Had both of my pedal extenders break yesterday, could have been dangerous had I not been riding slowly.
Anybody heard of these breaking before .

1 broke whilst pedalling ,as I removed the other one with a spanner it just fell on the ground!How both?
Was always a little worried about the design,think I will send them back to supplier and see what they have to say.That design is an accident waiting to happen. The sharp transition from big to small will always break after time. The transition should have been given a small curve/radius. I am surprised they have not had an ambulance chaser lawyer on their case yet.
just got an e mail from specialized.
A question for you engineers!! I have just taken delivery of a pair of pedal extenders from USA. Following the warnings raised by the OP I have contacted the supplier expressing my concerns. They have replied that as the units are milled from "billet steel",they are virtually impossible to.break.
Is there something in what they say, or is it load of humbug.
I am not an engineer so your replies would be appreciated.
Billet is simply a posh engineering word for "nice big chunk of metal". Theyre usually extruded or cast. Basically, they're telling you nothing more than your extenders are carved out of a chunk of metal.
@HertzvanRental
If you can send me the dimensions of the extenders, I can run some stress analysis on different steels.
