Front and rear smooth profile wire spoke wheels currently with 1" bearings, but can be swapped to 25mm if needed for a newer chassis. Front wheel is 19x2.5", rear is 17x4.5". Michelin tires with less than 600 miles, with drive sprocket and polished rotors. If the ad is up, they're available, so inquiries asking "if available" and or without a phone number will be ignored. I don't text and have limited time for emails, so they won't get answered without a contact number. So, a phone call is best for a prompt and accurate response. John at 53ZERO-477-71FIVE8
