Will this fit on a 2013 intense tracers 27.5

Asked by: Indiomithos
So long as your bike uses the SM-BB70 that appears to have come stock on that particular model, then this is exactly what you need.

Will this fit a Specialized FSR XC 2006 which currently has either the UN-25, 113mm spindle, 68mm English BB or the BB-ES30 118mm, 68mm English.

Asked by: Stav
The XT SM-BB70 Bottom Bracket will unfortunately not work with your Specialized FSR XC. The bottom bracket currently on your bike has the spindle attached. The BB70 does not have the attached spindle and would require a crankset with an attached spindle.
