Hey I'm looking at basic flat bat road bike for fitness and commuting. A second hand Trek FX that might suit me is available. It's a 1+ hour drive away though. It's running Tektro mechanical dial brakes. I will assume these are superior to traditional rim brakes? Never ridden a mechanical disc bike. A mate says once U get them dialed they work well but U have to dial them regularly? I'm also big at 110kg and my ride to work is though some gravel and dusty roads which rim brakes seem to hate.. Mechanical ok or should I just keep saving for proper hydraulic brakes? The bike is cheap enough at $375.
