I've had my Ventana El Rey for a few years now. Have been using the RP23 lever more frequently to open 'er up on descents, and firm 'er back up for the climbs. Got a little tired of reaching down all the time, so got together with my 12 year old (mechanically inclined) son to figure out a solution. I had seen a solution on MTBR before that used the angled Schrader valve as a support for a cable/spring setup. Problem is my RP23 has a Schrader valve that's 90 degrees/perpendicular to the lever. So.....
I had a friction thumbshifter from Nashbar I picked up for $0.99 a while ago. We rifled through my bin of old cyclometer parts, frame pump holsters, barrel adjusters and miscellaneous plastic. We located 2 springs (one extension, one compression), and (from Home Depot), picked up an aluminum 1/16" cable ferrule/stop set (enables you to create an "eye loop" at the end of the cable). Removed the lever, drilled a hole at the bottom and inserted a 3/4" bolt. Joined a Cateye cyclometer mounting bracket and a Zefal frame pump bracket and wrapped it snug around the shock body using the "worm screws" they came with. installed a barrel adjuster in the Cateye mounting hole. Installed a different Cateye cyclometer clamp on the shock's spacer to anchor the extension spring. Attached the cable and springs to the lever bolt. Hopefully the pics show how it all came together.
When you pull the cable, lever moves to "open" position. When you release it, the extension spring and compression spring work in concert to return the lever to "platform". My son was a big source of ideas for this...nothing like a 12 year old to think outside the box! Hope this helps others with ideas for a solution (I've seen a few posts looking for something like this).
