Kona Hei Hei frame size swap

[giraffeinbath]

Hi,

I have a Kona Hei Hei frame circa '97 that measures as an 18" in the seat tube but has a different geometry (shorter in the top tube) than the '91 Kona Lava Dome that started me on my bicycle journey.

If anyone has a '91 standard geometry bike they would be willing to swap for my '97 just give me a shout.

Thanks,

Gareth
