Cable Cutting Thru Frame(5 posts)

I just bought a Douglas Fusion road bike from Colorado Cyclist. The bike rides great, but I did notice one minor thing while cleaning the bike. The front derailuer cable looks like it is cutting thru the bottom bracket just between the chainstays. It looks like the thick welds are getting in the way. Has anyone experienced this? I was going to run the cable thru a short section of cable housing at this juncture. Realistically the cable would take forever to cut thru the bb. I am just being anal or is this common on road bikes.

No, it is not common. Is there a cable guide on the bottom of the bottom bracket? Using some housing might work but I'd be worried about the housing slipping. Have you called Colorodo Cyclist?

Some of the older italian steel frames were actually designed to accept cable housing. You would cut a small section and that would be the guide. I did that on my bike and it worked well. Many newer frames actually have a plastic cable guide that screws into the BB shell. You can tell if yours was designed to accet housing because it is wider than a std cable guide. I made the housing long enough to clear the frame. There should be tabs to prevent the housing from slipping as well.

since its new I'd go back through CC and work the issue. If you decide to resolve it alone here's some options:
1. I assume you already have a BB cable guide? Some guides have a extended piece to route the front der. cable. Find a shop and check out a couple of different guides (they are cheap) and see if a different one might work better.
2. You might be able to get away with a small shim underneath your existing BB cable guide to extend the clearance
3. A small piece of housing as you suggest. This will probably impact shifting though

I would not let the cable eat the frame - regardless how long it might take. I used a piece of Gore brake cable liner to guide the cable around the BB housing. It seems to work. Also suitable: The special cable guide mounted on Cannondales (the Cannondale guys seem to be more careful than the dumbheads at Trek)
