No, it will not be possible to run a 24" whel on the adamant a1 frames... 116mm spaced frames require narrower spaced hubs. (mountainbike hubs are 135mm spacing) The 116 mm frames use snail cams/chain tugs which takes care of the chain tension and dont break when yu land on them... However...The 135mm spaced frames are also able to run a singlespeed gearing but also offer the choice to switch to gears if desired. But, the tensioner used is vulnerable to knocks and breaks easily... If you are going to stick with single speed set up, obviously get the Modstock. Any further questions? Its 4am and im the only sad ass up with a can of coke replying on here...
