Hi All,

I'm currently riding an early to mid 80's classic steel Specialized Allez. It's an awesome bike, but I ride in a hilly area so I'm looking to put a bigger freewheel on the rear. Currently, I have a 7 speed freewheel with the largest cog being 24 teeth with a Shimano 600 short cage rear derailer and a double chain on the front. Does anybody know what the largest rear cog is that you can use with the Shimano 600 short cage derailer from the mid 80's. I tried to find the info on Shimano's web page but I couldn't locate any info on the older Shimano components. Thanks.

Roland
