These braze ons are going to be standard on your seatstay for disc brakes. Internal cable routing is nice, but forget hydraulic brakes.
I was thinking mechanical disc brakes for reliability and ease of maintenance... are hydraulic that much better? Seems unneccessarily complex to me. Do they make universal guides that can mount either hydraulic or mechanical, that way I can be flexible?
This bike will be equipped with a rohloff hub and yes, I'll be routing the cables on the bottom of the downtube...
Thanks,
