Subject: Re: [CR] Interesting Article on Pedal Failure

As the spindle was case hardened it implies a very inexpensive pedal. My expedience with period Campagnolo pedals (which use very good design, materials, and manufacturing) have given me faultless service. This type failure does happen, but is rare. Now days reputable bike makers use only pedals that meet at least JIS standards, even for low end bike models. One problem though is most higher price bikes come without pedals, leaving the choice to the customer. In this case the mike maker has no control over the quality of pedals used.
