I own a Klein Reve with the s.p.a. soft-tail suspension w/ BASF elastocell spring. I am getting quite a bit of noise from this shock lately and wonder if anybody knows how to take this apart, or what the problem might be. A trip to my local bike store left the mechanic stumped as to how one could take this apart for cleaning or lubing.

It's been a while since I've put one together so some of this may be a little off...

1: Look up from the rear dropouts towards your rear brake. there should be a little set-screw in the crotch of the seatstay junction. Remove that with (I believe) a 5mm allen wrench.

2: Remove your rear brake

3: Again, looking up towards the brake hole from the dropouts, you'll see a metal shaft running up the monostay into the elastomer. That needs to get removed. The easiest way to remove this is to thread a bolt into it (it'll thread into where you removed that set-screw) and pull. They can be a rather tight fit. I believe the thread is M8x1.

4: The elastomer can now be removed. You may have to spread the frame apart a bit to remove it.

I reckon you could use a standard citrus-type degreaser on the elastomer to clean it. You shouldn't have to lube anything. I do sometimes lightly grease the shaft (that you removed in step 3) to assist in going in, but it's certainly not required.

Hi, do you have information on where yo get the Reve's elastomer spring for replacement with a softer or harder one, depending on your weight and riding style...

I had the exact same issue. My LBS thought it was the SPA but didn't know what to do about it. With the help of this page (and an email to Trek), I got an exploded view of the SPA, took it apart, cleaned it, replaced it, and now the rattle is gone!

Hi

Just wanted to say thankyou to the people who posted on this thread. Especially the post showing the exploded diagram. Managed to remove and clean the SPA on my 2004 Klein Reve.

Re creaking noises from this bike. I have found that if the rear wheel is not properly seated in the dropouts you will also experience a creak when peddling. Make sure the springs on the rear wheel skewer are the correct way around.

thanks again

Thanks to previous posters for diagram and removal instructions. I'm trying to replace my 14 year old bushing with the Klein replacement.

I've threaded the correct M8 bolt in the pin, but am unable to pull the pin from the rear stays, using channel locks. Pin appears to be frozen in carbon stays, and I'm afraid to impact/hammer bolt in fear of cracking stays.

I've dripped WD-40 on end of pin. I don't own a puller that would fit this job.

Were you able to apply enough force to directly pull the pin out, by just grabbing and wiggling the head of M8 bolt ?

Any suggestions appreciated !

Thanks.

Update -

Trek shop was able to remove old bushing and frozen guide pin. Initially, He could not remove pin by pulling/hammering on M8 bolt. He finally succeeded by locally heating the frame, which expanded the diameter enough to free the pin.

He didn’t lubricate before reinstalling, so now it appears to be the source of squeaking. I need to disassemble, grease, and hope this resolves.

I’m a little confused by previous poster comment on noise from backward skewer springs. Yes, they need to be correct, but I don’t see how that could cause noise, if wheel skewer is properly tightened and locked.

Backwards springs can get feckered up and pinched by the QR ends causing a less than perfect clamping surface and potential squeeks.
