I sent them to my brother in N Ireland, thats why I did a big order, he sent them to me for a few pounds. Their shipping was ridiculous if I remember right.
A couple of mates got some of them too, didn't get any feedback from them.
Ive been buying sets of Shimano pads from Bike24 (non finned) for 5 euros a pop, they fit my roadie, 4 of my MTB's and both my boys bikes. Do the fins on shimano pads do much for regular trail riding ??? Would maybe buy them if I was riding DH or had a trip planned to do the 21 Tour de France climbs/descents, but 5 euro sets of organic GENUINE Shimano pads are going great.
