Bike Shifter Extension

Bike Shifter Extension

On my mountain bike, I was frustrated with the position of my Shimano shifter - I awkwardly had to reach to change gears. It was not long enough, so I designed an extender so that it was better positioned, see the photo. I have designed two, one for the Shimano Altus shifter and another for the Shimano Acera shifter. For each variety, I have included a straight version and one with a right 15-degree twist and one with a left 15-degree twist. Shimano Acera - 14.5 mm gap Shimano Altus - 10.3 mm gap Print flat on the build plate (designed without supports). You will probably need to file the elephant foot. You can experiment with resizing to get it to fit other shifters. Please comment accordingly. Tools: file shoe goop painter's tape Installation: - check for fit with your shifter - file the shifter to fit - determine the best position for the extension - coat the shifter in Shoe Goop - fill the gap of the shifter with Shoe Goop (even if the fit is loose) - press on and wipe away any excess Shoe Goop - wrap with painter's tape to hold it in place - let it set up for at least two days at room temperature (don't be tempted to touch it) - remove the tape after one day (don't be tempted to touch it) - add more shoe goop as needed - shoe goop tends to shrink - let set up for another two days - take it for a test ride; if it doesn't work, you can always remove it with controlled force (that is why you use Shoe Goop rather than something like Epoxy or SuperGlue _________________________________________________ The resin print is available for purchase at the following website: Structural Expressions https://structuralexpressions.weebly.com
