changing chainring and gear adjustment?
Hi,
I'm getting a 36T 116 BCD chainring in the mail today to replace the 42 chainring on my double. Do you think I'll be able to ride it as is or do you think I'll have to take it to the bike shop for a gear adjustment.

How big is your outer ring? If it is a 52, you may have to upshift the front derailleur a little more slowly and carefully. Also, in the small-small combinations, your chain will sag a bit if your derailleur cannot take up the additional slack. Neither of these problems requires any derailleur adjustment, other than perhaps tightening the pivot positioning screw, to rotate an older derailleur clockwise (downward and backward, thereby increasing chain tension).
I used to gear my Nishiki 50-47 / 14-16-18-20-23 (half-step), which I changed to 50-42 / 14-23 (Alpine or 1.5-step) on days I planned to ride through the hills of west-central Los Angeles or Malibu/Topanga. The gearing change entailed simply swapping the inner chainring, a 5-minute operation.
