God damn... that is not the way to go... I guess they think people are forced to buy their frame like back in the day when E10 was only one avaible for the diy market. I don't think anyone will be rushing to buy Dengfu these days, especially after these recent events.
I had a problem with my LCE971 rear triangle recently. Little bit over a month ago I did some work on the routing and noticed the gear shift cable housing had a slight damage. It was quite small so I didn't think much of it.
However... I recently chose to upgrade to Shimano XT linkglide (from Microshift Advent 9-speed). The Microshift is truly earned their name as extremely durable. The rear derailleur took few massive hits and got pulled into the cassette twice. After these hits to the derailleur I was still able to ride the bike home instead of having to carry it. It even shifted some of the gears! My friend who was with me then said that if that happened to his gx there was no way it would have worked again. I rode the microshift months but this last damage to it was too much and couldn't be repaired. Got a great deal on XT linkglide (cassette, derailleur, chain, shifter) and chose to upgrade to it.
When I was doing the switch I wanted to check on the cable housing and this time it was in horrible condition. The damaged cable housing was in the front part of the rear triangle.

I contacted Jim about it and let him know I will be taking a look inside when I will get hands on a borescope. The inside was really nice looking and smooth except were the cable damage was located. There were some defects from manifacturing process. I took photos of that and sent them to Jim.
After 8 hours ( guess the work time in China) I received a message from Jim saying they will make a new rear triangle for me. Though it will take some time since they are still working on the new version. For now I will route the cable outside the rear triangle so the bike will remain usable while I wait for the new rear triangle to be done and shipped. Lightcarbon proving once again that they are a serious brand and they stand behind their product.
