Yup they’re split olives and if you’re careful with a Stanley blade you’ll be able to slice out the barb too - did this with my first one when I dropped a barb and couldn’t locate it...
RX discs now fitted. 😍
Treated myself to some matching bar plugs too.
Ah I've realised hope use a split olive and the insert might be re-usable.
Buying new hoses and fittings is making it look less economical for me.
I need post mount front and rear I'm afraid - I would have quite fancied the purple tho. Send me a pm if you have a price in mind!
