1998 Kona Explosif...


Kona Fan
About time I got round to putting up a thread on this, I have had the frame sat around for a while and had been slowly gathering the parts to build it but never fully got going with the project until late last year, subsequently I finished the build a few months back.

Growing up I had always lusted after an Explosif and its this model that ignited my love of Kona's. I picked the frame up on ebay last year and was pleasantly surprised with its condition.. Original factory paint, original decals and only minor chips & scuffs consistent with its age. First job was to clean the frame, polish & give it a couple of coats of Dodo Juice supernatural wax making it easy to clean whilst protecting the paint. I had originally sourced an OEM Z2 Atom Bomb fork and Syncros stem but quickly decided on going the Project two route and imo the Syncros stem is just too chunky for this frame so I sourced a cnc stem on ebay, its a lovely bit of kit but I have no idea of the brand so if anyone recognises it please let me know.

This was always going to built up with a 1x drivetrain, I like the simplicity of a setup like this and a bonus being its cheaper as less parts to source & its Lighter! I liberated a chainring from a sram Force 1x chainset and filed it down slightly so I wouldn't have to run the chainring inboard on the RS3 chainset, I think it suits the overall build well and doesn't look out of place with the theme being OEM+..


When it came to building the bike I had forgotten the mech sourced had an SS cage so instead of purchasing another or trying to find a gs cage I fitted an A2Z extension hanger to allow use of an 11-34t cassette. The extension hanger is subtle and does the job perfectly, I also switched out the original heavy xt lockring for a modern lightweight Ultegra r8000 alloy unit.
