I commissioned the part from a guy called "Mario Ti" a representative of spartsti.com through facebook. They have many 3D scans in their library and can make custom covers to match many frames/stems. Still not cheap at 35USD but nicer quality than the FSA one, and custom stack available too.

[img]Decided to go with this bar after months of deliberating about which one piece bar to choose. The ergonomics on this bar are seemingly perfect to me, I was looking for something most similar to an Enve Pro Bar without spendeing 1200$. Also at 352g they are not light but I wanted similar durability&stiffness as the big brands so I figured with Peter marketing them as extra stiff that was what I wanted.
They were super easy to route, much easier than the Tavelo bars, I had to get a 3D printed SL8 to FSA ACR headset adapter but I don't mind cause I was able to source a very high quality SLS printed model since ACR is so popular.
Overall after a few weeks of riding I'm very happy with the stiffness and ride feel, vey trustworthy product so far and I'm looking forward to getting more of Peter's products soon.
