ControlTech CLS A/Head 6061 Road Stem 31.8mm

3D forged 6061 aluminum stem that meets a 6061 faceplate for a secure cockpit.

Product Details 

• Rock-solid stem and faceplate made from 3D forged 6061 aluminium, a combination proven to increase strength and reduce weight
• The ‘forged’ method of manufacturing is significantly stronger than ‘cast’ but requires less material, resulting in a stiffer and lighter stem
• Because correct stem length is vital for a comfortable bike position and good handling, the CLS stem comes in various sizes
• Easily flips to give a 5° rise or drop depending on your aerodynamic ambitions
• SCM-435 steel bolts adds further strength while providing a secure fit
• Fits 28.6mm steerers and 31.8mm bar clamps
• Weighs 110g (100mm)
