Fork Problems

dadude456

I have a problem with my suspension fork.

Basically, by hanging it off a wall hook at work on the front wheel, the suspension has loosened itself from the fork, meaning I can detach the bike from the front wheel by pulling the handle bar.

I have taken it apart, cleaned and greased it and put together and same thing. I don't know how the suspension bit is fixed to the fork inside the tube? Is this something I can easily fix myself (I've been to various bikeshops and they all too busy or don't deal with suspensions) or do I need a new suspension fork which leads to the next question: Could I fix this myself? I'm quite good at fixing things but had a bit of a problem fixing a new chain to my bike and ended up bringing it to a shop.

Thanks in advance for any replies.

if i recall that fork uses the spring to "screw" into the lower, but by the looks of it the forks have seen better days and i would be looking to replace them.

OMG!

Ok, I'm looking at getting this one:

Marzocchi MZ Supercomp 2008 Fork

Is it fairly easy to do and what size do I need? 100 or 120mm?

nicklouse

100 or less. and the MZ is about as bad as your current fork.

try a RS Tora.

dadude456

lol, y omg?

Rockhopper

I've never seen forks do that! Just imagine what would have happened if you'd managed to pull a decent wheelie!
OMG!

that fork is shocking to say the least!! how much rust is in there?!

dadude456

true, could have ended very badly.

@ nicklouse: Do you mean the Rock Shox Tora 302 UT?

Is there anything particular I have to look out for?

Well, I had the bike for about 11 years now and apart from the frame and the fork, I replaced pretty much everything, so I guess it's time for the fork now.

clarkson

yep id say so! also consider the mx comp.

you mean the mx pro? can't find the mx comp.

What's a poploc? Does that mean I have another control on the handle bar giving me the option between rigid and suspension fork?

clarkson

thats what i meant!! poploc, if its the remote version yes, you have the locjkout lever on the handlebar.

Does the current fork have a threaded or threadless steerer?

dadude456

not quite sure, why?

nicklouse

well if it is threaded your fork choice changes unless you also change the headset.

Also the fork steerer "may" be a different size to most forks now.

sweet zombie jesus that's horrible. I dread to think what might happen if you were to ride it in that state. :shock:

I think he meant this Tora 302 100mm , not U-turn, but you have Lockout, Preload and External rebound adjust. U-turn will not suite.

dadude456

This is what I got. How can I find out if it's threaded and if the forksteerer fits?

I also seen that the Rock Shox Tora 302 - fork says "disc only" and as I have V-Brakes this is probably not an option?

supersonic

The fork looks to be a threadless steerer.

Yes, you will need V brake mounts.

xtreem

Well you can buy that Tora from somewhere else, with V-brake mounts, not form Merlin.
About steerer, most forks come now with 1 1/8" steerer diameter. Measure yours to see if they are the same size.
Other cheaper forks with V-mounts, Rock Shox Dart 2 or 3.

About headsets I don't have a clue. Maybe nicklouse will help you.

I assume the tora is this;

dadude456

Thanks for all the replies.

That's as far as I got. I assume it's threadless.


How do I remove the fork from the frame? I put some WD40 on it and tried bashing it with a mallet, it didn't move an iota. I tried twisting the black rings, same thing, didn't move at all.

bash it harder with a soft mallet. I'm not kidding!

Step 1: remove wheel & brakes

Step 2: raise the frame so that the forks aren't on the floor

Step 3: hit with mallet

Step 4: swear as the forks drop out onto your toes

nicklouse

have a good old read of Parktools, linky below.

dadude456

Ok, many thanks. I will try that over the weekend and make pictures of my swollen toes ;-)

I think this one should do. It has the fixtures for the V-Brakes.

RSTora302


@Xtreem: Do you think this wouldn't fit because of the U-turn?

Do I need anything else - before I place my order?[/url]

supersonic

U turn is a good feature, as allows you to dial in the travel of the fork. But:

A: You have to fit it
B: You have to fit it

You need to cut the steerer to length and fit a star nut in iit.

Shyte...that pic (post 2 3 or 4) is gonna give me nightmares :shock:
