Just got a used tandem (Trek T900) that has twist shifters. I don't know the model number off hand (of the shifters), but I think they maybe be SRAM MRX Plus, according to the Trek website.
The grips have two sections: The twist/shifter section, of course, is closer to the middle of the bars and is about 2 to 2.5 inches wide. On the ends of the bars is a smaller section (1 inch?) that does not twist. I haven't tried to remove this section, but was wondering if it can be removed so that bar ends can be installed.
I've never owned twist grip shifters before, so have no idea how it would work to get bar ends on there. I'm hoping I dont' need to change to thumb shifters, but would do that if need-be.
Thanks for any advice.
