Take advantage of the discounts when you find them, it is an excellent bicycle and apart from the excellent product, they told me that I can request maintenance right there and it is not such a dirty price, it is an affordable price for maintenance.
As they come by size it was perfect excellent quality
2 years with this bike, I am very fond of it and it has been my project, compared to when it was new, only the frame remains, everything else is for high-end parts, highly recommended for a project, when this new one comes with very simple parts for someone who He is not involved in mtb and he does not use it except on pavement
So far the product is good. I still need more time to use it and provide more accurate review.
