The Apex is the lightest stem here, at 120g. Its twin wraparound clamps need to be slid on from the side rather than clipped straight on, but this was never a problem, even with non-Renthal bars. The six-degree rise/ drop adds bar height options. Despite the narrow bar clamp, it feels stiff enough.
Care is needed when fitting. It’s essential to grease the bolts and tighten them to exactly 5Nm (the max recommended torque) to avoid it twisting on the steerer. Even then, we’ve had it twist slightly when riding hard.
