After all, they work on the same principles and require the same main features. However, the small bells and whistles represent the elements that can take one's experience to the next level. Of course, it does pay off to also look after good materials, a lightweight frame and proper wheels. All in all, doing your homework is the optimal method to ensure you make a good choice.
