Sliding rear dropouts, with a derailleur hanger and disc mounts, are used on the Explosif making the conversion to a single-speed simple.  For those who prefer a gear cluster the cable routing is in place and has been moved to the top of the top-tube for smooth shifting. 

Bikeman applauds Kona again for their continued use of steel tubing. The Explosif frame uses the same shaped and butted tubeset of the Unit 2-9. For strength, durability and ride quality there is no better material than good ole' fashion steel. The Explosif 2-9 also incorperates the oversize chainstay yoke from the Unit 2-9.

Kona's mountain bike heritage fit perfectly into the 29" market segment.  The use of a high end steel tubeset and the functionality of sliding rear drops will make the Explosif 2-9 an instant hit.  There are rumors of a 29" Project 2 fork coming from the great folks at Kona.  No definitive word on this yet but we will keep you posted.
