Trigger shifters Deore and up are surprisingly adequate, deraillers and such are all solid considering the concept remains the same, cassettes and chains are almost the same. The only thing I'd be weary about are the forks. All of the old Rock Shox judy and Indy forks I've come across work pretty well, Rst and Sr Suntour forks dont seem to work as well in the first place, and the suck outright a few years down the line.
