Does anyone know were I can get different sizes of the guide that sits on the bottom bracket, the type I need also has a tube to feed the front cable through the frame.

I need one that comes further forward or lifts the cable higher to stop it cutting into the frame.

Would any of these do the job?

You beat me to it.

Thanks but no, the one I need has a long tube to direct the cable through the frame.

maybe this one ?

Yep, it looks like that but whether that particular version would fit my bike or be any better than the one thats on there now i can’t tell.

I have sent an email to the manufacturer see if i get any joy from them.
