of limiting the derailleur the classic way, with the limit screws, I used the shifter to limit the derailleur. Say 1 is the hardest gear and 9 is the easiest...I only run 5 gears so I only want the derailleur to move from 1-5, or rather 5-1, in terms of cable tension. So I set my shifter to be in gear 9, all of the cable slack pulled in, and mated it to the derailleur which was sittin' at 5. Done.

Three noteworthy things...It doesn't shift very accurately, although I have yet to ride it. This is probably a combination of an old, still kinda rusty, cheap cassette, and my mostly nonexistent mechanical skills. The derailleur I'm running (thanks Rob), a shortcage 20th anniversary X.0, is bent (courtesy Mr. Fraser racing Worlds DH on it), so I remedied that by throwing a washer from my female axle between the hanger and the derailleur. The derailleur still makes all vital contact with the hanger, and it'll finally reach the 11t. Perfect. Finally, the one issue NOT related to the cheapness of my set-up (derailleur + cassette....$30) involves the b-tension adjustment. When it's dialled into an optimum position, the cage rides the dropout a bit. I suspect this has a bit to do with my frame, which is mostly intended for singlespeed use, and a bit to do with the afore-mentioned washer, bumping the derailleur out by a few mm. I'll see how it affects things while riding.
