Thanks Bruce. I expected as much...
Currently looking at Ergon GP grips as opposed to swapping-out the actual handlebars for bull horns etc. - getting people's thoughts in a separate thread - feel free to muck-in ;-)

I'm thinking by going this route I limit potential folding issues and hopefully minimise flex. Having lived with whichever GP grips I go with I will then come back to whether I still need to increase reach.
