Control Tech ONE ±5° Stem by Controltech covers the whole road market, from serious racers to weekend warriors, and everyone in between: all can ride with perfect control

Controltech products address the three biggest issues first: low weight, for the fastest responses and superior performance; high stiffness, for the most efficient power transfer and accurate handling; and engineered-in compliance, to reduce rider fatigue and increase comfort. In fact, our superlight road components are so strong and rugged they’re suitable for cyclocross use too.
