Hi Andrew

You could try the bike shops in Ba Trieu near Western Canned Food.

If that fails head to

Add: 51 Doi Can

Mob: 0912-410-562 Mr Trung - no English

He will be able to supply what you want. He is an excellent mechanic.

Ok cool. The bike shops on Ba Trieu have the tubes. A ok so far.

I was offered Vietnamese or Taiwanese tubes... and told that one was of far superior quality (for a small premium)>

Thanks again.

Any time you get a puncture there are guys on the side of the street just sitting on the sidewalk who will repair it for you or put in a new tube. They are generally every two blocks or so and usually have a tire pump sitting at the edge of the footpath on the side of the road to let you know who they are
