Hi,
I bought what I thought was a Kona Caldera.
Looking at it more closely, it has obviously been resprayed - I *think* underneath the paint there is orange/red, which suggests it might be a 1999 Caldera, but I'm not sure what other clues to look for.
Can anybody confirm for me please?
Thanks!

As I said in your post in the --> 1997 » Retro MTB Chat section, it seems that your frame is likely be a 1999 Caldera. The only other options with those Dropouts and that Cable routing are the 1998 and 1999 Explosif, and rather oddly, a 1999 Lava Dome that also had the superior New (Dew) Drop "K" Investment Cast Dropouts - but that seems less likely now after seeing the colour underneath.

These Specifications are from the 1999 Technical Information, and could determine what your frame is, but it will be tricky to measure. After studying the dimensions, I think that you will only be able to eliminate the Explosif by measuring the Down Tube, then the Lava Dome by measuring the Stays, and then only be sure after that by weighing the frame.

Scrape the paint of the underside of the bottom bracket, you should find a readable code.
You then have the year.

You only need the first few characters of it.

If Fairly made it will start F and normally be along the edge of the BB shell.
But Hodaka made and it'll start H and these are across the bottom bracket probably.

Is that the same hodaka that made motorbikes ? I had a hodaka combat wombat in bright pink :lol: bought it for £500 rode it twice down my local quarry and an older guy on a crf450 stopped me and offered me 2grand for it so off it went

It will be, it's the only one that used those dropout. Quality builder (hence they built the Hot's too)
