Ni hao,
I have a Shineray XY200GY-7, aka Long march. +7000 km on it so far, no real problems except build quality, but still much worse than Japanese bikes; it still in one piece.
The major problem is the seat, it's really uncomfortable for rides lasting more than 30minutes. The seat is too soft, and the fabric is smooth unlike modern touring seats; small round grooves that help keep the temperature down and protect the family jewels.
Last week i found a parts market in Kunming, just outside the second ring. I did not find any Shineray dealers, but I found an seat that fits from Jialing. Anyone has such a seat? You find it comfortable? If you had to buy a replacement, where did you buy it ?
I'm also considering finding a carpenter to change the filling to something harder
the ugly seat

rear clamps

Notice the clamp?

the underside


Any help appreciated,
Thanks
