12 Dukes 650 and Challenger 350 have their own advantages and disadvantages

The first disc brake is different, one BB5 and one BB7, the feel is really different, relatively speaking, BB7 is more labor-saving.

Second: the wheels of 650 and 350 are completely different, and the transmission is also different, one uses the ACER series, and the other uses the level of M430, the most obvious is a 24-speed and a 27-speed, if the 320 and 350 are not improved compared to the 12 models of the 350, the multiple reliefs painted are more expensive than the original 200, why bother to be tender, not to mention that this relief is not seen if you don't look carefully.

This kind of brand goods is really a penny for a penny, and you basically won't buy vinegar if it's expensive.

If you compare the Duke series with the Challenger 350, if you travel for a long distance, I recommend using the Duke series. Although the Challenger series is of a higher grade, the wheel system used in the Challenger 350 is difficult to replace and maintain in time once the spokes have problems, and it will bring unnecessary trouble to travel. The 2012 Duke series has been newly unveiled, the new TFS frame series adopts the design of some Challenger frames, the strength and rigidity are more, and the accessories are also easier to maintain. The spokes are also a Volkswagen model. If you travel, it is more worry-free· If you want to travel in the Challenger series, I personally recommend the 2011 Challenger 300 2012 Challenger 320 Duke series If you travel, I personally recommend the Duke 550 Duke 650 Whether it is a bracket or a clay board, it can be installed, and the frame quality is also relatively good, and it is a good long-distance choice

If it works for you, be prompt.

The two are in different series and are hardly used for comparison. If you have rice, it's better to go to 350, if you're direct, the difference is not very big, depending on what you like, just like it.
