Steerer Tubing
Hi,
I'm thinking about customizing my bike and I'd like to extend the fork a lot. I figured I could do this by making the steerer tube longer. Is there somewhere I can order some steerer tubing with the correct threads and a coupler to join them? Or, is there some place locally like a machine shop that would do this for me? Places like Home Depo sell 1" pipe and they thread if for you but it's the wrong thread count and they only have one die. I need 26 or 28 threads per inch. Also, I've tried looking for a really long fork on the net but couldn't find any. Who on the net sells extra long forks? Thanks John |

The joined steerer would likely fail, causing you to lose control. Instead, look for a high-rise threaded cruiser stem, sold by Pyramid bicycle products, carried by J&B distributors at your local bike shop. Also, local bike shops should have adjustable stems with which you could angle it way up and get your handlebars high. To answer your last question, there is an Alpha Q-carbon fork with a really long steerer, but it's carbon/threadless and likely unsuitable for your bike, unless you're willing to change headsets. You need to add more details like what kind of bike, what wheel size it takes, and what it is you're trying to accomplish. I don't mean to sound condescending, but if you don't know what you're doing, you may very well injure or kill yourself with your from-the-hip layman engineering. -- Phil, Squid-in-Training |

Threading a steerer extension together isn't going to hold together if you're trying to do a chopper thing. You'll run into all sorts of issues with mounting the headset bearings as well. Mostly you'll need to weld or braze or have a buddy who can. Ron |

So I guess you wouldn't recommend cutting off a fork on an old bike and sliding them over the dropouts on my bike and bolting them on like I have now? Yes, I'm trying to do the chopper thing. I didn't want this to be a discussion about the problems with the rake angle, trail and seating the bottom crown race that are associated with extending the fork. I already have highrise handlebars but I want a longer fork. Thanks guys for your help. John |

The drift of your questions suggests that you aren't ready to take on any of the methods I have used, which involve silver brazing and lathe turning. If making a rough-and-ready chopper bike is your goal, and you are content to do a bit of trial and error, then these pages may be of some use to you: http://dclxvi.org/chunk/tech/fork/index.html http://www.fortunecity.com/olympia/cobb/117/cpcp1.htm http://scul.org/SCUL/Fleet/Construct...struction.html Chalo Colina |

That's probably safer than the threaded on steerer tube extension you were asking about. Yes, I'm trying to do the chopper thing.

A friend of mine created a chopper using three forks, end-to-end, welded together. Check it out in action he http://plaza.ufl.edu/phillee/cbr/chopper.jpg -- Phil, Squid-in-Training |
