Hey fedi-bikers!

I need help finding good hydraulic disc brakes with flat-mount calipers for my Specialized Sirrus 3.0.

It came with Tektro HD-R280 front- and rear flat-mount calipers, but I'm not quite satisfied with the stopping efficiency. I'm used to a lot more from years of riding my previous MTB which featured Shimano post-mount calipers.

The guy at the local bike shop explained to me that the factory Tektros were actually quite mediocre calipers, so I weren't to expect anything near to approximating the stopping power of my MTB's Shimanos.

So far I've identified these flat-mount Shimano models:

• Shimano SLX BR-M7110
• Shimano XT BR-M8110
• Shimano XTR BR-M9110

... but most sites that have them in stock offer just the calipers, and I need the whole front-, or rear- or both sets, including calipers, pads, levers, hoses, adapters (if needed), because if I purchased just the calipers, they most probably wouldn't be compatible with what came with the factory equipped Sirrus 3.0.

I'd be grateful for any suggestions, and links to online shops (Europe-shipping preferably) where I can order the whole set from.

Thanks!
