Fox Float mounting hardware help!

[madmarc]

Yup, they definitely saw you coming...

 

Aside from that, my R0.02 worth on the subject:

 

DU bushings and 3 piece hardware are the way to go. Shock mountings don't move enough to get the grease in roller bearings to move to where it needs to be, so they'll wear quickly, and 2 piece reducers are prone to flex and wear.

 

In the next week or so I'll have stock of bushings and reducers in any size you can think of at reasonable prices, I just have to get a few more bits made up. I'm also having a look at the Igus system, I'll update as soon as I've checked it out properly.

 

the 5 piece kit is a bushing kit as well. It don't have roller bearings

+1. I have installed the polymer mounting hardware on my fiancé's bike last year. It replaces the DU bushing completely, which means that you need to press the old DU bushing out ( I have an awesome tool for that job).

Funny cause it was that very LBS who wanna charge me 400 mandellas

 

No ways!!! Thats unbelievable...

Ill see if I can try find the packet tonight and show you.

 

Man thats a massive increase

[droo]

Thanx for the feedback. Please can you keep me updated regarding this issue, seems like sourcing the right bushing and stuff is a mission on its own.

 

As soon as I've got all the bits I'll let you know.

 

Surely these things can be turned easily enough?

 

JB could be putting his lathe to good use

 

Unless you're doing long CNC runs, you'll be very poor very quickly doing it this way. It's how I'm doing it now, but it's far from ideal.

Just FYI, here is the tool I use to remove/install DU bushings.

 

 

A few weeks ago I discovered that BMG sells DU bushings in imperial sizes, so I bought a few. As soon as I have some free time, I am going to see if it works.

Just sitting here wondering how difficult it would be to manufacture the 5 piece kits for all frame models. And if it would be worth the effort.

 

The Igus inserts would all be the same size for say FOX being standard eyelet size of 1/2"

The alu shaft would all have the same O.D. with either 6 or 8mm I.D. but different lengths (all FOX standard Lengths I have on a spreadsheet)

The Alu spacers O.D. & I.D. would all be the same with only the thickness to match the shaft length

"O" rings would all be the same.

 

so all I need to do is buy 1 kit to get the diameter dims. - order the inserts from Igus online and get an engineering company to turn the alu bits and get "o" rings from a bearing shop.-----Voila!!!!

Marc, sorry, I've been offine for two days.

 

Drilling 6mm out to 8mm is easy. I'm still looking for a special drill for doing it the 8mm to 6mm way.

 

As for the polymer bushings from Igus. That company is pathetic. I went to see them a while ago and they had all sorts of promises to get back to me. Squat.

 

As for using an aluminium sleeve inside either a DU bush or inside a polymer bush - that is a very bad idea. The alu corrodes on the inside and grip the bolt with a death grip. This currently happening on many Monarch shocks out there with alu hardware inside plastic bushings. It is the tightest grip I've seen in a long time and I've had to remove those bolts in a hydraulic press. I've also had one bike here that a mechanic tried to fix with a hammer. The shock mount wing broke right off the frame.

 

In my opinion, the shock eye should be protected by a DU bush and inside that bush should be either a chrome steel sleeve (like Marzocchi does) or a polymer sleeve of sorts - maybe Vesconite. I just don't know if these plastics have enough MPAs to do the job. I'll offer to experiment on someone's bike - I don't have a full sussser myself.

Fox has the hardware you need, 22mm x 6mm, cost is about R200 an end.

The Igus equivalent comprises only the two white bushings without the recess for an O-ring. The spacer (black washer) and sleeve has to be manufactured.

There is a company up the road from me that manufactures all type of plastic components from different types of plastics. The oom there is very knowledgeable on different applications. We do a lot of bushes for construction equipment linkages which are normally steel pins and bushes, and i'm sure you can appreciate the hamering they take in construction. I originally said they were crazy to change to plastic bushes but he uses some special name plastic (as long as the alphabet) and they actually last.

 

I think there are 2 very different types of applications on FS bikes.

 

1. Where the shock linkages rotate and require radial load.

2. where the shock linkages have very little rotation but need the radial load.

 

Like on my Superfly 100, the shock is very much in line with the seat stays so very little rotation on the linkages.

 

so the plastic needed would need enough MPAs for the loads and be able to rotate (no more than 90deg I would think) under load without binding

 

So i'll get the original kit from LBS when they finally get the correct size I ordered, and go see him and see what he recommends.

 

BTW my LBS who quoted me 400 mandellas per side got it wrong it's 460 mandellas for both sides. Just to correct my earlier post.

Hello, just an update.

 

I payed a visit to Mikes Bikes and they managed to sort me out! Thanks Patches for the heads up.

 

But while we are on the topic of machining bushes and mounting hardware, would Oilon not be a good material to use?

Especially because it is self lubricating etc?

Thats good to hear... sounds right then like what I paid

 

Now fit it, sell the bike and buy a HT

Ye a HT with 1 X 10 or even XX1 would solve a lot of maintenance issues
