Suntour “Power Ratchet” Thumb Shifters

Suntour Power Ratchet Thumb shifters modified. The right side shifter was modified by filing a metal stop down to allow for a much wider swing during shifting, tugging way more cable to clear 2x10 setup friction shifting.
Game changer for this build.
Thank you Eric Marth.

Just set these up on a 9 spd. Can’t seem to hold the shifts and have to keep my thumb on the shifter. Any tips? Loctite?

I was having similar issues before I switched over to the Suntour. If you have it setup friction, try to release all the tension and depending if your rear mech has a clutch it should come down the limiter/ LH on the mech. If the mech is just tugging everything to the smallest gear to the point you have to hold the shifter. That is such a bummer on rides, it is a huge drag. Try giving the cable a generous tug with your hand to stretch it out if it is new cables. If you have already done most of what I have said already? The screw that holds the shifter to the mounting pod could be replaced or run existing and loctite added if you wanted to. I would just be more focused on the shifting and making sure the rear mech when shifted into gear is allowing clean chain travel, hopefully there is enough chain to allow desired gear ratio and chainline is running smooth and travels through rear mech in all 9 speeds clean. Doing all of this in a bike stand is ideal but not limited to. Once the chainline runs smooth the shifts and any ghost shifting is sorta a part of friction shifting in general, much like a manual car, weird shifts happen during a ride, but having to hold a finger on your shifting cable to achieve engagement or all the gears dumping to the smallest gear can be solved with a rapid rise derailleur (rear mech) the shifts fall up, more prone to spin out but the best for off road trail riding.
