Teb: Cov khoom thov rau lub tsheb log log yog feem ntau muaj cov khoom siv xws li txhuas alloy, hlau, thiab carbon fiber. Aluminium alloy log tau siv dav vim lawv lub teeb ci thiab lub siab-zog yam ntxwv. Cov log hlau steel tseem muaj qee yam kev ua lag luam hauv qee cov qauv kev lag luam vim lawv tus nqi qis.
Cov khoom siv carbon fiber ntau, raws li maj mam ua thov rau hauv cov qauv thiab khoom kim heev hauv tsheb thiab lub zog hnyav dua. Carbon fiber ntau lub log tsis tsuas yog txhim kho cov roj kev lag luam ntawm cov tsheb, tab sis kuj txhim kho lawv qhov kev ua tau zoo tag nrho.
Ib qho ntxiv, nrog kev nce qib ntawm kev tsim khoom siv thev naus laus zis, ntau dua thiab ntau cov ntaub ntawv tshiab tau thov, xws li cov khoom siv magnesium. Daim ntawv thov ntawm cov ntaub ntawv tshiab no tsis tsuas yog txhim kho kev ua tau zoo ntawm lub log HUB, tab sis kuj txhawb kev txhim kho kev lag luam tshiab ntawm lub log hub ua lag luam.
