While i was out of town, my Dahon Speed P8 developed on the rear tire.
The leak was on the rim side and was caused by a burr or a piece of
metal flake on the spoke hole.
This bothers me for 2 reasons, first the manufacture of the rim did not
bother to de-burr the drilled hole and second, that the rim liner was
of poor quality, insufficient size and poor installation. the rim liner was
a cheap plastic liner that did NOT cover the spoke holes properly.
The fix was easy, I simply removed the old liner, de-burred the holes
and installed a duck-tape derrived rim liner.
It's really not a huge problem but I pisses me off that something so simple
was neglected on this bike.
My Vitesse D5 arrived with rims so out of true, so I trued them myself on a wheel stand. I immediately realized that some spokes were badly turned and the nipples worn out, before I touched them! So I had to use different sizes of nipple wrenches to grab the unworn part to turn the spoke. I'm not very impressed by the way my bike was assembled when I opened the box. In a few weeks I can learn all the skills to start a Dahon service shop... thanks to all the annoying problems! (Ok, the problem wasn't just rims... brakes were badly misadjusted, and so was the gear shifter cable. Then screws fell off from the seatpost pump and magnetix...)
