Proflex 753 parts?

I have an early 90's Proflex 753 Generation 4 with the yellow elastomer rear suspension and a Rock Shox hydra front.
My yellow elastomer in the rear is hard as a rock and has shrunk also judging by the 1/2 inch play in it.

I am looking for anything out there either elastomer or springs that I can retrofit to fix my suspension.
I have an inquiry with Rapid Descent out of scotland that sells parts for the later models but nothing for my vintage that I can tell from there website.
If I can't find anything I may just put in a big washer to lock it out and make it a hard tail.

Any suggestions?

I remember someone once suggesting that a trip to your local skateboard shop would be in order - skateboard trucks use elastomer "donuts" and you might be able to cobble something together that way. Also, you might try the K-2 forum on MTBR.com; used to be some Flex-heads that read that and they might have a better lead. I used to have a 756 and had switched the elastomers F & R to Noleen NR-1 shocks. The Girvin fork was still in my opinion a work of art and function; that bike turned like Amtrak (too bad that that travel was so limited). Ah well, good luck on your quest!

Shock

"I used to have a 756 and had switched the elastomers F & R to Noleen NR-1 shocks."

Same here, it works better then the original shock.

You might email Scotland personally and doublecheck about your specific model. I have a 854 and from looking at the website it seems like parts are not available but when I emailed to make sure I was told they were.

Thanks

I did email Scotland and they want me to take a measurement and picture of the elastomer. As I have a older 753 single elastomer it does not have enought space for a retrofit noleen shock.
I will have to stick with an elastomer type as it now has.

Find a local polyurethane supplier. You can get it in tubes of varying thickness and durometers and cut it to length yourself for a couple bucks.

Proflex

Maybe it's time to buy a new, or used bike. There are MUCH better riding bikes out there due to the improvements in designs. I know, I used to have a Proflex 856, until I sold it for a couple hundred dollars. A used ebay or craigslist bike can be had for a few hundred dollars if you are patient.

My 854 was sort of a "found bike". It has some nice parts on it. The frame is not my size, too large. Not too sure what to do with it. Scotland said $125 to rebuild the shocks.

Why buy a new one?

I like my Pro Flex just fine even if it has a useless suspension right now! Buying a new bike is not an option. Like I said I don't have a problem with just simply locking out the suspension if that is the best solution. I will tinker with it and see what I stumble across to do a simple retrofit if possible. I will come up with something!

Right now with me now having a new 1 year old wee one again after raising two daughters now 16 and 19 and me being on the verge of the Big 5 Oh I am using my bike mostly for pulling the trailer with my little guy to the playground or ice cream stand anyways! That is my big ride of the week typically! Ha!

Thanks for all the suggestions. I will keep riding my faithful Pro Flex one way or another!

Keep the Faith here in Red Sox Nation!

Go to www.mcmaster.com and do a search for polyurethane tubing.
