I somewhat hijacked another posters question, on an earlier post. Most answers were directed at his initial question (as it should be). I did reread some old posts and look at the answers he got, looked around the web a bit more and have formulated a rough plan.
My bike presently has the 105 group, on my 1987 Schwinn Tempo. Gearing is 52/38-13/24.
My thinking is that I have these options.
Change front crank to either a triple or a compact double.
Broaden the range on the rear freewheel.
Looks like I will need a wider range RD to accomplish either of these options. Im thinking I would prefer the compact double over the triple. I am thinking of changing out the freewheel first, and then moving to the cranks if I find it neccasary. This will involve just an initial change in freewheel and RD.
Im looking at a RD that will accomodate a 16t front change, a max cog of 34 on the back with a total tooth capacity of 36t.
So Im thinking my initial purchases to be something like the following.
Using the 14/28 or the mega range 14/34 (this seems a bit odd, but if it shifts fine maybe a nice bailout?)
This takes me from a current low of 42.4 Gear inches, to a low of either 36.3 with the 28 or 29.9 with the 34. A final change to a compact double gets me to 26.8.
First stage can be done for about $60 dollars, so it seems a pretty decent change for the money, while letting me keep my index shifting intact and not worrying about frame issues of going to the newer 8-10 cog cassettes.
So a reasonble plan? Short sighted, better alternatives?
