Cheers Nev, feeling the Kona love. I've got a Muni Mula built up as my polo bike too but can't seem to find a photo.
Sadly had to change a couple of bits on the Fire Mountain (cranks and saddle were shot), apart from that it's all original. I'm running it as a 7 speed currently as it's just for around town use.
Will check out the Tubus racks.
Nice!
This is what I'd go for, but it's a bit pricey.
