Hi guys,

I have a Mondraker Summum 2017 wich came with a Marzocchi 380 CR.Most probably it came equipped with a 6.5 spring which I believe is soft or standard and is suited for an 160 lbs rider from what I was told because I can't find online any chart regarding spring rates correlated to the weight.I am heavier (195 lbs) and I have a hard time finding any retailer across Europe selling replacement parts for this fork.I also read that 380 and 888 forks share the same dimensions regarding the spring.Also, I read that some Fox springs seem to work.

Guys, I need some help.
Thanks in advance!

Fox 40 springs definitely work. I've used them, i'm 110 lbs and used the purple spring.

I found this one:

It seems that the spring it's compatible with models 2012-2015 and my fork is 2017.Should I fear any incompatibilities between this one and 2018 models?

Hi, first off awesome thread, been right through!

Recently purchased my first pair of 380s, coming from a long line of 55s and BOS Idylle SCs.

I have given them the obligatory strip down and inspection, they are immaculate but top caps were insanely tight, needed my 2ft breaker bar to undo them! Cringe!
I need some help here tho - the springs it came with a random.

It was fitted with a steel Triumph motorcycle spring, really its ridiculous!
The 2 spares I have appear to be both Marz Ti Grey colour code, looking back is this Marz extra firm?

I weigh 180lbs geared up, so would think I need a medium??

I don't do massive hucks etc, I'm into suppleness and speed, but want a solid mid stroke.

What do you reccomend and does anyone have a Ti one they are willing to sell?

Cheers, Dave

Quick one with the top caps, did you loosen off the pinch bolts on the top crown first?

Oh yeh, the top crown wasn't even on the forks! Couldn't believe how tight they were, Luke someone had gunned them on!

hello, i've just bought mz 380 C2R2, and I 've realised, that HSC "button" turns without "beginning or ending". Is that very serious issue? Except of that, I can not tune it properly, since I have no idea, what setting ( if there HSC works at all) is set actually. Thanks

Most likely, the thread of the compression unit shaft is busted, i know this because it happened to me.

Thanks, does the recent condition ( if you are right) somehow seriously affects the fork? Because it feels fine.

Not really unless you want to tune the compression. I'm 110 pounds so i run the lightest spring with no preload or compression. I only tuned the rebound.

I have just realised, that LSC works with starting and ending points. Is it still the same story?

I would take it apart and see for myself, i think the LSC has an independent thread.
