I've been toying with upgrading to push button shifting due to pain in my thumb joint (probably arthritis) with my ancient conventional setup (2x10) Can't justify north of £500 for SRAM and saw a 30% off deal for August orders on wheeltop EDS medium cage mech and shifters which brings them in at £280 Is there anything to be concerned about, it'll be going on an equally ancient On One carbon frame and used for pottering about on easy trails, no rock gardens or muddy stick strewn ruts. I'm in Spain so moisture ingress isn't an issue either. Any real world experiences out there? Thanks

I've done a bit of research and the only thing I saw of 'concern' was possible corrosion which won't concern you in sunny Spain.
