My 2nd new MRX 7sp grip shift has self destructed in less than a year, losing its click stops and
becoming a frictionless friction shifter that you have to hold on the gear.

Very annoying - I was happy to let one slip by as maybe a fluke. It seems to be a pattern. They
don't honor the guarantee either. (MRX: if you want to honor your guarantee send me mail and I'll
let everybody know, if you do.)

What can I replace it with directly?

24,000 miles? Maybe you just plain exceeded the expected working life of a low-end component like
the MRX shifters. How many cassettes, pairs of tires, and chains have you gone through in this time?
If I were riding the same bike 27 miles a day, 5 days a week, for three years (that makes 24k
mioles), buying an occasional shifter set wouldn't bother me - especially if the set were as cheap
as the MRXs are.

The first one was fine. I was complaining about what I replaced it with: two quick failures. If they
went back to the 1998 model I would be happy.
