![]() ![]() The cable end was easily seen at one end and there was one screw to remove a small cover at the other end. I never figured out how it went back together (because I didn’t bother to be careful or to take pictures). There was a spring, and a plastic ratchet-thing inside. Even though the SRAM was broken and going in the bin, I took it apart anyway. The replacement parts I bought were some non-brand-name ones of two different styles: micro-shift and handy shift. The original bike came with SRAM 7-speed shifter for the rear and 3-speed for the front. There are who-knows-how-many styles of grip shifters out there and I don’t claim any expertise in this area, but if you’re careful and take pictures, you might just be able to do it. Now the tricky part: replacing the cables through the shifters. I believe this is to allow the shifter to turn against the grip without sticking against the grip. One important note: I found a thin plastic ring in between the grip shift and the handle grip on each side. The grip shifter should slide right off once the setscrew is backed out a bit. To remove the grip shifters, find the setscrew(s) that hold them on to the handlebars. My trick for this is to slide in a flat screwdriver a ways, then pour in a dribble of soapy water. To remove the grip shifters, the bar-ends were removed, then using a bit of soapy water, the grips were removed. I like to work on one side at a time so that I don’t mix-up cable housings. The first step was to detach the cables from the front and rear derailleur and remove the grip shifts from the handlebars. The best advice from my repair class instructor was to go slow, take pictures, and be careful of flying parts and springs. This is a job I’ve never done before, but was willing to tackle because I’m mechanically inclined and careful. The reason for this is that the shifter body was cracked and the detents (or click-stops) wouldn’t hold the shifter in place at each gear. This made it so that I had to constantly keep my hand on the grip shift while riding. The bike would autoshift about four gears (of 7) whenever I started from a stop in 1st gear. Among other things, I wanted to replace the broken grip shifters that didn’t work anymore. ![]() I recently decided to fix up an old mountain bike to sell in the spring. For that reason, it’s worthwhile learning how to replace/install a grip shifter. Grip shifters were prolific on mountain bikes during the late 90’s, were replaced with thumb-index shifters, and recently made a comeback due to the fatbike craze. ![]()
