Does it mean that the rebound is way too fast, or the suspension is not going down, or what?

QUICK QUESTION: What does "spiking" on a fork mean
- Thread starter oreo321321
- Start date
When a fork can't compress fast enough for a hit and kinda "locks"
"locks"?
So its kind of like the fork not being ale to soak up everything? or like it doesn't have enough travel?

my GFs forks were great until she found out about spiking, then they suddenly became crap....
It's sort of like that. This is a problem that lots of lower-end forks have, due to outdated damping circuits. Most forks that do this only have a small oil port on the bottom of the oil cartridge that allows oil to flow in and out. Under extremely hard hits (where the fork is compressing all the way very quickly), the oil is traveling so fast that it can't make it out of the port fast enough, causing the fork to feel like it's out of travel momentarily.
More like the fork not being able to soak up anything, for a short period of time. I beleive bad "spiking" can be a warning of, or lead to cavitation(complete, unexpected lock-out) that usually results in blown seals (see: 2003 Boxxer team and World cup, pre-Romic tech visit...).
I want to get this kona stinky that has a 2003 Jr t on the front, and I have heard things about it spiking, so thats why I asked.

Yup. Although not as bad as last year's boxxers, that fork does do it occasionally. Just ride slow and it won't be a problem.
ride slow...
My understanding is that for hucking and jumping you really don't notice spiking, it's just when you're going down those gnarly fast rock gardens with repeated big hits the fork can't react fast enough. Without getting into the gory details your fork will kind of lock out spontaneously or at least it will feel that way. It's kind of like brake jack only on a fork and without the necessity of brakes.
another side effect is it can be quite hard on the wrists
Can I drill the hole bigger? so it let's in more fluid, so it doesn't spike?
only if that hole is in the side of your fork leg, in which all the oil will pour out...then yes, it wont spike then.oreo321321 said:
but otherwise, drilling a larger hole wont make it perform like a fork thats normally 300$ more expensive....

i fixed the link
if you were to drill the hole bigger, i would assume it would fvck with the fork's compression stroke by speeding it up. just get a good fork in the first place and your set.
As I Will Say It Again, If You Don't Want To Listen To Me, Or Answer My Questions, DON'T, There Is Nothing Forcing You To Read My Posts, Or Even Talk To Me. If Your Not Going To Help Me, Just Back Off, I Don't Want To See You Ever Posting Again In My Threads If You Are Going To Waste My Time, As Am Not Wasting Yours, Because You Don't Have To Read My Posts.
Yeah, I won't drill the hole, I was just wondring if that would work.
This thread will be closed by the end of today.
I've tried to be nice to you because you're getting a lot of harassment from everybody else but you never fail to come off with a post like this and make yourself look like a complete imbecile. Obviously you don't know much about bikes and that's why you're asking here, when you insult those who do know a lot because they don't tell you exactly what you want to hear that's really unexcuseable. When people respond with technical reasoning in their posts it goes over your head, when they respond in plain english you think they're patronizing you... What do you want, I think I'm going to have to agree with the others at this point, you need to go elsewhere if you're not capable of reading and responding to posts in an educated, mature fashion.oreo321321 said:
Again people here make a point of reading every post, lots of people see your pitiful understanding of bikes and want to help you. You then quantify their knowledge with irrelevant metrics like how many feet to flat they've dropped and you cross over into the realm of childishness.
I've already said once and I'll say it again, Jr T's are known to spike, some people are really bothered by it others aren't. I ride with a guy who has a junior t and he says that he knows his fork spikes but he really doesn't mind, it only does it on fast downhill sections and the majority of his riding is slow technical hucks. This guy goes just as big or bigger than guys on super t's and shivers, believe me a Jr. T is adequate for lots of people, if you've got the money there are better forks out there but it sounds like you are short on cash so just get what you can afford. You can drill out the rod to reduce the spiking, this was a popluar mod on '01 and '02 forks, but doing so will only make the spiking issue slightly better while the overall performance of the fork will suffer. If the only type of riding you do is fast downhill stuff with lots of gnarly chunky stuff get a Jr T and drill it out, if you do slow speed hucks and stuff get a Jr T and don't drill it out, if you do a little of everything just get a Jr T and leave it alone, ride it for a while see if you can tolerate it, if not sell it and get something else.
From the sound of your posts you are nothing more than a virtual hucker who doesn't have the skills or the money to really need a bike like you are looking for. Get what you can afford and let your skills catch up.
Thank you!Kornphlake said:
the problem with drilling is it bypasses the real culprit, which is a crappy check valve that doesnt allow very good flow in the compression cycle. By drilling a hole in the lower compression rod, you may instigate too much flow through the pumping rod and not enough through the valve, leaving a void between the pumping rod and stanchion (the volume that creates the rebound damping). So you may end up getting cavitation, resulting in slurpyness and now crappy rebound damping as well.
I've tried a series of mods and what can actually happen is unpredictable. I suggest you trust marz has pushed the SSV(F) dampers as good as they can get and just leave them alone. The best mods are done to the SSV(F) valve, but again they are unpredictable and not for the uninitiated.

First of all, that post I made before was aimed at the people who are being a$$holes. Excuse my language. That post was not meant for the people who are being nice, and helping me, I appreatiate their help very much. So don't take that post the wrong way.
The guy who owns the Stinky said that the Junior T does not spike at all, and never did, so that's cool. He's a bike mechanic, so he proabbly knows what he's talking about. I would never take the chance on drilling the hole bigger after listening to you guys, because it would be way too risky, thanks.

bike mechanics dont necessarily know ****....or he's lying to you.oreo321321 said:
now that was unpredictable...Jm_ said:ahh, so it'd work like a boxxer?neaky:
Either or. Junior T's, or any fork with SSVF valving, is notorious for spiking. They all do. Every Junior T that I've ridden (grand total of two) has spiked in rocky sections. There is no way around it.zedro said:
I won't nessisaraly be taken hit after hit after hit, because I am not going to race with it, just freeriding, so it shouldnt happen that often or at all for me then right? (under those conditions)

The guy you're buying it from may not have ever noticed it spiking because he didn't notice it. A lot of people don't notice the subtle flaws in thier bikes until somebody points them out.kornphlake said:
People like Jr Ts for two reasons;
One, in the parking lot, on the showroom floor, and at 5mph, the Jr T seems just as plush as ANY marzocchi, shiver, mosnter T, etc. As you speed up, the forks greatly diverge though, the Jr T just feels worse, the other forks feel just as good. "I just gave a good push-test to the Jr T on this bike, and the Super T felt EXACTLY the same! Why should I buy the Super T?"
Two, it's usually the first long travel fork that someone uses, they immediatly think that the Jr T is as good as it gets.

If all you are doing is drops and DJs, yes, it shouldn't be much of a problem. But every time you go fast through anything rough you're gonna feel it.oreo321321 said:
Kornphlake, the owner is a bike mechanic, so he rides bikes all day, and fixes them. He said that he would never sell a bike that spikes, so I'm pretty sure he knows what spiking means. He also said that he likes to downhill, and he said that there has never been a problem with spiking on any of his runs.
