1" threaded to 1" ahead conversion

I've been offered, at a very good price, the chance to upgrade my standard 1" threaded steel fork, to a 1" non-threaded carbon fork, complete with ahead set stem. Personally, i feel this would be a worthwhile upgrade.
Could anyone give me any help with this? Would i need a new headset? Is this conversion possible & worthwhile?

Yes, it can be done as long as the steerer tube on the fork is long enough. for your frame and the headset and stem which you plan to use. Spacers can be added above and below the stem if it too long or it can be cut down. Yes, it will require a threadless headset as well as the new stem and fork (plus any labour costs).

Assuming you like the idea of reducing the weight and as long as you are able to replicate your current riding position (assuming you want to) and you can do it for a reasonable price it is probably worthwhile. One thing I wonder: Is the fork new or used? I'd be concerned about buying a used carbon fork if I didn't know it's history as a fork failure is definitely something to be avoided. Also, if the stem that is part of this 'deal' negatively affects your riding position you will have to buy another one as there is no height adjustability with threadless (unlike threaded). You might want to factor that into the cost.

bikerider,

Thanks for your reply. Unfortunately, i don't know the history of this fork. I need to check some measurements out before making a final decision, relating to ride position etc.

How complex would the removal & replacement of the headsets be?
Any help or suggestions would be appreciated.

To get an idea of what's involved, check some of the links on Park's page:

http://www.parktool.com/repair_help/....shtml#headset

It's not extremely difficult but it is one of the more involved operations and it requires a few special tools in theory.

This site describes how to do it with more commonplace tools:

Another issue is the proper reinforcement of carbon steer tubes. Does this fork have a carbon steer tube?

Incidentally, what length of stem extension do you use presently?

Thanks for your suggestions & guidance, guys.

I actually decided not to upgrade on this occasion; i felt the steerer tube had been cut too short, and this would have negatively affected my riding position, combined with a shorter than present stem length.

Anyway, thanks again - it's been a good intro. to these forums.
