I was thinking about spraying my brake mounts, but then I found something to do so that idea never left the ground really, just buy new bit's that are better colours.
Sound's like some one needs to grease some things up, take your pedal's off, cranks and bottom bracket out, have a look to see if they are still good to use then just grease them up and put them back in. Should be alright after this.
Could be made to hold the bike over the side, try modifying a side car or something into a bike rack, I know I have seen a motor bike with a surfboard rack before !
Sorry to say but I didn't even watch it through, I thought it was that bad, I agree with the other's on how you actually managed to snap the frame, how !?
Anyway, all I can say is get out there and keep at it, progression is the key.
It should produce more power with the larger rotor, I personally haven't used the avid disc brake's so can't comment on those but I think they will have more pimp factor and will work great, get one !
Not sure yet, they are quite new on the market, if you have a look around on the web, if you don't find one you could always get one throuhg myself if you must have it.
Well, i'm not that fussed about the weight on my rear wheel anyway, if you have a heavier tyre/tube then you will have more certrifugal force which could mean me gapping further. (Y)
