Yeah - it's brilliant as part of the overall bike (https://flyingdutchman.bike/our-bikes/dutch-city-bikes/pilen-lyx-mens/), the only drawback being if you increase your cadence to go up a hill it will shift up without you wanting it to. I like not having shifters on the bars though.
Currently it's with the lovely people at The Flying Dutchman - who I understand have reached a point where the only way they can make it squeak is by having their heaviest employee put his whole weight into the brake. I could replace it, but I have no idea where to get one and they don't have a SRAM dealer.

I was very silly and massively overtightened it.
