I’ve built up three Hongfu 66 frames now, and two 166 disc frames. Good frames in terms of weight and performance. However, they haven’t been without issues. Two frames had headset bearing seats which weren’t quite perfectly round and needed sanding. One frame had a internal layer of carbon which interfered with the rear gear cabling that needed filing (boy did that take some spotting….). On another frame they’d painted over one of the plastic internal cable guides, and on another the rear brake cable guide had a ‘snot’ of carbon which meant the cable ferrule wouldn’t seat properly and again needed filing, then touching up with paint. And finally on a mate’s frame (not one I’d built up) it developed a crack on the seattube near the BB, so they replaced the whole frame under warranty.
So in short, a mixed bag really. I like my own disc roadie (FM-166) – it rides well and I’ve not had any issues with it but I’m not sure I’d recommend one to a friend, and I’d certainly tell them the issues above.
I bought direct from them. Email was good and no problems with that. They can paint them for you.
