Threaded forks
#1
Hi I want to buy replacement forks for my Mountain bike, it's a cheap full suspension bike which has threaded forks, its a piece of **** basically lol but I just want to change a few things on it. http://www.argos.co.uk/static/Product/partNumber/3324501.htm


I just wanted to know what precautions do I need to take before I buy replacement forks, I know they need to be threaded as its got a threaded head-set but other than that I haven't got a clue. I don't want to buy expensive forks for them not to fit lol thanks

Your link does provide sufficient information.

Are the current forks 1" or 1 1/8" threaded?
What is the crown race inner diameter?
What is the over all length of the post, and the threaded length?

Once you have that information, you can identify forks that will fit - though you may have to purchase one that needs to be cut to length.

That will still not guarantee that the forks will not alter the geometry of your bike and make it very uncomfortable/difficult/impossible to ride.

Okay how do I find that information? Does it say whether it's 1 or 1/8 on the forks or do you have to measure them somehow? I have no idea about the overall length of the post and the threaded length, I'm still learning about bikes lol sorry. Thanks for your reply Nigel

You have to measure all of the above items, after you take it apart. Please note that on a " 1-inch " fork that the threaded post is actually 7/8" diameter, and on a " 1 1/8 inch " fork it is 1" diameter. Once you have experience, you can tell just by looking.

The crown race inner diameter is in millimeters; typically 26.4 or 27.0mm I always measure, using calipers.

The lengths are the actual measurement; a ruler or tape measure is precise enough.

Cutting to length - a saw guide for the hack saw if highly desirable, and not expensive. A bench top belt sander or equivalent is the fastest and easiest method to clean up the thread end.

Here are some of my bikes; my current primary rides are the Schwinn World Tourist, SR Sierra Sport and Trek T50.

As you can see, I have learned a great deal from the people here over past few years.

Mostly, I am bicycle commuter. Most days, a co worker and I ride the T50, 8 miles in the morning, slightly different route of 10 miles in the afternoon. With traffic lights, we average a bit over 12 mph, we are cruising in the 15 - 20 mph range. On days when she is not available, I ride either the WT or SR; and one of them generally stays at work.

I have other projects in the works; my focus is on a 1985 Schwinn Cimarron and a 1995 Trek 930; both are rigid MTB that will be turned into commuter/touring bikes. The Cimarron has double butted cr-mo frame and fork. The 930 has a triple butted cr-mo frame and cr-mo fork. Both will get drop bars and brifters.

thank you
The WT is the nicest riding single followed closely by the SR.
All were changed quite a bit from what they were when I got them.
