I bought a Stumpjumper about 4 months ago. A month or so ago I noticed nasty cable rub on my headtube that had went completely through the paint. This week, I noticed rub from the brake cable that has gone through the paint on the triangle, and actually started wearing through the aluminum.

I have taken care of the cable rub, but the damage is still there. I was looking at a friends new FSR yesterday, and the inside of his triangle has clear vinyl protecting it. Should this have been on my bike when I purchased it?

It's my fault for not noticing all of the cable rub sooner, but it's not something I was familiar with.

Cable rub is something that's going to happen on most bikes. About all you can do is put clear protective plastic over the places where the cables rub.

It's unobtrusive and protects the paintwork.

The places you need some frame protection are usually on the head tube, the inside of the rear triangle where the brake hose touches and with a Stumpjumper FSR or Epic underneath the bottom bracket where the front derailleur cable runs. The front derailleur cable can pull tight against the frame when the suspension compresses which wears a groove in the frame if you're not careful.

The damage is done...and that does suck. For future just use electrical tape, either black or the colored stuff to match your frame color. I use 2 small pieces for double protection.

You can expect a crack if you do have metal already showing signs. I feel bad and its not even my bike.

Glad I saw this thread. I just checked my Stumpjumper, and the paint on the frame has been worn away down to the metal in two places, by the Brain hose, and underneath the bottom bracket by the derailleur cable. I put on some duct tape. Hopefully no cracks to come!

Duct tape is not the best choice...use electrical tape. It's made for abrasion resistance.

Yeah, it's all I have right now. Thanks for the tip, I plan to pick up some electrical tape from the hardware store.

Electrical tape is abrasion resistant? Yeah ok and I'm a chinese jet pilot.

You need 3M. Ask your LBS if you can have some of the small pieces that come with all new spesh bikes out of the box but rarely get put on and end up being thrown out with the manuals. Or buy some and cut pieces to protect the problem areas as needed.

You must be a good pilot then....elect. tape is resistant to cables. Didn't think I needed to go any further. Of course it won't stand up to a coarse substance...damn dude.
