I like Bassspines theory. 8)
My haro/intense downhill bike was called “Stacey’s Mom”.
The fountains of Wayne song was out at the time and that bike had it going on!
” I’m off out to ride Stacey’s Mom” was also quite amusing at the time.
Mate has a GT hardtail he calls Brian, as It’s a Lopes frame.
Not because it’s a very naughty boy.
other than that, well, the road bike is the road bike, the cross bike is the cross bike and the XC bike is the hardtail, the full suss XC bike is the Spesh, the 4x/messing about/jump frame is the little hardtail.
