anyway, i'm thinking of upgrading the gears & brakes & chainset to deore xt eventually, but i need to know how the acera x stuff performs.
has anyone had any experience with the acera x groupset.
I'm a big fan of the lower-end Shimano stuff. Sure, it's heavier than M900, but Acera is virtually indestructible.
De-grease it, clean out the shifters and mechs with Brunox and it'll most likely work like new (unless the bike has fallen and the mech is bent).
Check the chain for stretch. If the chain hasn't been neglected completely, there should be none and it should be good for a few more tens of thousands of miles.
As for the frame : Yes, there's a Kona decal on there. However the decal doesn't necessarily make it a good bike. This one really isn't worth wasting a good XT groupset on.
Stick to the Acera parts and use it as a beater, pub bike, mud bike or general all-purpose tool. You'll have more bang for your buck than if you restore it and put the marginally better XT set on it.
