Thank you for viewing. This is a fixed roller from Wahoo. It's perfect for indoor training in the coming season. When used with Zwift, the resistance increases significantly on climbs, making for excellent training. In my opinion, the most significant scratch is in the last image. - Brand: Wahoo - Model Name: KICKR Core - Type: Fixed Roller - Color: Black - Shimano Freehub Please understand that this is a used item before purchasing.
