True â€œCompressionlessâ€ housing: High Purity Alumina is FIVE TO SIX TIMES STIFFER than aluminium alloys, and even 50 to 80 % stiffer than steel. OK, so theoretically it compresses a bit. But you won’t notice it. Honest. It is also FIVE TO SIX TIMES STRONGER in compression than both aluminium & steel.
Effortless Gear Changes:Less force required to actuate gears + brakes, creating a â€œlight-actionâ€ feel at the levers.
Less Maintenance: Due to the compressionless housing and protective Spinal Wrap, derailleurs are not only easier to fine tune during setup (theyâ€™ll work over a wider range of cable tension), but that they also don’t need to be re-adjusted as often as other systems.
Totally corrosion free!! High Purity Alumina is an extremely inert material. No coatings to peel off, no chipping and spalling paint. Zero corrosion for life!
Lightweight: The density of alumina is only 3.65 to 3.85 g/cm3. This results in outstanding stiffness-to-weight and strength-weight ratios. Total weight of vÃ©rtebrÃ¦ ceramic housing is only 46 to 52 g/m.
Enhanced Flexibility: The special segmented design is more flexible compared to traditional bowden cables; this design allows shorter cable routing using tighter-radius bends, resulting in less overall weight. Despite this, there is also reduced friction between the cable and liner, since the outer segments do not squash the inner cables like conventional housing.
Low Friction: Ceramic materials have an inherently lower frction than metals. Combined with our stainless steel cables and teflon liner, this results in considerably less friction and practically zero wear.
Extremely hard & durable: In fact, most engineering ceramics are so hard, they normally require different testing procedures to metals as it is not practical to make the same economical test specimens! In comparison with all metals, hardness is best described as â€œoff the chart!â€.
