With so many bikes on the market and so many different configurations - we want to ensure you're getting just the right set up. We can customize the TrailTail front swing arm to suite just about any bike. We want to ensure you're going to get the right fit - the first time. So we ask that anyone ordering a chassis to please complete the FIT UP SHEET. And email it back to us with 3 pictures. One of the left side rear, one of the right side rear and one straight on the rear tire of your bike. Once we have the FIT UP SHEET and 3 pictures - we will proceed with your order.
