Tweaked as in misadjusted or tweaked as in bent?  I've got my old derailleur kicking around if you want to throw it on?  We could make a day trip out of it if you don't have time for an overnighter.

I'll take a closer look today.

I've got a stand and a good collection of tools, bring it over for a tuneup if you want.

If I'm able to burn some PTO, tune-up Friday morning and do a ride somewhere after?

Rain and snow Friday. I'll ride in about any weather, but I wouldn't burn PTO to ride in that.

Didn't realize chainreactioncycles.com was in the UK. My parts are currently at London Heathrow.

Do I need special tools to install the new chainring?

You shouldn't, but what cranks do you have?  I don't know how the SRAM or Raceface cinch chainrings work, but Shimano should just be four or five bolts to fix the chain ring to the crank arm.

You may have to pull the cranks out of the bottom bracket.  You'll pop the chain, then unbolt the right crank from the assembly (those are carefully torqued, ease them off evenly), then tap the shaft out of the bottom bracket with a soft mallet.  Good time to check the bearings in the BB for play or crunchiness, and if they're serviceable give them a greasing.  Most modern BBs are sealed, so there's no greasing to do -  when a bearing goes bad you replace the whole unit.  A little grease on the crank shaft helps it slide back in easier though. When you put it back together, torque those bolts on the right crank carefully and evenly like you would a head gasket, sneak up on your final torque setting. That torque setting should be on the crank arm itself.

Did I say I wanted a Deadwood? I may have been hasty. This hardtail will roll on 26x5 or 29x3 or everything in between, and only costs an arm and a leg.

22 pounds though!

Are you going to have bike frames laying around like you do 4wd vehicles?

You say "going to have" as if you're under the impression that it hasn't happened yet.

Luckily I haven't gotten into ebikes (yet), so there's no gruesome motor swaps in my way of building the ultimate frankenbike.
