Hi cce, that's a great looking Lava Dome. My wife and I got one each in 1994 and I've just got back into riding mine after devoting time to windsurfing (she's kept on riding and progressed to a Santa Cruz Juliana hardtail in the meantime).
I've got Avid Arch Rivals on mine, fantastic engineering! I've also put XTR brake controls and XTR rapid fire shifters on there. Rest of it is original, including forks, have been tempted to think of suspension forks but can't quite go there. My wife's bike actually has Manitou 2 forks and I've researched rejuvenating these but it doesn't seem possible due to parts not being available.
Did a 16 mile xc/road mix this morning and loved it.
I'm looking at bringing my wifes bike back to original spec since we have all the original parts including bottle cages with tyre levers and patch kit.
