this happened to my friend too. they completely froze and wouldnt move. my advice is to get the fork rebuilt with upgraded compression and oil cartridges
the problem with riding in the 'winter' season is the forks are affected the most, as they have oil, rubber, metal and other stuff and when its cold they react, and if they are air (im assuming) the air can act like an ice cube and physically lock the forks screwing the internals over.
i would go back to the shop where you got the bike from and explain whats happened and they should sort it out
mine do that too, they only like 1 week old, at the start of the day when i get it out of garage they super bouncy but as the day goes on and it gets cold they end up almost fully rigid, hopefully in the summer they will be better tho
wut year is the fork if its an 08 or 09 it was bound to break sometime switch to rockshox before it become a big problem
08, i want to get argyles but its a cost problem as im only 15 and its alot of money for a 15 year old to get, i have a saturday job but it still wud take long to save up..
My rockshox did that but that was because i let someone ride my bike and they dicked with the lockout, knowing this and that the DJ3s dont have this option, and since it wasn't that cold out i'm guessing it has something to do with the compression circuit. Best bet is to take it to the shop where you got ur bike, HONESTLY explain what happened and see what they can do, dont try to mess with it your self seeing as how the shop will not be nearly as likely to A)help you out due to liabilty B)and if they do help and do the service its gonna cost an arm and a leg where as they may have been more apt to help cheaper or free for fork failure. Guys at my local bike shop pretty much stopped selling Marzocchi forks other than the 888 and other high travel forks due to the DJ1,2,3's all having similar problems constantly.
My dj1s did this I had a faulty rebound cartridge. take it back to the shop and get them to check it.
dj3s dont have rebound, id suggest asking them for 2009 internals, thats what they gave me for my dj1 seizing, off warranty and it should be problem solved. im surprised since the dj3 internals are very simple
