How do I prevent STI shifter cables from blocking access to my Randoneering Bag or Handlebar bag? I've got drop bars with Shimano Tiagra STI shifters and want to use a Rando Bag on my small front rack or a handlebar mount bag.  Currently the shift cables jut out between the drop bars and hit in to the sides of my bag and can't be bent around it.  I have to run the cables under the top flap of my rando bag to get them out of the way, but this makes it hard to access the contents of the bag on the road. 

What can I do to prevent this cable from interfering with my rando bag that doesn't involve switching out my shifters?
The best solution is probably to move to either a different shifter setup like newer shimano 105/ultegra or SRAM (with cable routing under the handlebars) or to a barend setup like most randos employ. I know this isn't your preferred solution, but it's probably the easiest and most effective. If you mess with the routing/length on your shift cables, you're going to start experiencing shift slipping and improper shifting.
