Shineray / XinYuan X5 review

[modron]

I've noticed before that the bike feels wobbly above 115km/h. It feels really scary so I actually am afraid to ride it above that speed. I thought it might be unbalanced wheel or wheels, so since I will be changing tyres soon, I figured I will check then. I rarely ride above 100km/h so I wasn't bothered much.

Today I've noticed that the bike wobbles more (or it's just my imagination). All the bikes I've ridden before were very stable. You know, when you shake the steering bar at around 80-90 it will give you a wobble and you feel that it pulls you out of that wobble. Shineray, on the other hand feels like it wants to wobble more and I need to intervene. It's really strange.
Thought it might be soft suspension so I wanted to adjust and the front feels like there is no difference whatsoever on softest and hardest setting. Also the adjustment nut is significantly easier to turn on the left side. Rear shock seems OK.

Anybody had a problem like this? Or tried to adjust the forks?
