I've got a Hope Bleed kit with the pressurised bottle - had it around 9 or 10 years. Not been used the last 8 due to not running the Hope brakes with the top cap that came with the unit.
Anyway, I stumbled a cross a picture of a later kit and it did have the top cap for the Tech Lever.
Quick email to Hope asking for the part number and price so I could order it from my LBS (sent around 22:30) and by 08:45 next morning, had a reply back asking for my postal address and they'd send one out to me FOC as it wasn't available on it's own.
With any luck it arrives today. Well impressed...not a huge thing but wasn't expecting it. I'm now going to see if I can get a syringe hooked up to it so I can make bleeding even easier (syringe at bottom and top then just depress the plunger of one then the other...makes sure all the air is out and the levels are all topped off...and should be a 2 minute job!).
