Rocky Mountain - Altitude 1993


Retrobike Rider
My tiny 1993 Altitude (18.5") my eldest rides this currently, he out grew every bike I could build him over the winter before he could ride them, and now he's probably out grown this to this winter. being taller than me.
It does mean I might get it back, though no doubt I'll loose my long time green Kona

Time I got this thread and bike sorted.

I accidentally bought this frame with a lucky e-bay bid (from a good chap on the forum too).
I never liked this color back in 1993, I much preferred the yellow/red of the previous years (I had the 1991 model at the time), but this year they dropped the wishbone and made the frame damn light.
But after building this, it's a classy nice colour.

18.5" inch is a touch on the cramped side for me, I might only be of average height but I just prefer the comfort of a larger bike. But for slow, 20mile max gentle bimbles it's fine.

I unfortunately cannot find any of the build pictures other than the one in the garden :-(
I'll just have to strip it one day and make one up, 🤓

It was built mainly with parts I had been collecting for a rainy day (my other 20" still not done rattle can black 93 Altitude).
