Would a nexus hub be the same width as my current hub + gears? My bike's a 2004 Giant Cypress so I would assume it has the current standard width hub, whatever that might be. I'm slowly morphing it into my "winter" bike (as winter approaches... I'm hoping to buy a new good-weather-bike next spring). One thing that might be nice would be the internal hub rather than the rear gear set I have now. That way I still have gear change ability even if the bike gets iced up.
