This is the second time I am gluing my own tubulars and I am wondering if vertical trueness of the tubulars is important for a racer? I have just reglued my tires back to my zipps coz the glue seemed to have been washed off by lots of wet weather riding and it seems that I cant seem to get the tires on vertically true. Lateral trueness is excellent tho. There is a 1-3mm hump at a portion of the tire and is noticable if u spin the wheel in the stand. Is it a concern or is it impossible to get a tubular nicely true vertically? I have seen tubulars glued by more experienced wrenchers and they do not seem very vertically true all the time but mine looks a bit worst. THe vertical untrueness should not cause a wipeout or watever during my crit race in 24hrs time right?
