Worn rockers… for the bin?
Just ordered some replacement rockers (and a full pivot rebuild kit) for my flux from Greg @ turner. I’m in exactly the same boat. 🙁
Still, we’ve had about 5 winters’ worth of mud in the last 18 months, and I’ve ridden a shed load of miles, so it’s a case of suck it up I think.Posted 4 years ago
Hmmm…. sounds interesting. I’ve ordered a pair of rockers from Silverfish, but may give the shims a go on the DW-Links when they go (which I’m sure is going to be pretty soon, they’re *only* £120 a set) 😯
The missus is going to kill me, saving for wedding isn’t being helped!
@Samunderhill – How much did Greg charge for the rockers Sam?Posted 4 years ago
I’d not be using the threadlock as a filler, it’d just be to hold the shim in place. Any machining would be to get the right diameter for the bolt to fit through, the closer the fit, the less chance of movement.
You’d want as much of the bearing surface in contact with the shim, as it would distribute the load better.
You shouldn’t need to bend the rocker out if you use the right size shim 🙂
I’ll let LoCo give a proper engineering response though 😉Posted 4 years agoMacgyverMember
ahh, had a similar thing with the main pivot of a Mk1 Yeti ASR. Over 10 years the bushings wore the main frame just like your rockers. Ultimately a friend machined a new oversize bush for me on his lathe but the stop gap method was shims cut from coke/tonic cans with a beam compass/scapel. Worked quite well too althought fairly soft aluminium so lifespan was short in muddy weather. Cheap to replace though and a good excuese for a G&TPosted 4 years ago
I’m pretty sure these are for the emergency spares box, but what do you reckon to the rockers from the 5-Spot? They mate up to bushings, and obviously they’ve been run dry, either by being pressure washed during their life, or not being greased up.
There’s play in both sides, on the rocker tip, and at the seat tube pivot 🙁 New bushings would fix the problem, but I’d need to file down the new pivot itself, as the wear means the bushes sit *in* the rocker arms…

Have a look around the web and you will find this is a common problem on certain DW linkages. A friend has the same problem on his Iron Horse Sunday. Its a terrible design flaw that they changed on later models with a revised linkage.
My mate solved it with some custom plastic washers but they don’t last long. I think he has given up trying now and just accepts the play and will ride it until it dies.
When you look at the design it obvious what was going to happen. What were they thinking putting it into production.
Another friend has suffered a similar problem on the back end of his carbon lapierre Zesty. Again terrible design which we solved temporarily by cutting some shims from an old milk bottle.

Well… I don’t agree with that statement. The kevlar bushes should wear a lot faster than anodised aluminium, that’s the point – the bushes wear, the frame doesn’t. This works perfectly well for shock bushes.
The problem is when they’re not lubed, so friction is increased, which will eventually cause wear. It just takes some numpty to pressure wash the links, or to not follow simple maintenance routines for this to occur.
I bought the frame as a third owner, so absolve myself of all blame 😉Posted 4 years ago
