Sealing a Venge

So being a mechanic and a new owner of a Venge, my little OCDness has reared it's ugly head and it has me questioning what I can do to help seal off the cables inside the bike from any and all contamination and water. I have debated putting a little silicone around the cable stops.

Anyone have any ideas/ thoughts on if this is good, bad or ugly? Or better ideas? I have thought about putting small pieces of inner tube underneath the stops aswell in order to create a "seal"

I understand the OCD thing, but I don't think that I would worry much about this. Unless you ride in the rain or muck a lot, not much contamination will enter, plus any seal you come up with won't be effective for long.

It looks like the brake cable housing is continuous inside so no sealing is needed for the cable, but you could use silicone caulk to prevent water entry to the frame.

The gear wires are a different story. Use silicone grease (often sold as O-ring grease) between the ferrules and housing. Then make a donut out of a thin piece of rubber (an old tube, or a fairly thick balloon) and thread it on between the ferrule and frame to seal that point of entry. Make sure the hole is big enough for the wire to run freely.

Now for the bad news. No matter how diligent you are, water might still enter (usually around the seatpost), and accumulate in the BB shell. On a metal frame I'd suggest drilling a weep hole if you don't have one. But you probably don't want to drill a carbon frame (though it's probably OK if done right), so once in awhile remove the post and put the bike in a warm place to evaporate any water that might have entered.
