In most cases in the last year or so - handled two myself...saw shop handle a couple more...Shimano varied in what it sent out. Always a crankset and bottom bracket. Sometimes a front derailleur, sometimes a chain, sometimes a cassette even. - saw one instance with everything. Kinda weird...
...but no complaints from the customers...saw that they were coming out ahead despite el cheapo crankset and just went with the flow. If you think about it - it's almost a bike overhaul/rebuild...
One customer actually suffered a injury - I encouraged him to send all his accident and medical reports to Shimano as Shimano is supposed to record incidences...as well as take in and replace cranksets.
What really amazes me is how more than ten years later - they still show up. THIS WAS A HIGHLY PUBLICIZED RECALL! Each case in the last year - the customer was not even aware of the recall. One was the original owner of the bike...never knew...
So keep an eye out folks...
