Bwaa haahaaha. There has to be SOME difference between these tubes and the stuff BF, Brompfication, etc., all sell for exhorbitant amounts, right? The one on ebay is actually almost perfect in length, I could live with it. Being twice as thick will make it heavier, obviously, but it would still be considerably lighter than my steel version at half thickness, right? No point in getting something that weighs more. With shipping it is around $45 which is eminently manageable - but again, I don't believe you ever get something for nothing so why is this so cheap compared to the ones the bike folks sell? Just markup or is there a difference structurally or in finish or something? Thanks, you are being super helpful =)
