The tread on a tubular is not always exactly straight relative to the chafing tape that goes over the sewn section, so if you align the chafing tape, you might see some tread wiggle and vice versa. As others have noted, you should mount the tire, pump it up slightly, and then complete the alignment process before pumping to full pressure.shaochieh said:I put enough glue three thin layers both on my wheels and tires. The small wobble worried me a bit I almost gave up on Tubular.
20+ years with tubulars and in my view, good enough is what you can accept. Nothing will run as perfectly straight and round as a good clincher, so give your tubulars a break and let them wiggle just a bit if that's what they want to do. Not going to hurt the riding.shaochieh said:What is good enough?
