I want to mount the following SunRace clamp-on shifter set horizontally as a "thumb" shifter on a straight MTB handlebar (22.2mm). I will remove the left lever and only use the right with the clamp.

The problem is that the lever is not easy to reach because it swings from parallel with the handlebar to straight forward. I would like to have the angle of the full swing of the lever go from a little towards me to a little forward.

Is there an easy way to change the angle of these stem-mount shift levers (which are almost the same as downtube shift levers) by about 45 deg?

Note (in second pic) that these are meant for stem mount, so there is a cable housing stop for the part of the shift cable housing that goes from the handlebar to a downtube stop.

  • So, do you have a cable/housing stop that will work with these?

  • Also, do you already own these shifters, or are you planning on buying them to modify them?

    I'm not sure I understand the question - are you looking for something like Paul Thumbies (paulcomp.com/thumbies.html)? You might be able to do a little modification to mount them on the handlebar with those.

    For <$20, you probably have to go with friction shifters (sunrace makes 5 dollar friction shifter sets, for example) or jury rig your own mounts using something like hose clamps and maybe a bit of pvc. What are the front derailleur and rear derailleur?

Note that there are different levers, depends of the final position. For downtube, head tube or steam, see the ilustration in the bottom of the page:

Some of them have the cable stop vertically, equal as the tube hanger, and other at 90 degrees of it.

Although I haven't done it with this specific shifter, some similar designs with a fixed cable stop can indeed be adjusted this way. See for example this instructional video for Gevenalle shifters.
