Khung trên cùng của khung chính này được làm từ thép mạ kẽm chống chịu thời tiết và chống gỉ.
Đặc điểm:
The galvanized steel on this tube feels way sturdier than the original that bent after two winters. Bolted right up to my existing frame with no drilling, and it's holding solid through all the jumping my kids do.
Ordered this to replace a bent top tube and it slid right into place with the existing frame hardware. Three-year limited warranty on a replacement part like this is reassuring, and it met the ASTM safety specs I was checking for.
The galvanized steel has held up through a whole rainy spring without a spot of rust. Bolted right onto the existing frame with no drilling, and the fit was spot on.
