|So I am still working on getting the downtube shifters off my girlfriend's 6 speed Cannodale. It is equiped all around with Shimano 105 (late 80's - SLR - single pivot brake - biopace - index rear).
1) I found a bolt on 7 spd freewheel that will work -- only it is 38T. This is good considering she has a double and struggles on hills but can a 80's era 105 r-d handle this big of a gear?
2) If I can swap to 7 speeds then I can go with the Sora STI levers for around $100 putting the shifting on the bar where she would like. So another question I have is will the Sora STI work with a non-STI f-d or will I have to repalce that?
What are you thought? I know barcons are what comes to everyones mind but she really doens't care for them. I also showed her the Kelly converters and she didn't go for that either. Thanks.

|1)now all you hav to do is find a RD to shift it.2)The freewheel has to have the right cog spacing, and with a doulbe crankset you might get away with the old derailer....Get another GF that is more appreciative, less picky, AND lower maintenance.|

|My bad. 28T not 38T. LOL.
Do you think the 105 r-d would work with a 28T instead of the earlier suggested MEGA number.

|I run a 13-28 cogset on my 8 speed, with a 39-53 double up front. The derailuer is a normal short cage rx-100. Shifting quality is very good. The chain slack in some small-small crossgears is noticable on rough surfaces, but at that point its time to shift to the big ring anyhow.|| |
