He's 5'10 so I'm thinking medium would fit. We're not looking for anything fancy since hes just going to start and learn. Basically as cheap as possible but still quality bike.
Medium/17" Fisher Paragon 29er. Currently set up single speed with surly singulator. 32-20 gearing. Bike is in nice condition. $ 350 as pictured, for an extra $50 I'll swap in a 90mm Thompson stem, and a Thompson post, if nobody buys 'em first.
