The original Gtek was the first Eclipse marker to bare the now-iconic Gamma Core drivetrain. Efficient. Smooth. Quiet. Gentle on even the most fragile paint. And reliable beyond comprehension. From frozen wastelands to scorched earth deserts the Gamma Core delivers all of its potential, all of the time. So the decision to continue with the Gamma Core in this, the Second Generation of Gtek was a simple one. A no-brainer. But that didn't mean the rest of the marker wouldn't see a serious overhaul. The 170R combines a raft of advanced features to bring the Gtek line bang up to date.
