I will first admit I am a total biking newbie, so I'm sorry if these are silly questions!
Question 1: If one has a bike with a rear coaster brake, is it possible to just remove the coaster brake without having to disassemble the entire rear wheel? Or would removing the coaster brake meaning having to disassemble it-- ie, take apart the rims, spokes, hubs, etc, then rebuild it again without the coaster brake?
Question 2: If one has a rear wheel already built with a Nexus 8 hub that is roller-brake compatible, but *does not have the roller brake on it*, same question as above: would you have to dismantle the entire wheel to add the rollerbrake, or can it be added without taking the wheel apart?
Please note- I don't have these bikes/wheels so I'm not looking for advice of what makes the best brake/rear wheel/blah blah blah. I'm just trying to figure out how this stuff works and what is the easiest way to go about it, if I DID purchase these items. Thanks!
