I am riding a Giant Talon 1 29er and I am a complete rookie to mtn biking. Giant gives you the crappiest most general manual not at all related to a specific bike. So I was playing with the shocks, one side has a lock which i figured locks the suspension, but the other has a preload which no matter where its turned seems to feel the same. So how can I set up the suspension so it has minimal travel or takes a lot of effort to make it move since I am a heavier guy?
