I use ones like this on one of my bikes and really don't notice any difference from the more expensive ones. They are much better than 105 blocks in the wet. If you're in London I can let you have 2 pairs for free if you want. https://www.amazon.co.uk/Pairs-Brake-Installation-Caliper-Blocks/dp/B0714C6CXW/ref=sr_1_40?keywords=Bike+Brake+Blocks&qid=1669062594&sr=8-40
