Thank you for viewing. The Japanese-made GROWTAC GT-ROLLER FLEX3 is a fixed roller that provides safe training with a front that allows for dancing. - Brand: GROWTAC - Model Name: GT-ROLLER FLEX3 - Country of Manufacture: Japan - Type: Fixed Roller I purchased this, but the total number of times used was less than 20, and it has been stored indoors as dead stock, so I am putting it up for sale. As mentioned above, the frequency of use is low, so it is relatively beautiful, but please understand that it is a used item. It is not compatible with thru-axles. I will include the front quick release, so please use it if you like.
