Thank you for letting me join your group. My Giant Sedona 21-speed has a SRAM MRX Plus grip shift for the rear derailleur. It suddenly wants to stay in the 7th gear position. I can shift gears down to the first gear position, but the shifter does not click through each gear, it just goes smoothly through the gears against what feels like spring pressure or tension that wants it to return to the 7th gear. If you want it to stay in one of the lower gears, you have to hold the shifter in that position, as there are no longer any detents or stops to keep it in gear.
I am a complete newbie and don't know what the inside of the shifter looks like, but it feels as if it were constructed with a ring of 7 ratchet-like teeth and that ring is no longer there. Hope that makes sense.
I watched the "How to Adjust your Rear Derailluer" video, but I didn't think that was my best first step, because I cannot put the bike in the low gear (or anything but high) unless someone is holding the shifter.
Any help or advice is appreciated before I take it to the local bike repair shop. Thanks.
