Bummer. Not quite a deal breaker, but for what carbon frames are going for, this needs to be standard IMO.
Meh, doesn't bother me much. Allows for different routing options (moto routing) and with the foam tubing it's silent. A little more involved on initial install, but not a big deal. In my experience tube in tube routing, although an easier install, is louder since fit isn't tight enough to prevent rattling but not wide enough to accommodate foam tubing.
My only gripe with the cable routing on this frame is the dropper routing. The way it routes under the lower shock mount and up into the seat tube is a pain in the ass to feed in or out when you need to remove the post. Much easier removing the shock first, which is a pain in the ass in itself...
Good to know on the dropper routing. I use the foam on my alloy bikes, and it does keep it pretty silent, but it’s a pain whenever I’m replacing shifter/dropper housing, especially when I have to go through a rear triangle. Brakes are usually one and done. Noise from guided routing shouldn’t have to be an issue. Maybe I’m just too demanding haha
