Szymon Posted June 27, 2023 Report Share Posted June 27, 2023 Has anyone tried drilling and threading holes in a truvativ crank (GXP,Howitzer)? I mean DH or 1.1 cranks without holes for a small sprocket? Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted June 27, 2023 Report Share Posted June 27, 2023 Definitely could be done. Probably would only use them with a chain tensioner, so it will take out any slack if the ring isn't perfectly concentric. Quote Link to comment Share on other sites More sharing options...

I changed it for something more use-intended afterwards. Quote Link to comment Share on other sites More sharing options...
MaderaMark Posted June 28, 2023 Report Share Posted June 28, 2023 I tried it with Hussefelt cranks, ended up only 2 holes made. So hard for home tools and incorrect drill bits, doable but needs good preparation. Quote Link to comment Share on other sites More sharing options...
