Been riding my Chiner for 6 weeks now and it is great. I've had a couple of wrecks, but nothing serious (for the bike anyway). I mis-judged a log and planted my front wheel right in front of it rather than on top. The bike stopped, and I wound up flat on my face. The other was on some tight singletrack where I got careless and clipped a small tree with the end of the handlebars. I wound up with a sprained thumb when I hit the ground, but the bike was fine.
I think I solved the shudder/judder issue with the front brake- it seems to have been caused by the headset not being tight enough, even though I thought I torqued it down pretty good. The Neco expanding plug may have been slipping and thus not tightening as much as I thought- there were marks in the steer tube where I originally had it, but I don't know if that happened during installation or in use. When I put it back together I torqued the plug and the top cap to 15 - 20 Nm, but the headset never felt like it was binding. With it tighter, I have not had the 'shudder' on the last few rides. I'm debating just putting in the star nut- the Neco plug is easier, but I'm still not convinced that the plug didn't slide up the steer tube leading to too much play.
I still need to shorten the front brake line (I have it taped to the rear der cable to keep it from flapping around), but that seems to be more cosmetic than a necessity.
Iv'e got the beginning of a downtube design-
I think I need to stretch it a bit more and add some contrasting highlights. I didn't really like the plain outline dragons that a lot of the sticker sites have, but the details on this may not be visible from more than a few feet away. Since you can't see the detail anyway, a simple design may be better- something like this, but in gold and about 12" long.
