Dahon Jack bike review

Dahon produced the Jack bike in 2009 and can be classified as a Folding bicycle.
Jack bike is available in many sizes such as Small , medium and large .
Dahon Folding Jack can be found in one single color which is Shadow.
This bike is equiped with 26 x 2.00" Schwalbe Big Apple tires and Stainless spoke wheel while the rims are manufactured by Aluminum. Dahon equiped this exact model with ProMax linear-pull brakes, Promax alloy levers braking system and Front: Formula aluminum, Q/R, Rear: Formula aluminum cassette, Q/R hubs.
To guarantee the comfiest ride Dahon used 7005 aluminum material for the frame. 6061 aluminum riser high strength material is used on the handlebar of this Jack to ensure the perfect handling while the stems are made of Dahon F.I.T.
For the smoothest biking experience TruVativ ISO-Flow 1.0 G, 36 teeth is used on this bicycle linked to KMC Z50 chain that is easily replaceable as stated by Dahon, the whole system is connected to a high reliability SRAM 3.0 Comp gear shift levers.
