Kimbell Jaya used to have one in the shop but due to it's unpopularity, it was there for very long and it was offered away. Maybe you can call Jimmy at 012 292 7636 and check with him if he order one for you. 

i was looking at fx13 to but no stock so i got a java fit instead

Finally I saw one in BBS. He's selling a bit near to the selling price though.

Inner tubes is one item that is not standardized. They marked the price in the event they need to provide services to change the tubes too so usually they charge RM15 regardless. If you know a LBS or familiarize with them, they can sell you for RM12 or even RM10 each. Also they depend on the brands and also the material it is made of, mainly butyl rubber or normal. Butyl rubber holds air longer than the usual but the usual is cheaper in price. Off course branding also makes them cheaper or more expensive. Maxxis and Schwalbe is more expensive because they are made thinner , hence lighter. Vee rubbers are actually very good inner tubes and cheap too but not many LBS stocks them. They are thicker and a tad heavier but they really hold air long. 

Schwalbes sell inner tubes at RM29  What advantage over Maxxis which are sold at RM16, I can't see the difference except the valve cap is transparent.
