Threaded Forks

[TechniKal]

How do they work? I need to replace the fork on my wife's road bike in order to make it work with 700c wheels. It's a threaded steerer. On Nashbar, they have cheap threaded road forks in different lengths. Are the lengths standard? If not, how do I know what size to order? Do you cut down a threaded steerer tube to fit the same way you do threadless? Also, what tools do I need to remove/install? I've never had to deal with a threaded setup before....

threaded work like threadless BUT in this case, the headset does the work that the stem does on a threadless.

the headset has two nuts that are threaded to the steerer and that adjusts the headset and holds everything together.

the standards were kinda weird with threaded forks.

you'll have to measure the length of the steerer you've got and the length of the steerer that's threaded.

that's about it. you may also want to get a few threadless spacers (same as a threaded but they have a little "key" (a tab) to line them up and keep them from spinning on the steerer.

if for whatever reason you need to cut down the therads, make sure to thread on one of the nuts firstso that after you cut the steerer, you can make the nut reform the first few threads.

tools? just somethign to remove the race from teh old fork and pound it onto the new one. and then the usual stuff to mount the brake and maybe a new piece of cable and housing if the distance from teh brake to the lever gets too much longer.

to remove the race you can use a flat head and hammer. just have to be gentle. to set the race on though, you'll need to borrow a race setter or get a pipe that's got an inner diameter of 1 1/4".

Thanks Carlos. I'll pull the existing fork this weekend and make the measurments. Threadless seems to be a lot simpler...

no prob.

yeah threadeless is much easier.

the shittiest thing was having to cut a threaded down and then find out that it needed more threads. the Campy tool does this job the best but neither shop had that tool. :(

that's when i would punch out for lunch. hehehhe
