FW-05 PLUS also includes front universal shafts, threaded aluminum oil shocks, turnbuckle linkage rods to make adjustment quick and easy, and V-One RRR rear hubs for more adjustability and better performance.

又一城- 05 Plus还包括前世界槽，螺纹铝石油冲击， turnbuckle联系棒作出调整，轻松快捷，和V -一rrr后方枢纽，为更多的适应性和更好的表现。

Plyfil composite yarns is similar to two-ply yarn structures.

纺纱方法决定着成纱结构，成纱结构与纱线组成原料又决定了纱线的性能。sirofil复合纱线纺纱时长丝与短纤纱须条的间距及长丝的张力，plyfil复合线加工时二组分间并线张力对成纱结构及纱线的性能有着重要影响。sirofil复合纱的成纱横截面呈近似圆形结构，长丝位于成纱的一侧；纵向呈有"股线螺纹"的单纱外观。plyfil复合线具有类似于传统双股线的横截面和纵向外观。
