Re:
Never underestimate the power of Stupid :facepalm: I was going over a bike I bought a couple of weeks ago, the seller said he'd been "fixing bikes up" for years and "knew all about bikes", even said he built bikes for friends... God help them! .. The evidence I found suggests otherwise :roll:
I picked up on a few issues when I bought the bike, reasoning they'd be easy to fix...
Bar tape, bars apparently wrapped by a blind man, not enough coverage on the tops, not finished off properly, lifted the hoods to find a spaghetti junction of bar tape...

Steerer top cap, noticed it didn't have one, it's not actually "needed" once everything is fitted I guess, but common practice to fit one (as you would bar end plugs). Which brings me to....
... Steerer bung, no top cap because there was no steerer bung fitted, carbon steerer. No internal bung or expanding wedge, stem bolts most silly over torqued, asking for something to break... :shock: which leads to...
No bung = no way to pull in the slack on the headset, not helped by the fact there was no crown race fitted to the forks, just the sealed bearing sitting about 5mm above the actual fork crown :facepalm: it wasn't even an integrated headset, or frame!
Moving on....
Bottom bracket felt rough, went to change it only to find the square taper cartridge BB had the drive side screwed into the non-drive side of the frame, and so the non-drive side BB sleeve was fitted to the drive side on the bike. I'm not even sure how this is possible, but suffice it to say he BB did NOT want to come out...
Never mind, seller mentioned the gears needed some attention, he was right, the front mech hit the teeth on the big chainring, and the rear mech hanger was loose owing to the bolts securing it being loose :facepalm:
I shudder to think what the other bikes he's touched are like.
As I'd basically striped this bike down I reasoned it was easier to leave it that way rather than try and put right all the Wrongs I'd found
I'm no pro bike mechanic, but F-me! Some people's "bodgineering" is really something to behold :shock:
