CMO, HLE
CMO(クロモリ)、HLE(マンガン)はプジョーが製造したパイプ素材で、製造プロセスと相まってフレームの寿命をより長期に保証すると説明されています。HLAについては、あるカタログに下記のような記載があります。
「HLE」はサイクルズ・プジョー社が開発した特殊な合金(Micro alloyed steel)で、マンガン・ニオブ・アルミニウム・カーボン・チタニウム等、通常航空機に用いられる素材から構成されています。 サイクルズ・プジョー社によれば、上記の素材を用いることで金属の機械的特性が大幅に改善され、通常のフレーム・チューブよりも軽量(フレーム重量を7オンス/199g削減)かつ頑丈なものになったということです。
PE300 VENTOUXについては、80年台後半から91年頃までHLEを、92年のモデルにはCMOが採用されています。
無論、ReynoldsとColumbusによるチューブも引き続きプジョーの上位モデルに採用されています。
Own Peugeot Frames (From the catalog of Peugeot)
Of course, the choice of material for the fabrication of the frames is essential. Peugeot is able to deliver the best quality here like no other. The enormous know-how in the production of cars speaks volumes here, of course. The CMO chromly and the HLE mangalloy are pipes produced by Peugeot itself. A quality that, together with the unique production process, guarantees a long life.
HLE TUBING (From the catalog of Peugeot)
HLE is Peugeot's exclusive alloy tubing. It is a “micro alloyed steel” which is composed of Manganese, Niobium, Aluminum, Carbon and Titantium, which offers a lighter, yet stronger frame. These elements are commonly used in the production of aeronautical steel. The introduction of these elements results in a steel with dramatically improved mechanical properties when compared with more conventional steel. The strength to weight ratio of HLE tubing is far superior to that of conventional tubing. Using this tubing enable Peugeot to save more than seven ounces in the weight of frame. The HLE tubing, when used with our patented internal brazing system, gives Peugeot a frame which is at the top of its class in performance and reliability.
Renowned tube manufacturers (From the catalog of Peugeot)
Highly specialized tube manufacturers include Reynolds and Columbus. These manufacturers do nothing else than manufacture tubes and have a very large production capacity. These renowned brands are also used for an important part in the Peugeot collection.
