The OM-1<\/b> is Rivendell\u2019s original derailleur, something Grant has wanted to make for many years.
\nOf course, you can use it on bikes other than Rivendells too.<\/p>\n

One of its biggest quirks is that it moves in the opposite direction from a conventional derailleur.<\/b><\/p>\n

\"\"<\/p>\n

We really want people all over Japan \u2014 including those who live far away from our shops \u2014 to be able to try this derailleur, so I thought I\u2019d go through some of the questions we get most often in-store.<\/p>\n

The first two are always:<\/p>\n

\u201cHow many speeds does it work with?\u201d <\/b>and \u201cWhat shifters can I use with it?\u201d<\/b><\/p>\n

Let\u2019s start with the shifter.

\nThe OM-1 is compatible only with friction shifters \u2014 the kind that move smoothly without fixed clicks.<\/b><\/p>\n

It is NOT compatible with indexed shifters \u2014 the kind that click into each gear position.

\n<\/b><\/p>\n

Hmm. That\u2019s surprisingly difficult to explain with words alone, so let\u2019s go through some actual examples.<\/p>\n
