I like the idea , but there is a lot of drag and there is a constant ratcheting , so it always ticks away and there is extra wear . Add the weight , massive Q factor and having to modify the frame to fit one I'll say no thanks .

Another thing that at first I think wow that's just what I need but after a little thought I'll just stick with the one ratio drivetrain :lol:

Have you had a look at the schlumph cranks ?

Have it, love it.

Q factor?? Flat pedals on rough terrain will change that, yes it makes a noise in the big ring position but drag ? Not sure.

Pluses : instant shifting, no lost chain. Great on rolling tracks it's like an instant 2 speed.

Minus : heavy and it cost heaps (got it when just released) now just buy a used one

I would include a photo but don't know how to off the I phone
