Lifting Handlebars

[cyclingfiend]

Hi. I have just ungone surgery in my neck - vertebrae fusion - and the doc says that I should raise my handlebars about 2cm to avoid continually lifting my head excessively. I investigated this and see that the forks and bearing part - a carbon fibre tube - are all one piece and have been cut to length. Is it possible in any way to extend this tube part - like join another short piece - so that a spacer can be inserted below the stem, or do I have to buy new forks?

New forks but you can get a stem that sits more vertical and then put on riser bars.

just buy a stem that rises. doh
