Well the cranks started flexing something shocking, and the arms were fine, pedals were fine, bb was fine only thing it could have been really. But if you say it wasn't I'll take your word for it mr "I know all about trials". (Y) (Y)
And the fact the cranks lasted over a year with me on them really impresses me, a set of gayativs lasted me one month on the trials bike, and I killed 3 in 3 months on me jump bike, twisted arms on one set, and f**ked the inserts, inserts actually came out of one of em and the 3rd set started flexing really badly. (Y)
I say they are the best cranks I've ever ridden, go get some you will not be dissapointed in the least. (Y)
