|can U thread a threadless steel fork steerer?||johan burnt eels|

|was looking for a new steel fork and quite liked the look and shape of the gios especially as it would be easy to remove the decals/paint but excel only has threadless steerer's and from my inquiry the sales assistant indicated that they wouldn't special order a threaded one and that cutting a thread on the steerer wouldn't be advised "as the threads would be too brittle due to the metal" ??????
upon looking at the gios website both the threaded and unthreaded forks are the same weight - i am fairly sure its the same fork with one cut to size and threaded and the other left long and unthreaded.
till now i have never had to question the logic of any excel staff as they have always been aware and knowledgeable but i am not understanding something.
i really cant understand why. especially as the steerer is not chrome plated and pretty much raw steel. i doubt that the steerer is too thin to cut threads into and still retain strength. am i wrong?
im sure i can find a lbs in my area with the old know how and materials to do the job. or are threads cut with steel whilst heated - not to my knowledge.
i still like and have a reasonable investment in quill stem setups and prefer it.

|IT could be done assuming the steerer had enough material to not be weakened. A frame builder or machine shop would be a better bet to do the work. LBS typically can chase threads, but cutting them requires more sophisticated equipment. I had extra threads cut on a fork by LBS and the end result was literally a ruined fork and work that looked like it had been done by a chimp with a broken file.Cannot understand why excel will not order one if you pay up front,and they are available.|

|i would say that they are probably looking to sell what they have as they have not been selling as well as they had probably hoped.
a special one off order would probably cost so much that they would prefer not to quote a price on it.
out of interest what sort of fork did you have extra threads cut into? steel or alloy steer?
i know of an excellent machine shop in my 'hood that will probably do a good job but i will have to see how much it will cost. the forks im looking to replace have started to lose the chrome plating and have seen better days. re-chroming them would probably not be worth it. i haven't seen any new chrome steel forks on ebay and thought the gios would make a good choice.

|The threads that turned out bad on my fork were cut into steel steerer.Probably a combination of improper tools for the job and a moron using them. Happens alot. There are lots of people upgrading good chrome forks to carbon fiber. Try running a want to buy ad in the classifieds here or in the recreation bicycle newsgroup marketplace.A custom builder like www.steelmancycles.com or www.anvilbikes.com can probably build one for about $150. don't know about chrome though. I bought a nice OLMO chrome fork in new condition from the classifieds for $50. People have this stuff lying around and want to move it.|

|Dpends upon how the threading is done. Cut threads are inferior to rolled threads, but I'm not sure which they use. A good LBS has the die to cut threads, but not many like to do it. It's much easier to extend some threads down the steerer than it is to start from scratch - as in your case. If the steerer is heat treated then, yes, you really do have a problem, but then steerers are easily cut with a hacksaw. This all assumes that the wall thickness and diameter of the steerer is the same between the two forks - nothing says it has to be. I could easily see the threaded steerer being a smaller diameter. You could have a real problem trying to thread the larger diameter of the unthreaded steerer or you may find that your quill stem does not fit. It could also be that they simply take threadless steerers and thread some of them, but the Excel folks don't want to take on the liability of telling you it's OK, only to have you experience a failure and then try and sue them. I'd just order the exact one that you want, but if this is too expensive you might give it a try. I'm assuming you've cut threads on something like galvi pipe and know what you're in for.|
|im open to other new steel forks but cant find any||johan burnt eels|

|well, nashbar has some but i dont think it will look like much for their $30 asking.
i like chrome and the rest of the frame is steel with chrome highlights.
im still waiting for word from gios direct. i dont see the need for buying used unless i have no option. as i live in new york there aren't too many cheap chrome platers that i see around here and besides i think my old fork is due for retirement anyway.
i have found some new forks but with touring eyelets and brake mounts. as its a very pretty old race frame it would look a bit odd.
is that it for steel - carbon or nothing?

|Any half-decent LBS would have the diecutter. Shafts are the same OD.|
