Trek's goal was simple: Build the lightest production road bike possible. That's where simple ended. Conventional thought was stripped away, every frame detail analyzed and every frame size tested. And then re-analyzed and retested. The road has been long and we proudly present to you the Emonda—a groundbreaking road bike you must come ride!
Simple Rear-Derailleur Adjustment - Here's a simple way to fine-tune rear shifting. You don't even need tools. Look at the point where the cable enters the rear derailleur. See that round knurled piece? That's a barrel adjuster. Standing behind the bike, this adjuster is turned in half-turn increments until the shifting glitch is cured. Which way do you turn it? It depends on what's wrong. The most common problem is slow shifting into easier gears. But, you might also be experiencing the opposite. Follow these rules: If the derailleur hesitates shifting toward the spokes, turn the barrel toward the spokes (counter-clockwise); and if it hesitates shifting away from the spokes, turn the adjuster away (clockwise) from the spokes. (Always turn it only a half turn, check the adjustment, and repeat as needed to cure the problem.)
