Retro Kona Cinder Cone Bike Frame. 1993 Model with double butted steel tubeset; to my mind the best year for retro Kona’s. It was the first year to get serious about weight saving and had the nicest two colour fade paint jobs. This was the same frame as on the Lava Dome (the cinder cone was specced and priced higher). Signs of the years and age. Rusty in places but structurally sound. No cracks or dents.

It has been stripped and repainted with aerosol. The finish is good, but there are areas that are not perfect (see photos). It has been primers and had 2 coats of color, then new decals applied. It comes with a new and complete headset and a nice retro quick release seatpost clamp. The bottom bracket threads are mint, and the sliding dropouts are in equally good condition. There are no dents, scrapes, or cracks. I’m not sure of the size, but the dimensions are. 15.5 inches from centre of bottom bracket to top of seat tube. 22 inches from centre of seat tube to centre of headtube. Straight 1 1/8 steerer. 34mm external cup headset. 68mm bottom bracket shell width. 26″ or 24″ wheel. QR or bolted axle. It was painted and built up into a complete bike, displayed then stripped for parts. There are a few tiny chips to the paint here and there. I have taken detailed photos to show the condition so please study them before purchasing. Please have a good look at the photos before purchasing and check out my other retro bicycle components listed.

1998 GT Tempest MTB frame in gold. 20 inch frame so size large, would suit people around 6 ft tall. In good structural condition, ie: no cracks or dents as I could see. Cosmetically challenged, paint is flat in places, signs of chain rash on chain stay, heel rub, tyre rub, cable rub, basically all the rubs, stone chips, scratches etc… Prime candidate for a respray and new decals, or just build it up and ride it.

There is a small dent on the top tube, which is shown in the photos. It is very minor and doesn’t affect the integrity of the frame whatsoever. There are the usual scuffs and marks from usage but still in good condition and fully functional. All the pivots are tight and moving smoothly with no play. The bottom bracket threads are mint as is the rear mech hanger and thread. The Manitou Swinger 3 way air shock is in great shape with no leaks, and the stanchion has no wear or scratches. The seal has no cracks or perishing and it holds sir. The rebound adjuster is working as it should. Frame size is MEDIUM and the dimensions are. 17 inches from centre of bottom bracket to top of seat tube. 22 inches from centre of seat tube to centre of headtube. 49mm external headset cup diameter. 68mm bottom bracket shell width. It is a very nice quality frame, and it would build a great bike. Please have a good look at the photos before purchasing and check out my other retro bicycle components listed.
