I know , but it's the maximum they can get ,
cutting a cm of each side of the handlebar would do the trick , but I like the handlebar like it's now ... , so that's no option either

a longer cable would completely do the trick , but haven't found a company yet to do it ...,

I have the broken cable as a reference now , so maybe I can take this to somebody so they can have a look at making just one like it but let's say 10 cm longer
