I recently replaced the elastomer on my 2005 Klein Reve V, which has same rear triangle suspension system as the OP, aka SPA. Used a 1.25" length of polyurethane rubber tubing that I got here. I bought two 6" pieces about three years ago, one 40A and the other 60A. I didn't replace the original elastomer at that time because it wasn't in that bad of condition when I removed it back then. Cutting this stuff accurately is a real pain it the ass! Muffed up a few cuts using a miter box and saw before I figured it out: securely clamp the long section of the tube to the box, hold the other end steady without deforming it and patiently saw through it. After cutting, I sanded each cut end with emory cloth laying on a flat surface to get it reasonably flat and perpendicular. Anyways, below is what I ended with using the 60A tubing. Seems to work perfectly. BTW if you need this replacement elastomer part, you are probably far better off buying it here than fabricating it as I have, especially if you don't have the tools to cut it.
Sorry I didn't post this earlier, but thought this info might be useful none the less. BTW, I love that bike, put a Shimano 105 ten speed grupo on it about 3 years ago.
Edit: I wouldn't trust using a piece of wood as a replacement for the elastomer as discussed above. There are HUGE shock impulses that go through that shock linkage if you are traveling fast when you hit even modest bumps in the road. Thus I imagine that over time the wood may fail and it could be rather ugly when it does.

Sorry but I don't find any issues with either link, both work fine when I click on them in my browser. The McMaster-Carr link (https://www.mcmaster.com/polyurethan...~1-1-4/id~1-2/) only hits the top level product page, the elastomer I used is the last entry in the listed products, which is for the polyurethane rubber tubing. The deep link I used for it just won't navigate directly to that tubing, but the size shown is what I used. A 6 inch length, if cut correctly, will yield 4 replacement elastomers. Here's the full link for the other elastomer: https://www.suspensionforkparts.net/...fresh-kit.html.
Edit: If the clicking on the embedded links in the post don't work for you, right click on the desired link and select "copy link". Then paste the copied link into the web address bar of your browser. It this doesn't work or doesn't make sense I can't be of help.

Thank you to everyone who posted to this thread. The piece from suspensionforkparts.net is a drop-in replacement on my Klein Rêve. I really didn't want the look of the clear yellow elastomer and I didn't want to try to roll my own like Gonemad, so I used a length of polyolefin heat-shrink tubing to sheath the yellow elastomer. Net result looks better to me than clear, seems to flex as expected. A couple of hints when replacing: have an M8 bolt or screw handy. After removing the setscrew and brake bolt, threading an M8 into setscrew hole makes it easy to pull out the suspension axle. On reassembly, some silicone grease may help minimize squeaks and groans. A Philips screwdriver through the brake bolt hole can assist in lining up the axle.
M8 button-head cap screw threaded into suspension axle makes it easy to remove and re-insert.
New elastomer from sfp wrapped in black heat shrink tubing. Old elastomer for comparison.

Did your local Trek shop replace the bumper with an actual Trek part (from their discontinued Trek Pilot road bike)? Or did you bring in your own, like suspensionforkparts(.net)?

I;m not sure. I did not provide the part. I don't believe it was a Klein NOS part. Must be from the TREK inventory of parts. I can find out and let you know.

If possible, please post a picture of the new part, and please let us know if Trek are supplying parts again, or if your local shop used an alternative.

Thanks for the picture - this is the same replacement I made on mine. I didn't like the translucent yellow color, so before I installed it, I wrapped it in black heat-shrink tube.
