Actually there are more options available on a Dahon than all the other folded Bikes. For instance seatpost. You can use a standard seat post, a Dahon telescopic, a lightweight SPD beam, a Zorin seatpost/pump,a cane creek suspension seat post. There are also vastly more options for wheels, There is also a wide range of brakes,stems,handlebars. Standard rack bags can be fitted and the cick front bag system is widely compactable with other manufacters. Any Dahon dedicated bag?I wish I had a similar choice for my Mezzos!
