Why We Like The Vision Metron 5D ACR 3K Integrated Handlebar

The Vision Metron 5D ACR 3K Integrated Handlebar provides superior aerodynamics to our road setup with its wing-like shape of the bar top. The new ACR system keeps all cables, wires, and hoses routed internally for a clean look and extra speed and is also compatible with Di2 systems. The ergonomic design ensures riding comfort, using a slight rise from the stem clamp, a 5mm offset, and a 10-degree forward bend to place our arms in the best riding position possible.

Carbon Fiber Delamination

I've used it once or twice and have initial impressions

Shortly after completing the installation, the top layer of carbon fiber began to delaminate on the top cap. A small crack is also beginning to appear by the bolt hole. I use torque wrenches and everything was done to spec. The conundrum is: to send this back to CC involves new bar tape, a double brake bleed and re-wiring the replacement. In short, a huge hassle. Thus, I'd rather just get a new top cap, but they aren't available anywhere! Given how expensive this bar is and how ubiquitous a traditional top caps are, FSA should have a ton of these on hand. I haven't reached out to FSA yet (have to wait until Monday) but if they don't have a satisfactory solution, I'll have to send the whole thing back. Again, given the cost of this item, I expected much better.
