Hi Coby - thanks for your question. This bottom bracket would fit your frame, but is uses a unique spline that will only work with Truvativ cranks. If you do not have Truvativ cranks you will need to select a regular ISIS bottom bracket. Hope that helps. Thanks, Flipp.

Is the bb shell 68 or 73 in size

Reply from TartyBikes on 04/09/2015

Hi David - The BB is able to fit either 68mm or 73mm BB shell frames. You simply use the corresponding amount of spacers (which are supplied with the BB itself). Thanks, Mark

Hello! I need a replacement BB for my inspired fourplay pro 2013, would this fit? I haven't replaced any of the parts, so i still have the original cranks. Thank you!

Hi Endre - This would be a direct replacement for that BB, so should work absolutely fine. Thanks, Mark


Hello! Which tools do i need to remove one of these and to install a new one? Thanks :)

Reply from TartyBikes on 07/04/2016

Hi John - To remove the BB itself, you'd need something like the IceToolz M091 External BB Tool (Quick find code: 012235). Thanks, Mark

Hi, would this BB fit a 2012 Inspired Fourplay Pro?

Posted by David Gibson on 25/11/2017

Reply from TartyBikes on 27/11/2017

Hi David - If you've got the standard Truvativ cranks fitted to the Fourplay Pro, this BB should fit fine. Thanks, Mark

Adam McGuire

Is this compatible with the TMS Combo V4 frame ?

Posted by Adam McGuire on 08/09/2016

Reply from TartyBikes on 08/09/2016

Hi Adam - We don't have any info about the TMS frames, but I believe they use similar dimensions to the Inspired frames so this BB should fit fine. Please note you would need to use Truvativ crank arms with this BB. Thanks, Mark
