Grr I'm having bad luck with my upgrades so far

Blew a tube trying to get my durano's on - and no stores near me have a 20x1 presta tube

Also, the rear derailleur needs some serious adjusting, I was tinkering with it for 2 hours and the chain is still skipping sporadically

And finally, my tekro brakes from bikeisland aren't long enough! at least i can swap the levers, haha...i still really want to replace these damn brakes...
