Converting to Compact Double?

[Popoki_Nui]

I recently converted my Bianchi Limited to a MTB triple (48/38/28). I was able to simply change out the old BB for a new XT cartridge as the original was worn out anyway, and the XT crankset bolted right on. The spindle length was same as, and the chainline is perfect.
The stock Shimano 600 front derailleur works perfectly (just needed to adjust the limiting screws), but I did change the rear derailleur to a Shimano 700CX as the 600 cage didn't have quite the length needed. The conversion went much easier than I anticipated. Cost: $50 for the BB, $60 for the rear derailleur. I had the cranks already. About an hour's work start to finish including adjustments.
Then for fun, I added MTB flat bars, vintage XT brake levers, and fatter all-terrain tires. Now it's a lightweight go-almost-anywhere ride that I really enjoy.
