Rocky Mountain Bicycles has just recalled at least 78,300 mountain bikes due to a quick release safety issue. This is the same safety issue that caused a recall of 1.5 million bikes last year, however, Rocky Mountain was not included in that initial recall.

The current recall affects 17,300 mountain bikes sold in the United States, and 61,000 mountain bikes sold in Canada, according to cpsc.gov. However, SportsOneSource.com reports that 130,000 mountain bikes in total have been recalled. While we haven’t been able to substantiate that number and have found it in no other sources, it’s possible that figure includes bikes sold outside of North America.

According to the press release,

This recall involves all 2003 through 2016 models of Rocky Mountain bicycles equipped with front disc brakes and a black or silver quick-release (QR) lever on the front wheel hub. Bicycles that do not have disc brakes are not included in this recall. When the front QR is fully opened, if there is less than 6 mm — or the width of a #2 pencil — between the QR and disk brake rotor on the wheel, the bicycle is included in this recall.
