ONE-FORTY 500

PROLITE 6066高品質鋁合金材料，具備輕量與耐用的特性。透過油壓成型技術，可以讓同一個車管擁有三種不同的管壁厚度變化，以達到理想的剛性重量比。

將鋁合金原料置入模具之中，將加熱後的液體由管材內部向外高壓推擠，使鋁合金能均勻地貼合模具的形體，這方法可打造出更具複雜的管形變化。

犀利的過彎與快速碾壓林道，這需要精準的操控性能支援。異徑頭管，使用1又1/8”管徑往下擴大漸變至1又1/2”的尺寸，搭配錐形豎管的避震前叉，能大幅提升操控所需的剛性要求。

在金屬管接管之間的焊接位置，再多一道工序，使外觀上更柔順，就如同一體成形的感覺。

在管線進、出車架的端口，都設計有合宜的止線栓，整車外觀簡潔，管線也能延緩環境所造成的性能影響。

部分敏感零組件的螺絲，採用內六角星形規格，且僅能從單側鎖固，避免施力不當造成螺絲損壞。

A suspension design where the traditional pivot point on the seat stay is eliminated in favour of a flexstay design. This uses the compliance of the material and specific shaping of the tubes to allow for the seat and chain stays to move apart as the suspension moves through the travel. By removing this pivot point at the seat and chain stay junction, we save weight, reduce maintenance needs and add stiffness to the frame structure.

美利達在車架頭管上方開創特別的管線進入口設計，使煞車與變速管線順暢地由頭管進入車架內部，車輛外觀更為簡潔俐落，相關零組件仍為主流規格。依據不同車款型號，部分包含龍頭、把手皆為全隱藏走線；有的車款則為半隱藏走線設計，管線順著龍頭的下方，進入頭管內。

Suspension system that uses a Flexstay design to reduce weight and maintenance, is Adjustable to run 29” or 27.5” wheels without altering the geometry and has Size Tuned shock progression that increases with frame size, so lighter and smaller riders can access all of the travel and heavier riders get the support they need on big hits.

An optional extra coverage mudguard that bolts rigidly to the back end of our bikes, protecting the rider from dirt and water spray while reducing noise, movement and prevent damage to the paintwork.
