Ong Chee Ooi,
The Special Blend build from Ibis is spec'd with the X-Fusion Vengeance RC Fork that is in fact 170mm of travel. The geometry for this frameset is based off a 160mm fork, but can accommodate the use of varying fork lengths up to 180mm.
As for shipping to Singapore, unfortunately we are unable to ship Ibis products outside of the United States. According to Ibis' website, there are several distributors in Singapore. The photo attached displays the distributors contact information according to Ibis' website.
