DISRAELI GEARS

Sensah RX

Sensah RX main image

I believe that the Sensah RX was Sensah's very initial derailleur design. If so, it is an impressive first effort:

  • It is not aimed squarely at the very low end of the market. It has its steel parts, but it also shows ambition.
  • It has a novel cable routing.
  • It also has a novel chunky cyborg look.
  • The branding is tasteful and restrained.

When I first saw it, I liked it and immediately made a note to keep an eye out for future Sensah models.

Sensah models.


This example is a long cage RX, suitable for any number of fine Chinese mountain bikes.
