I am looking at this bike to use as a road bike/light touring perhaps. It has ultegra rear derailleurs, tiagra in the front, cassette is HG50 9s 13-25T, crankset= FSA vero Powerdrive 50/34T, tiagra front and back shifters, tektro r310 duaal pivot with adjustable angle brakes.
I would probably be carrying 20lbs if I was to go touring on it, and it has eyelets. Would it be okay though in the mountains with 20lbs attached (the cassette)?

Or should I spend a bit more and get the Silverstone Sl4?


Thanks!
