Hi M - yes, this will fit that frame perfectly. Thanks, Flipp.


Hi will this fit my koxx levelboss mod? Thanks

Reply from TartyBikes on 06/01/2015

Hi Jacko - this precise model would not fit as it is an Internal headset and your frame requires a Standard. We have the equivalent Standard headsets from the same manufacturer available here: http://www.tartybikes.co.uk/standard_headsets/obp_sealed_headset/c19p12431.html Hope that helps. Thanks, Flipp.


Ok I might be getting a Gu 20" frame soon, would this fit it? Thanks

Reply from TartyBikes on 08/01/2015

Hi Jacko - no, the GU frames use standard headsets too. These headsets only fit headtubes designed for Internal headsets. Thanks, Flipp.


hi, could you please tell me what the O.D of the cups are please? thanks

Posted by toby on 22/06/2015

Reply from TartyBikes on 22/06/2015

Hi Toby - thanks for your question. The O.D. of the part of the cup that sits inside the headtube is 44.0mm, and the widest O.D. of the part that houses the bearing and sits above/below the headtube is 46.5mm. Hope that helps. Thanks, Flipp.
