to put costs of " bent tube" into perspective...I have the ventura system on my gen1 which has a luggage rack with tall hoopfixed onto side rails( which are bolted to the bike) , it can be swapped over with a grab rail. The side rails cost £97, the packrack about £60 odd, and the grab rail £20.So its expensive just to use as a grabrail, but cheap option if you use it for luggage carrying like I do.
Think of what you earn per hour at work, factor in R & D time to get the right fit for a piece of bent tube, then make more, then paint them, then post them...FFS anything under £50 is really a bargain in my book...
