Swapped out my bent top tube with this one and the fit was spot on. The galvanized coating has held up through a rainy month outside without a spot of rust.
The galvanized steel feels way sturdier than the original tube that rusted out after two winters, and the bolt holes lined up perfectly on the first try. Three-year warranty on a replacement part like this is a nice bonus too.
Swapped this top tube onto our frame after the old one rusted through, and the galvanized coating feels noticeably thicker than the original. Bolted up with no wobble, and it's nice knowing it meets ASTM standards.
