So I'm trying to find out if anyone has tried out the K-Edge device on any Specialized frames yet...I'm considering it for the Roubaix Pro I recently purchased. It certainly looks like it'll fit OK and work fine, but it's new to me at this point. I've used N-Gear Jump Stop devices in the past (and really like them), but those require a mostly "circular" seat tube in order to set up and many newer frames have more unique shapes, especially near the BB area. So I'm canvassing here to hear of any experiences first hand with the K-Edge. I know that some Cervelos and Ridleys even require some additional hardware to permit the device to be mounted a bit forward of the seat tube...additional spacers and a longer bolt for the FD. Anyone have any experience or info about a Spec frame with this device? Thx for any input.
