I'm selling my Kona Unit single speed. It's been a great winter/mud bike and has been treated accordingly. It was a 2006 model but I bought it new in 2010. I have upgraded and changed a few things, but you can find the original spec online here-
Brown Unit frame, large, 26" wheel version
Marzocchi Bomber 100mm Fork (Kona rigid fork also included)
Front wheel 719 on Pro II
Rear wheel single speed specific
Race Face xc ISIS cranks
Trail rakers 2.1"
Brown Charge Spoon
Front brake Juicy 5, 160mm rotor
Rear brake Avid V
Pick up from Shoreham, or delivered nearby, for £150. I haven't investigated a courier but can get a price if you want.
