Fox will rebuild Shocks and add the SPV valving.

[Curtis]

Just herd from The Bike Zone here in Ontario that Fox has a program that for $125.00 they will rebuild your shock and add SPV valving, turn around is estimated at 2wks.
I thinking I'll go for it sounds like a good deal to me. Any other thoughts or info on this.

[trail worker]

be carefull that they havn't mixed the SPV valving up with say something like propedal or "big-hit" valving.
i don't think they are actually allowed to do SPV type upgrades on their shocks..it probably has somehting to do with copyright infringement yada yada yada.
wether or not the fox shock body can house such upgrades is another story altogether which i'm entirely unsure of.

I hope its possible to get propedal added.

[hampstead bandit]

don't see how that would work its not as simple as changing the spring stack? surely the internal would need to be pretty different to accomodate the SPV mechanism, you need air in there (??), etc.

the pro-pedal mod is great, here in England we have MOJO suspension (the guys who do the Fox internals for Boxxer / Shivers forks) who do their own version of pro-pedal with no low speed bleed off and rebuilt shim stack with heavy initial resistance...works like a dream had it done to my 02 Big Hit. feels slow rebound, but suddenly opens and is very plush, pedal quicker and suspension smooth as...

It isn't SPV, thats a licensed term of Manitou's and I beleive Progressive.

Fox uses "ProPedal" which is basically a threshold type valve on the compression circuit to filter out pedal induced bob. Initial reviews on the ProPedal have been excellent, with some prefering the feel of it more so than the Swinger and 5th, due to ease of set up, and pedalling performance without sacrificing bump performance.

As per their cabability to handle the upgrades? I have dealt directly with Fox USA and the service I received was outstanding. When I dealt with Cycle Works in Edmonton and the outlet back east, i was not overly impressed.

Fox has been in the suspension game longer than anyone else, and they have remained a key player for good reason. Its great to see other manu's pop up and offer competition, that drives product development and diversity. I would bet that they are capable of meeting the level of service they have promised.

Sounds like a worthy upgrade to me.

Just talked to Cycle works.........."nothing at this time. But they maybe working on something, check back in the spring."

heh i beg to differ. i hadmy shock in recently (last week) and they had a great turn around. it took them a mere week to rebuild my shock and install the big hit valving. all of this done for free(under warrenty of course wanted to get the last little bit done that i could before warrenty runs out)

i quite liked the services that i recieved at cycle works. they diid a good job and treated me well and thanks for reminding me i need to call them and thank them for there speedy service.

Is the valving a noticable change?

Thats good to here...Maybe they have tightened things up over there. In all honesty, I dealt with Velo Cycle, and was less than impressed. They lost my shock and gave me someone elses. Not too cool, but I understand shit happens.

The valving change is indeed noticeable....Its worth the coin for sure!

i dunno yet. my shock is sitting on my work bench and the bike is in a pile the shed floor lacking a fork and shock. when i get it back on i will let ya know

[HopHead]

I am familiar with the new ProPedal concept......but speak more of this "bigHit" valving!:???:

[IFO]

yeah, i bet the SPV valving u heard about is the new "Propedal" circuit...

and it should be able to be put into a older RC as the new 04 propedal RC looks just like a reg RC....

i'd for one rather have a "propedal" RC then a 5TH/Swinger....

im totally happy with my FOX's feel/performance...

[damian]

So are "Pro Pedal" and "Big Hit" valving the same? Is the big hit valving some kind of stronger upgrade? I like the sounds of Mullets description about the Pro Pedal, it sounds sick...How much does it cost to do? I'm really interested in it...I cant fit anything else on my Shore, and upgrading my Fox RC sounds like a great option.

[bighitter]

older fox rc's had "kidney bean" shape ports, on big hit's or impacts the valve shim could get sucked through the valve port.the "bighit" kit includes a valve with round ports so the valve shim has better support and can't get suck in.

pro-pedal is well explained above.

[Rat]

so my shock(RC) is making progressivly worse sucking noise and im told it needs to go in for a rebuild. what should I ask for?

a six pack and a pound of yay. get the party started.

[IFO]

"Pro-pedal" adn "BIGHIT" valving are not the same thing...

but i think u can get both features in a new shock or a rebuilt one if u paid extra for it....

good luck....

I tried a re-valved Van RC shock for a while (basically Propedal before that was available as a stock option) although it did improve the pedaling, it's small bump sensitivity suffered as a result, and the shock was a lot slower.

When I went back to a stock Van RC I really noticed the difference, although there was far more pedal induced bob, the shock was far more sensitive and much livelier - I guess it depends what kind of riding you do, racers tend to like this type of valving, but for me I'd rather deal with the bobbing if it means a better feel.

[Curtis]

I think I'll do a bit more research before I send it in. I like the way my bike handles right now, pedal bob is not an issue, I have a smooth pedal stroke so if it does exsist I don't feel much of it. I don't use my bike for racing and like a few oters have said, and what I've read you lose some of the low hit feeling of the stock ste-up.

[Demonic]

Im sending my RC back for warranty. I asked if a pro-pedal"upgrade" is an option and was told NO ( by fox usa). Maybe a while back it was an option, but now it seems like they arent doing it. I read on Ridemonkey that fox has a new setup for pro pedal that is completley different and the shocks that were possibly "upgraded" arent 100% correct.

[Rat]

So what exactly does the big hit valveing do. add more compression ?

[Oldfart]

Pro pedal is Fox's version of SPV. Terralogic is the inertia valve thing. Different things. I don't think the inertia valve thing will go far. The SPV is IMHO a better way to control excess suspension movement. I'm digging my Manitou Minute 2:00 that's for sure. Its 100mm version on a Blur with the 5th Air out back. Its funny, it rides firm, but its not. I'm getting all the travel, I bottom now and then, but it doesn't feel at all harsh. But it pedals firm so the bike handles well. Less brake dive, doesn't dive as much when cornering. I like it.

[hampstead bandit]

So are "Pro Pedal" and "Big Hit" valving the same? Is the big hit valving some kind of stronger upgrade?

nah pro pedal is re-shim job?

and the big hit valving i heard they changed internal parts like valve piston, shims,etc.

also on the 03 and 04 Big Hit we get them with Van RC here in England they had pro-pedal valving as standard

we have Mojo doing their own mod that rules. thats the one i had done


its the best GBP£50 i ever spent getting the Mojo mod done

[Curtis]

Pro pedal is Foxes response to SPV and Big Hit valving is just that, valving changes more condusive to big hits or sudden impacts. There are some very informative post on here about that read back a few post and you'll see. ;)
