got the dirt bug lately, so I converted my older GF mamba hardtail into a SS. Real getto style, took apart a few extra cassettes had laying around to use the plastic spacers and the cog. Not bad for not having to buy anything but a chain. Got lucky with the gearing, didn't need a chain tensioner, but have a sigulater if I decide to change anything. Gearing is 38/18. Chainring is a circa '89 Cheese chainring bolted to a early XTR crankset. need better pedals and saddle, but rides nice for around town and some steep hills. What do you think
