fork replacement
 

I have a 1 inch threaded fork on my bike can I change this to a threadless carbon fork

Yes. You will need a new headset and stem along with the fork.

Kestrel makes a 1" carbon fork (the EMS Pro) with a steel steerer that is both strong and stable if not particularly light. Reynolds and Easton make a 1" all carbon fork and Performance offers a house brand 1" carbon fork with an Al steerer.

The only problem with 1" all-carbon forks is that you are limited to about 25 mm of spacers under the stem and that limits how high you can get your bars.

Thanks it seems doable and may make the bike more enjoyable

Nashbar sells a 1" carbon fork with aluminum steerer for only $60, plus they have a 1" threadless headset for $13 :)

Thanks I think I will give it a try
