Having stalled on my build I have now reached a stage of fitting the crankset and setting up the drive.
I'm using Suntour XC Microdrive gear. My seat tube measures 35mm and I currently have a 115mm bottom bracket fitted. This makes the chainline to the middle ring 47.5mm.
Can anyone with experience setting up Suntour Microdrive stuff tell me whether 47.5mm is OK or whether I should change the BB to aim for 50mm?
Also for a 3x7 set up, what (modern) chain should I go for? I've heard I need a thinner chain, so perhaps 9 speed KMC?
