Strengths:    travel

Weaknesses:    the preload nob kinda sucks

Bottom Line:   
ok first of all these are a great over all fork. they have enough travel to handle about ant trail and they look pretty cool too. the specs on the j2 says it supposed to have 130mm travel....for some reason mine have 160mm...? but thats a good thing i guess. great forks

Date Reviewed: April 25, 2009

Strengths:    Strong

Weaknesses:    Heavy, makes awful clunking sound when topping-out, preload adjustment is useless, nasty speed wobble when riding hands-free.

Bottom Line:   
At a hefty 5.25lbs, this is Rock Shox sub-entry level fork...and it clearly shows. Your energy will be challenged whenever an obstacle pops up...because your front end certainly will not. And, when you do finally heave your front wheel up- it will be confirmed with a loud click, as the fork stanchions top-out. The preload dial is completely useless, as there is no way to control what this fork does best- top out and bottom out.

Do yourself a huge favor whenever buying a bike spec'd with this front suspension...immediately REPLACE IT, and toss it in the trash. That's right, don't make another rider miserable with it...just scrap it. I weigh 160 and this fork failed to do anything a much lighter rigid fork could.

The nearly six pounds of dead weight is best removed for something that closely resembles functioning. Most bikes can easily be ridden without hands- but with the J2 you will be shocked at how much instability and excessive stiction the fork has and will immediately have you grab the bars...yeah, they are that crappy!

What makes a mountain bike "affordable?" You guessed it...the Rock Shox "Judy2" The first-generation is FAR BETTER than this model. Its a hair just above Wal-Mart quality, and no more. Shame on you, SRAM!!!

Strengths:    Rebound adjustment, lock out, preload adjustment.

Weaknesses:    entry level

Bottom Line:   
This has been a good shock over the last 2 years. I have become a better rider because of it. It allows you to go over just about anything on a normal XC single track. I have taken a 3 foot drop right on to it and it worked great. It is really easy to adjust to your body weight so you can get it just right.

Strengths:    Tough and Sturdy

Weaknesses:    Not very plush

Bottom Line:   
This fork came on my Trek Fuel 70. I didnt think it would be great but it has proved itself. I have put over 1,600 miles on it and still works like new. This fork has taken a beating and has never needed any type of servicing or adjustment. The only reason I stopped using this fork is because I came across a good deal on a Fox Vanilla. I recommend this for anybody who wants a fork you do not have to spend a lot of time maintaining or if you are a beginner. If you are racing you probably want to go with something else.

Strengths:    Good for light people

Weaknesses:    not enough travel and strength for someone 160 pounds or more

Bottom Line:   
These are the worst brand forks ever, i hit a jump 1 1/2 feet high and they exploded and i got all of the internal parts shot at my face. it blew up cuz they made the top cap out of plastic not metal so somthing was going to happen eventually. my injuries were concusion, neck problems, scars on my face almost loss of teeth.

Bottom Line:   
For the money this is a really great fork. I am planning on using it till it wears out completely. I was under the impression that this fork was going to really suck, but I am completely satisfied with it. I have taken it through about anything imaginable and the fork still works as if it were brand new. I will probably upgrade to a better shock when this one wears out, but if you are entry level, this is perfect for you.

Date Reviewed: September 7, 2006

Strengths:    Cheap, trusty, Lockout is very handy

Weaknesses:    not stiff enough, not enough adjustability for my liking

Bottom Line:   
Good fork for someone starting out
... good value, some (albeit limited) adjustability, indestructable.
Lockout works a dream.. only allows 1 or 2 cm travel to dampen slight bumps... good for hill climbing.
Its still working as god as the day i took it out of the shop - ive never done any maintainance on it except for wiping the mud off it.
You will find yourself bottoming it out on bigger stuff.
I dont know how it would go if you were doing lots of jumps, big drops, etc.. i stick to XC
Expect to 'grow out' of them after a year or so
