proflex 756

[fyrstormer]

In the long run you're really better off just buying a new fork and a Risse shock for the rear -- or a Noleen shock in good condition, if you can find one. I upgraded my 756 to a Noleen NR-2 in 1998, and put a Manitou SX-R fork on it in 2003, and never took a second look at the old elastomer shocks. If they worked better than springs, they would be worth refurbishing, but they don't.

Keep searching for some ODS shocks.  They will enable you to convert to springs without breaking the bank.  Meanwhile, keep up the search for elastomers.  Depending on what tools you have, you can find and check springs and elastomers for suitability.  A bathroom scale and a tape measure will reveal spring rates.  Suspension bushings can be made less linear by trimming them to a cone shape to change them to rising rate on rebound and compression.

Hi again guys.. the rebuild is coming along nicely.. I've had a scout around on here, but no joy.. does anyone have a scan of the Vector 1 fork manual on here?.. I was a bit hasty stripping it down and I want to make sure everything goes back in the right place!
cheers.

there doesn't appear to be anything specific to the vector 1 fork... Is the only difference between vector 1 and 2 the ods shock?

[fyrstormer]

I remember back when I had the original fork on my 756, I called K2 and asked if there were any upgrades available for its shock, and the answer was basically "no, your fork is too old and it uses a non-standard shock length, we never made an updated shock for it, we just built a new fork around a standard-length shock instead." Maybe you'll have better luck than I did, but if you don't, you're really not losing anything by switching to a newer telescopic fork -- they've improved dramatically over the past decade.

I've got some nice Pace carbon forks sat in the garage that will look lovely on it.... I just want to see what the original ride would've been like... plus I think it's the vector fork which makes the Proflex stand out as one...... hmmm ...

When I ran the elastomers back in 95-98 I never had any complaints about their performance as long as they were maintained they worked quite well. The only issue I have ever had with the linkage fork in general was their lack of travel. I now own four linkage forks (six in all) that have five inches of usable travel and that works just fine for cross country riding in my opinion.

I had a pile of parts and a bunch of inoperable squishies so I put together some ODS shocks and springs to replace them.  I am very pleased with the result.  No, not a lot of travel but then I started out having a great deal of fun with no suspension.  I've always been one to make the most of equipment with the least $$.  For even greater fun I do have to pick my victims, older, fatter and slower to be sure.

Is that 5" of usable travel between 6 forks, i.e. all of them added together? <GRIN>

I though the maximum from a CrossLink was 3"

How have you got 5" or is it some other linkage fork? ( I have a couple of sets of Fournales, but I'm pretty sure they only do about 3" as well.

Interested............

Yep, five between the six of em --- 

I have three of the AMP F4BLT linkage forks that now provide five (well very close to five) inches of travel and a modified Look Fournales fork that is working thus far with a tad over five.

If the Look continues to work a while longer without blowing up I will happily supply the info on making the change.

My crosslinks are confined to three inches of very plush travel though and work very nicely with the Risse shocks.

Aye, Fornales are 80mm..........just over three inches- be interested to see what yer mod is.
I still think elastomers are a good idea for short travel, if they are durable enough- almost zero maintenance, no seals or stanchions to get FUBAR'ed.
