Stvn V. Posted May 1, 2007 Report Share Posted May 1, 2007 hellowdoes anybody have a pic of a unpainted trials frame ?(just the alu itself)shouldn't it weigh less ? Quote Link to comment Share on other sites More sharing options...
leigh_verner Posted May 1, 2007 Report Share Posted May 1, 2007 In theory yes it will weigh less but saying that it will only be a very small amount of grams, not worth taking the paint off at all.....And on some frames can even weaken the frame slightly around the welds when good paint is removed.....

Luano Posted May 1, 2007 Report Share Posted May 1, 2007 zoo's are not painted i dont think just lacqured i might be wrong thoug but they look good.and removing paint does not in any way weaken a frame its not poosible that paint strengthens he frame.

Simpson Posted May 1, 2007 Report Share Posted May 1, 2007 YEA it really is! thats why all modern frames are silver obiously!!! *sarcasm*But na not enough difference to either consider doing really Quote Link to comment Share on other sites More sharing options...
echo_897 Posted May 1, 2007 Report Share Posted May 1, 2007 surely if you strip all of the paint you will then have to lacker it all again to stop it going rusty.which will just put back on the few grams that you have just stripped off.

BenLeacock™ Posted May 1, 2007 Report Share Posted May 1, 2007 To be honest i dont think there is any point at all stripping the paint off. For 1 you make the bike look worst than it does with stickers and with a couple of grams off your not going to notice any big difference when riding. Just notice the looks of other people around thinking your bike looks a mess. I say stick with original and keep stickers and paint. Personal opinion though.

James Quigley Posted May 1, 2007 Report Share Posted May 1, 2007 Aluminum shouldn't rust.You WILL save about half a gram taking the paint offand it is possible to weaken the metal if you use a really 'aggressive' agent to strip the paint.

(I think)It doesn't, it oxodises into a non-pourous material, so only the top surface 'rusts'.Are bike paints lighter than house paints? Cus buckets of paint are quite heavy....

Luano Posted May 1, 2007 Report Share Posted May 1, 2007 if you use an aggressive paint stripping agent it will weaken the metal if u leave it on to long like overnight but to take of the layers of paint it wouldnt unless the frame is made from really cheap metal like a few brands i could name Quote Link to comment Share on other sites More sharing options...

sundance Posted May 1, 2007 Report Share Posted May 1, 2007 Well yes it should make the frame lighter but as everyone says by so little amount. So why do monty koxx etc spend so much money on buying brake levers and ti bolts and other silly little stuff that will also only save a few grams, its silly how much people pay to save a gram or 2, does kinda make you wonder why manufactures that are all about light bikes i.e monty and koxx do bother painting frames? maybe it is because if not painted then they will look kack and therefore will not sell many? Anyone else agree or disagree with that? Lets face it if you are rich enough to spend like twice price to save a few grams on any component your going to want it to look like you spent twice the price ehh Quote Link to comment Share on other sites More sharing options...
T_PRO Posted May 1, 2007 Report Share Posted May 1, 2007 I think my T-Lite is unpainted. I don't think it would make that much of a difference to the weight though. Quote Link to comment Share on other sites More sharing options...
Grant H Posted May 1, 2007 Report Share Posted May 1, 2007 removing paint won't make the frame weaker, its just what you use to get it off...use nitromorse and wipe off after an hour and it won't weaken the frame and it will take all the paint off.DON'T leave it on over night as nitromorse is pretty corrosive stuff.

2sixstreet Posted May 1, 2007 Report Share Posted May 1, 2007 Schwinn bikes went through a phase of only anodising their top end frames and labelling it 'zero weight paint'. So, if you dont want a painted frame but dont like polished/dull aluminium then anodising could be for you.Fun fact for today: Jumbo jets that have a polished aluminium finish do so primarily to reduce weight. Its a lot of surface area that if painted would be added weight which has a significant effect on fuel consumption on international flights.

Ali C Posted May 1, 2007 Report Share Posted May 1, 2007 paint can be up to and beyond 200g, thats like half a pound off the bike.anodising is lightest though, and tougher...I wouldnt worry about it being more brittle, think how many anodised parts there are on the bike.

2sixstreet Posted May 1, 2007 Report Share Posted May 1, 2007 anodising hardens the surface making it more brittle? more likely to crack?Anodising will surface harden the aluminium but this is a good thing. Its essentially an oxide layer produced from the parent metal which can be coloured. Typically used for components that require wear or corrosion resistance (or to look pretty) so not that important for a frame. Theres no negative effects on strength etc. Quote Link to comment Share on other sites More sharing options...
