After piercing the right diaphragm by abruptly spreading the pads on my cyclo-cross bike, I was able to easily replace it with this part. No need to change the entire lever, it saved me a big expense. Very practical and perfectly compatible! (Translated review)

hard-to-find part nearby thanks to "bike material" I found this part at a lower cost and fixed it myself. Nice savings! (Translated review)
