Hi Nanthan,
I will talk with Arnaud about this issue ... Apparently, he has some other locations in Changshu where you can find some bikes supplies ...
Just near the old Auchan on Huanghe Road, there is one shop that Arnaud says lots of good things about ....
We will you join one of our rides by the way ...
With the temperatures rising, we either go up the Yushan hill early morning or in the evening ...
During the weekend, we usually go riding around 10:00 am with a starting point either at Starbucks in Fangta Jie or near the old Auchan on Huanghe road ...
Keep in touch,
Matthieu
