Title: Proflex 552 - PTFE-Rings from pivot - where to buy?
Post by: Lamima on August 15, 2011, 08:30:03 am

Hi,

i got an old 552 with totaly worn PTFE-Rings at the main pivot.
They look like this:

Does someone know where i can buy some new ones?
Does someone know the sizes of those rings? I can only measure the thickness of 3mm.

Hmmm, never heard of a kit specifically for the 552, I think a possibility is the RK003:
RK003   Attack Style Frame pivot                                       (fits '95 555,455 - '96 656 - '97 Reptile, Attack_

(http://d3d71ba2asa5oz.cloudfront.net/43000093/images/346167c.jpg)

The pivot part of the Frame of the 552 looks very similar to the bikes in the above list, so could be a good option.

Now you just need to find a RK003 kit.........................

Oh Look!

Here's one:

Good Luck!

I tried to buy from them a shock rebuild kit once and shipping to Europe is outrageous: 55USD for a small packet.

Wow,that's quite a lot (and too much for me).
And in addition, it does not seem that the rings in the package are the same as mine.

If you can get someone to pull out a set of the original bushings in newer conditons and take measurements, you might find a replacement here.   http://www.grainger.com/Grainger/wwg/start.shtml?cm_guid=1-_-100000000000001053399-_-4624274663&cm_mmc=PPC:%20Google-_-TPN%20-%20Brand-_-Grainger-_-grainger
