After a rather informative post in the Commuters section, I've come to the conclusion that I have to swap my crank & chainset which is basically a mountain-bike setup to set which suits my riding style.
My current crank/chainset has three gears, largest being 42t, and is connected to a square-tapered Shimano UN26 B/B with 113m/68m dimensions. After a quick talk with a LBS, he said there was a direct swap by Shimano (Deodore series) that would fit my bottom bracket and was geared 48-38-28 which is ideal for my use. What he didn't mention was the model/type. Please keep in mind that my bike has a 8-speed cassette with 11-30 gearing.
