Avoid this like the plague. There is nothing wrong with it, it is a perfectly good piece of kit but made out of metal for extreme durability is not good. The R8070 levers are plastic / resin. If you cross thread it when inserting, you will wreck the threads on the body of the brake housing (£200 if you can get hold of them ATM). A soft plastic one will get wrecked and leave your expensive brakes unscathed. Fortunately I realised I had a crossed thread before I put a spanner on it. I will however be ordering a plastic funnel shortly as I have a worn master cylinder which requires a new lever.
Hey Richard. Thanks for sharing this. Unless the adapter is cross-threaded AND tightened down with a spanner, or similar tool, then no damage to the brake will result. If there's somebody out there who can strip a set of threads using this adapter with their bare hands then I wouldn't like to shake hands with them! We only ever recommend tightening bleed fittings by hand and never to use tools. There is rarely any need for the use of tools when attaching bleed fittings and it is usually counter-productive to do so as it will simply deform the o-ring resulting in a poor seal. I hope this helps to alleviate any uncertainty.
Works well. Nice to be metal rather than the flimsy shimano plastic ones
This is a great adaptor that is vital for bleeding new di2 ultegra brake systems. 1st class service as always! In fact you could go as far as saying.....epic!!
Never performed a bleed on my breaks before,Easy to follow instructions and overall process went well.
I honestly didn't know what to expect at first as this was my first use of a road bleed kit. I used my shimano mtb kit that I already owned and added this adapter. Great quality. Really great. And for 4 quid. Outstanding. Fitted really well to my GRX levers and to the syringe. Sealed up nicely with no leaks, and didn't feel like it would cross thread.
