So with all this Hub and freewheel talk, I pull the Rear wheel to see what name was stamped on it. It's a SunRace Co LTD. Never heard of them. So looked them up on the web and find little. Do see that they have been in business from 2006 to now. The Freewheel looks like a copy of the IRD freewheel with ramped geras for easy shifting. The Freewheel has the fellowing geras 13/15/17/19/21/24/28. So this time around they put a little more range on it. The blue one had the Falcon 14/16/18/20/22/24/28.
