How forked is your fork?

[Odinson]

So, regarding the whole Brunox debate. I performed a lower leg service this weekend and this was the state of the foam rings: 

 

 

I've had this bike since Jan '17 and this was the first time pulling the lowers off. I also apply Brunox to the outside of the seal after every wash. 

 

All in all, I honestly don't think that the Brunox mucks up the seals/foam rings.

Your experience ... my experience looks like this 90% of the time, sometimes worse!

 

Without a doubt, not the way your foamrings should look or the way it would look if you didnt use that little black and orange can of snake ...

 

As Simon would say, the evidence is inconclusive.

T-man. I'm no Brunox evangelist. I'll stop using it and have a look during the next lowers service what the condition of the oil and foam rings are. Will be an interesting comparison.

The foam dust rings on the inside of your fork are suposed to be kept "wet" by the oil in the fork and keep the stanchions lubed with said oil.The rubber seals on top are meant to keep gunk and dust and sh@t out of the fork.

 

In many cases "lube" sprayed onto the stanchions on the outside of the dust seal will only help dust and gunk and sh@t to slip past the seals and get stuck in the foam rings wich in turn will rub on the stanchions and cause the dreaded stanchion wear.[emoji33]

 

That is why many fork/shock manufacturers discourage against the use of outer lube product and rather encourage regular fork/shock services wich include replacement of fork oil, foam rings and dust seals to reduce the risk of wear on your fork/shock.

Mattoc. Unless you need a 29er more than 120mm. In which case meh.

 

Honesty the 2nd best fork I've ridden beside my 66

 

I believe that the 120mm model is in fact adjustable to a distance of 140mm quite easily. The price does not seem as enticing as the 27.5 version was. One hopes that Chain Reaction Cycles will have some special offers on 29 versions.

Cool man, just have a closer look at your foamrings. It kind of looks like there are black spots starting to form and they might end up looking like the ones in my example given some time.

 

In the example I used above, the fork was not serviced in two years and the owner started using the external lube little over a year back.  My guess was that the foamrings were bone dry when he started using the external lube, which made things worse.

 

In my opinion the combination Rock Shox Foamrings and external lube is a far worse than that lube combined with Fox foamrings.  The Fox foamrings are much more dense and retain their oil way better.

 

Far too often when I open a Rock Shox up, the foamrings are dry.

Two lowers services in and my foam rings look just like yours despite using Brunox frequently, but conservatively.

 

Two people essentially driving this thread. Both are being equally ridiculously stubborn.  I'll go with what Droo said (besides he did the last lowers and he wasn't particularly alarmed).

So to me it sounds that often it's actually just owner neglect f'ing up their rings, which then creates less ideal environment to be using stanchion lube (which is not meant to replace fork oil as a lubricant, but rather in minute quantities as a cleaner - well that's how I use it anyways)?

[Sean Hammon]

LOL, that's like saying it's OK to put sugar in your petrol tank, because the owner's manual doesn't explicitly say you shouldn't.

 

I support the use of a stanchion lube, but I also know that most of the 'developed' products are cheap gun oils in a fancy tin (with a fancy price). 

 

You can be sure that if the thieves at FOX could sell you stanchion oil, also at R1000/l, they would. "Snake oil" IMO is apt.

I believe that, as with chains, dust and grit stick to exposed oil. Oiling stanchions is begging for grit and dust to stick there, hang out there, and grind the stanchions and seals away. Every stroke becoming a grind. There is more than enough internal oil and oily vapour going on inside to prevent dry dust seals.

"I always felt like I was doing my bikes a big favor by using Fork Boost, and it certainly hasn’t produced any negative effects on my fork’s performance. If you’re looking to keep your forks clean and running smooth, I’d happily recommend Fork Boost."

[Odinson]

Which fork ?

 

And if you had to make A rough guess how may hours ?

 

Dude, never even saw your reply. 

 

It's a RS Lyrik RCT3 2016. 

 

Have no idea i.t.o. hours, but probably far over the recommended 50h interval. 

[The Bull Shark]

BTW, I thoroughly recommend the Charger 2 damper upgrade. Also, through trial and error I can also recommend a healthy dose of SRAM Butter on that air spring. My Reba is oh so smooth now.

[Dirkitech]

Problem is that most people do not do the 50hr service, which is quick and should cost in the region of R650-R850.

 

By the time it does get serviced, it is too late for a 50hr service and seals, dustwipers must be added.  Fox Dustwipers are R665 at the moment.  Then you are up to R1300 quickly.

 

If the 50hr service or lets call it a "lowers service", gets done regularly, you would not need to replace dustwipers that often. 

None of the lbs's I've made use of for servicing forks (at least 4)  offered a "lowers service". They've only ever allowed a full service even on request...
