- Large diameter rollers (34 to 44 mm) : These rollers
are reinforced for added impact resistance, and their
large diameter makes for smoother rotation.
- Rollers individually riveted into their tracks: this
delivers incomparable durability. The 3.6 mm spindle
is big enough to absorb impact and bear considerable
weight.
- Density: The RR-400 is exceptional in more ways than
one: it features 28 rollers per meter, with just 1 mm
between rollers.
These characteristics ensure remarkably regular descent,
thus enabling shallower gradients and saving space. |
