I have an older 26" Pacific Dune mtn bike that the threaded portion of the stem on the fork sheared off. What do I need to know and how do I get the info to find a new fork that will work? My LBS didn't have any used forks that will work. I just want to get a decent basic fork for dirt cheap, color can be changed.

have you try pacific and see about a replacement fork ?

most likely would be cheaper to buy a new bike.

Try Niagara Cycle Works. They have some really cheap MTB forks that should do the trick.

Here's an example: https://www.niagaracycle.com/product_...ducts_id=10825

I am buying a new bike, but hate to see the old one go the way of the scrap heap. Even the LBS said it pretty much was in mint condition. If I can get a fork for dirt cheap, I'll fix it myself. but Im not sinking more than $20-30 into it. the bike shop said they could sell me a used fork for $10, IF they had one that would fit, in which they dont.

Mint or not, the quality of the frame isn't any better than the broken fork. Scrap it.

entertain me, how do I find out what size of fork I need?

Did you look at the Niagara Cycle Works link I posted? You can get a fork there for a little over $20, likely less than $30 even with shipping.

You need to know the length and diameter (likely 1" in this case) of your steerer tube in order to get the right size. I'm assuming this is a 26" wheeled bike. You can get away with a longer tube length but you'll need to cut away a portion of the tube and possibly have it the tube threaded down further (an LBS job). The right length makes your life much easier.

yes I did and thanx, but like I said I didnt know what size I needed....until you just answered it. thanx.

BTW, Im not scraping the bike since its still in good condition. If I can replace the fork & bearings for dirt cheap, I'll keep it as a back up or to use to go fishing with so I don't screw up my new bike.
