There has been a turn of events! Pour a dram, stoke the fire, hunker down and listen brothers!
I found a cheapo spindle on ebay from khe that claims to be 150mm, which should correspond to around 5.9 inches right? Nearly the magic number 6. I got the spindle and a cheapo 4130 crankset for 50 euro, bought a 73mm euro bb from dartmoor for 50 euro.. Full setup for 100 euro! Let's pray that it'll be wide enough, what do you guys reckon? It's not quite 6 inches, like 3mm less.
