if your lucky, you might find a tensile adapter thingy you can just see it on here that screws onto threaded cranks and lets you run a bigger chain ring looks like you can still buy them. WIN or one of these?
doubt it, custom geos are available already but alot of people will not know what geometry they would require, companies spend alot of money finding an "ideal" geometry for a style of riding. there more than enough for your average joe and when you have bikes with alot of CNCed components changing the geo will need each part of cnced frame to be re-designed. i think. it'd be nicer to see more riders, more demand and as a result more companies with moar competition meaning cheaper gear
more than just length afects stability plus you'll be used to the czar so you'll be familiar with how it rides. try the gu for longer, if not you interested in selling?
there are a handful of disc 26" frames but putting 24" wheels will probably make the ride suck, you could look at getting a marino and copying a tgs geometry, only shorten the chain stays a bit.
no more warm beer amnesty i'm afraid meh, they sell tuborg now tuborg > carling to be honest food, beer and other stuff is well expensive on the inside, remember your suncream and buy a big water-carrying joby, or if your posh take a camelbak
