I'm a road biker, usually seen lurking in that forum. I just bought a Cannondale F300 to start tackling the trails. It's an 8 speed with Sram X4 shifters and SX5 rear derailler and linear-pull brakes. I know it's a low end drivetrain, but I'm looking for opinions on the frame and general build quality of the bike. Will this bike be enough to go off of low 1-3 foot drops and handle basic trails? Should I bother installing disc brakes, or will my linear-pull brakes be enough for now? Are there any known shortcomings for this bike?
