This is a Tacx smart trainer. I bought it new for about 150,000 yen. I'm selling it because I no longer use it. --Additional Information------ (Personal impression) I think the sound is quiet. I think there is little vibration. It's quite heavy, so it might be difficult to carry. - Brand: Tacx - Type: Fixed roller - Accessories: Front wheel stand - Design: Stable triangular structure Thank you for looking.
