Title: How smart is this fork?
Post by: shovelon on March 31, 2008, 04:04:45 pm
I am kind of interested in this fork. But how smart IS it? http://cgi.ebay.com/K2-SMART-FORK-for-mountain-bike_W0QQitemZ200212546457QQihZ010QQcategoryZ36135QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

hmmmmm...............about as smart as an earthworm?

sorry, must not diss the almighty Girvin........................

I have NR-5 Smartshocks on my Crosslinks and to be honest I can't tell when they're switched on or not...................

Go for it at a good price and it'll be interesting..............!

Not a bad fork according to the reviews back in the day, but there are lots better things available these days. The electronic component of those forks was notoriously short-lived, at which point it just becomes a "regular" fork with dead weight inside and only so-so damping. I wouldn't waste my time with any suspension from Girvin or Noleen (gasp!).

Stone the heretic!.......................


Yes, I'm coming around to this POV.

(Maverick fork and Manitou Swinger shock waiting to be installed)

I am going to have to pass on it then. The valving is indeed bass-ackwards.

The only reason to buy one of these is if you wanted to keep an older K2 orginal. Something to think about if you want a true retro bike. Personally, I like mixing the old with the new. That's why my next project is to put a swinger air shock on my 856's crosslink. I just have to design and machine an adaptor to compensate for the difference in eye to eye length and to provide a little clearance for the air valves.

You may get a little more travel too.
Andrew(Frankd3000) adapted a cane creek to his crosslink. Although better, not sure if he was happy with it.

I am really into the Mega-air VTO forks. Thought the smartfork would be similar, but I reckon not, because the valving is all wrong, and is coil sprung I think.

Right now I'm more worried about too much travel. I have a 200 mm shock in the drawer right now and am planning on using it. I've looked at Andrews (FrankD3000) setup and he used a much shorter shock with a long adaptor. I think you are correct about him not liking the fork. If you look at his gallery (the old one), he switched to a Manitou fork three months later.  I am looking at making adapters similar to jazclrints design where he installed a Fox Talas 200mm shock on the front of his crosslink. http://www.flickr.com/gp/16675643@N08/5HG0QK  He had a short discussion thread about this back in October last year. Unlike Andrew, I think he has been riding this Fox shock set up for a while. Great minds must think alike. I have two Noleen Mega Airs. One on my Haro FS and one on my son's bike. Great performing fork with a stupid simple design and easy maintenance. It'll be a sad day when they finally wear out.

That is my old fork!!  Crazy, I sold to him in Nov. and he's already parting with it.

So how did you like it?

works fine, plush for sure, a little heavy, but in great shape when it left my hands...but I've always been partial to the Girvin / Noleen linkage so my opinion is probably biased

Actually It's not a Talas, It's a Float RL, but I don't know if there's a difference.  I talked extencively about it a few years back.  All the stuff is in the archives.  I have lost the drawings I made and with school I have not had the time to recreate them.  My machinist is willing to make a new set for anyone that wants one.  I am still refining the design, but I love it.  The only issue is not the length, but the dampening is a little too much.

Great minds, definately.
