i just notice that my cab 20mp has a hair line crack at the shaft and grip juntion(it's the "triangle" piece). The outer coating has completely broken and now it makes a wierd popping noise. This is the second or third time that this has happen to me with all of if being cab 20(cab 23, cab 20 tour, cab 20mp).

does anybody know why this is happening?

i know that i don't hit that hard, or abuse my racket, and to me cab series are by far the most durable rackets that i've owned.

Do u have a picture of the crack? let us analyze it.

the crack is very hard to see, but it is visible, it's about 3 to 4 mm long, and it seems like the crack will be getting longer if i con't to play with it.

try to put a layer of super glue or transparent nail polish.

i did that to my last racket but it did not worked, also try fiberglassing it but that to was even a bigger mistake

Since you have problems with ur cabs.. maybe you should send it back to Yonex if there is a warranty.

i think yonex only warrant's the head of a badminton racket all else i am not sure, but i think my racket is a year old, and that any warranty is voided due to the time period that i've own it. but i will try and talk to the shop that sold it to me, and see what they can come up with.
