Title: subframe protection - chain rub
Post by: barryadam on June 07, 2005, 11:14:21 AM

Anybody have any proven solutions to protecting the aluminum subframe arm from chain rub?
On this forum somewhere, I've heard of a piece of metal added in the rub area, but have not seen any in pics or real life.
Hardened material (steel or Ti) or sacraficial piece (alum or PTFE)?  What method of attachment has worked the best?
Got any pics?

I am going to do the same and was thingking of using star board which is a very hard plastic might find it at home depot. I was just going to cut it to fit the sub frame and just tie strap it to the frame or saftey wire it.

I used aluminum as well. I used "Shoe Goo" to stick it on.
I thought that one the alum. whore out, I'd just replace it with
another pice. It's been on there for a good 15 rides.
Now if I can just get it off???

I used die protector (tough plastic) on another KX I had.
It worked good, but kept ripping off the zipties, and wire....

Thanks.

I'll try either a piece of aluminum angle or Ti sheet.

I also have some old polyproplene cutting boards that I could notch on the tabelsaw...

I'll try to post a picture when completed for future reference.

I just use a piece of rubber (pre-heater) hose sliced open, then wrapped around the sub-frame member, and held in place with zip-ties.  Its cheap, durable, and nice and soft.

I'm gonna have to try that rubber hose solution. Looks inexpensive and easy, just the way I like it :lol:

I used a piece of heavy guage sheetmetal which I had bent in an "L" shape and then riveted it to my subframe where the chain rubbed. It has worked great with very little wear as the heavy sheet metal is a much harder material than the subframe.
