fox RL100 vs Mazocchi Marathon Corsa

[wheelz]

Hi guys

Which do you rate is better and why?

thanks

[Bike Mob]

Fox everytime

[Daxiet]

I would go Fox, just consider Mazocchi a bugger to service from what I saw on the fork service workshop.

Both forks are great. Buy the fury brown animal, Marzocchi don't have the best back up in SA.

I just bought a mx race  2006 from a friend.. the fork has a bit of a history.. He brought It and used it for about a year before It got stollen (allong with the rest of the bike that was attached to it) the other day he was riding down the road when he saw some guy riding his old stollen bike, so He stopped told the guy to run .. and the guy did. another 8 months later the fork is mine, I put some prep grease on the stancions and the fork runs as smooth as the day he got it.. Id say its nicely run in..

 

These forks have been made as simple and "uncomplicated" as possible. the fork is very very sensitive to small bumps but does ramp up a bit quick, so I guess open it up, throw some oil out..(which was still clean after about 3.5 years)..

 

I cant speak for the corsa.. but In my experiance the Corsa wil outlast the Fox by a decade.. Its very stiff and weight probably the same.

 

We all know fox.. very plush but also very technical forks ( I meen the internals of those things are seriously complicated..they do work well, they are easy to adjust ( Im sure the corsa dont need oil heights changed for bottomout annymore)

but, Fox seem to need new seals everyservice which seems to be around yearly..

 

Im really not sure which Id go for, but If you feel like being different,  Go for the bommer

So get a SID.. Im serious

I see we are one in the same I have an SID WC, old version, in Athena White. 1298 grams, with Pushlock, on the scale with no modifications, standard mix of 5 and 10 wt oil. Super Plush, easy to fix and the spares are readily available and well priced.

thanks guys. Im looking for the best xc fork-that i can offord. Iv had my fox for about a your and no complaints but just got a mazocchi marathon to see whats its like. Iv always wanted a remote lock out(on the handle bars) and am considering going to a 80mm (fox is 100).

Racer X-what year is your fork? Iv always liked the look of the SID's

Well it was bought and sold in 2009. They were discontinued in mid 08. Racer X2009-08-27 06:41:03

This is a common misconception, fuelled by bike magazines who don't seem to understand the difference between the spring and the damper.

 

The fact that the Fox ramps ups as quickly as you state, has to do with the airspring, not the damper where the oil lives.

 

Air springs are non-linear - the 1st kg moves it X millimeters. The second kg moves it X-1 mm and the 3rd kg X-2mm etc etc.

 

No matter how much or how little oil you have in the damper, it will not affect that characteristic. The positive/negative pressure spings are an attempt to get rid of that annoying characteristic of air forks.

 

Steel springs on the other hand are almost perfectly Hookean. In other words, for a given load, it will move a given distance throughout the travel of the fork.

 

Something else I often read in these mags is the attribute of "plushness" to this or that type of spring. It is impossible to perceive whether you are compressing an air or steel spring. The small aberations in travel come from dirty or sticky seals, not the spring.

Ja ja  Johan that might all be true and If youre saying the Marzzochi is just as complicated than a fox.. I know Im not going to win a argument against you  and that wasnt the outset of the post. BUT

 

The airfork ramping up thing..

I was compairing apples to apples. Air fork with airfork and the Fox and My Rock shox is definately more Liniar than the bommer

 

As for this....

 

"No matter how much or how little oil you have in the damper, it will not affect that characteristic. The positive/negative pressure spings are an attempt to get rid of that annoying characteristic of air forks."

 

I went to the shop, we poured some oil out and it wsa immediately better, so you cant make statements like that, Its common knowledge that with bommer forks you have to  "play/test" with oil height to get the compression damping right for you.

 

Sorry for losing sight of the topic here..

Id still say buy the new sid. Fox's are very expensive, and I think RS lasts better.

C'mon, just because this is a request for opinion, it doesn't mean you can throw in confusing technical bits and then backtrack under the guise of opinion.

 

I made no value judgement about either fork, I explained an aspect of springs.

 

Back to your proof that air is Hookean....

 

The fact that the fork performed differently after you removed some oil is easily explained. If you overfill a damper you will experience something like severe ramp-up but what you are feeling is the oil chamber filling up with a volume of oil equivalent to the volume of the damper piston rod. This rod (sometimes referred to as the compression rod) enters the oil chamber and the space it takes up has to go somewhere. Usually it is absorbed by compressing the air above the oil level. But, if this is too full, the fork will suddenly go hard. To the untuned observer this will feel like air ramp-up but it isn't, it is more severe and can pop a seal and blow oil everywhere.
