Not true. I know it goes against the 'accepted' here, but there is nothing about titanium that makes it any different than steel as far as its use as a spring.
You could argue that it is less sprung weight, but that is very minimal, and varies with coil movement of said spring.
I think that a lot of what people are feeling is a 'true' spring rate. Most, if not all, steel bike springs have a huge tollerance. Meaning that a '500#' steel spring could test out to be 430# or 570#. Because of the nature of the ti spring biz, they hold much tighter tollerances, thus your 500# ti spring will be 490# to 510# for example.
Ti is used for one of two reasons mainly.
1 'it is lighter'
It is less dense that steel, and has a similar or higher tensile strength, allowing less material to be used.
2 see 1
because of the properties above, ti can be used to make a spring that will fit within certain physical paramaters (free length, diameter, pitch, travel, etc) that might be impossible with most steels.
It also has a different natural frequency than steel. So, in an application where a steel spring might resonate, a ti spring with the same phisical properties (length, rate, diameter) will not.
Dont get me wrong, I have ti springs on all my bikes, but in this application, the ONLY advantage is weight. (OK there might be a scenario where a very high rate spring is needed and only ti could fit the free length and travel needed for the shock)
If you want to know about ti springs listen to DHRracer, he knows....
I hate the width of this thread.
That being said, I wanted to comment on the Z1 line. After looking at the AM line and the 66 line, I do not see the point of having the Z1. Can someone point it out to me?
yep, id probably not buy a fork for nostalgia, but there probably is an group of people where that element could be a deal maker, i mean, i dont think they are thinking to sell it based merely on nostalgia, its got its own credentials, but for sure its going to have a special appeal to some people and thats what a broad product lineup is meant for.Nostalgia doesn't seem to be a very good reason to produce a product meant to be used. But, I suppose there must be that demographic out there that's willing to buy an anniversary version or Marzocchi wouldn't have produced it. I just know that my first was a '99 and while it was cool (and electric green), in no way do I feel nostalgic enough to buy another one just because it looks like my first Marzocchi. I buy based on performance and price, not feelings
A lot of it appears to be interchangeable, tooWelcome to the uber-redudancy of the Marzo fork line.
the difference is the coil spacing vs windings, where the low wind count of a Ti spring causes a coil to have a much higher displacement. Coils transfer this displacement into torsion which in itself does not have a 100% linear relationship (i.e. one inch of coil compression does not equal x-degrees of coil twist, it will vary). So its not a function of the metals (both are operating in the linear elastic range), but rather by coil geometry (like using prog winds to mess with rates). I dont know how much of this effect would actually be felt, but its a theory at least.....Not true. I know it goes against the 'accepted' here, but there is nothing about titanium that makes it any different than steel as far as its use as a spring.....
what about pre-2006 888s?Well.. Here is an update.. The Ti springs on the new 888 will be able to go into your 2006 888.... Product knowldge meetings are fun...
Brian
Maybe - but I bet you don't see an 888 shaped like an L.... but I still don't think theres ganna be a fork as good or as light as the boxxer WC
Not that I can see... 06 dropped a pretty good chunk of weight from 05..
Brian
The word I am hearing is 150g..Brian can you tell us exactly how much weight would be saved running a ti spring in the 888?
Brian, whats my fortune today?The word I am hearing is 150g..
Brian
Mosty likely at some point...Brian - any chance that the 07' silver stanchions will be available to buy as a spare part?
Neither do mine...Wow, my threads never get this many posts.
I would guess a 888SL would be a better choice...Brian should i buy the 66 sl for my gt it-1?
Jeff... Only you get ice cream you sexy biotch....LOLBrian, will you take us for ice cream? And one of your special emails?
why's that. I'm looking more for versatility than straight up DH.I would guess a 888SL would be a better choice...
The TST Roco rides like a WC when the TST is off...Can I get ice cream too?
I actually have a technical question about the Roco's. Thought about starting a thread.. but this is easier.
I have a Roco WC on my Sunday which I friggin love. And am thinking about getting another one for my trail bike. Does the TST shock have the same internals as the WC (i.e. when it's open does it act like a WC or is it more like the diff between the RC and VF)????
I also heard the Roco Air can have a platform by removing the negative air. Is this also user - servicable? Is it adjustable?
Thanks.
