I'm just curious, is your frame fully integrated or is it semi-integrated and you just want to clean up the cables before they exit out from the stem?
I'd just opt for an integrated stem+bar that already have built in cable routing. That would probably cost a lot less than some of these boutique stem options. It seems these stems with hidden cabling weigh as much, if not more than a standard stem.
I personally like exposed cables, it looks more industrial!
The frame is fully integrated, but I want access to the hoses for the hydraulic brakes so I can pack the bike down for travel in a Orucase Ninja bike bag (you need to be able to take the fork off). I'm planning to uses hydraulic quick disconnects similar to the ones Sakizashi posted and while I can make an FSA SMR stem work, imo, it's not the most elegant solution.
Pros of the Zeno System vs. Formula:
- Assembled they are nearly 10mm shorter 2mm smaller in diameter.
- They can be placed anywhere on the line.
- They do not require special cables.
- You can reinstall them a couple of times in the case you kink a hose or something goes wrong with the install.
Cons:
- The downside is that the male end of the hose is larger and requires a 10mm hole to pass them through.
That "con" is not an issue with the FSA SMR stem and I designed my own headset top caps so I could pull them through to drop the fork.
Oh dang, you might have just swayed me over to using those. And looking more closely, I really like the volume adjuster they've got!
