I'm looking at the LHT and want to know if anyone out there has changed the stock chainrings for anything different. I see the complete bike is equipped with a 48-36-26 in front. How will that combo work for all around riding with the back cassette which is 11-13-15-17-20-26-30-34 ? I know this would work fine for my 7 mile commute which is flat but living in the PNW its not far to hills if you are going to do any kind of longer rides. I'm pretty clueless about different gearing so excuse me if this is a really basic thing I should know.
