matt rushton Posted February 9, 2006 Report Share Posted February 9, 2006 Hi all (this might be completely stupid). But I was thinking today in school could you get a rear hub (profile), and a front freewheel (white industries). On a mod to give your bike better pickup. Has anyone tryed it.

sir trial a lot Posted February 9, 2006 Report Share Posted February 9, 2006 Someone is bound to have tried it but i dont like the idea of it. When you think, sometimes theyd engage together and other times they wouldnt, so it would be unpredictable when it would bite. Quote Link to comment Share on other sites More sharing options...
JT! Posted February 9, 2006 Report Share Posted February 9, 2006 The engagement would actualy be alot worse in theroy. Becuase when you pedal kicked, one freewheel would need to engage, and when that had engaged, the other one would engage.One over ACS ep's + One over Profile ep's (multiplied by the gear ratio for the 'real feel' ep's) = One over overall ep. 1/36 + (1/48)*1.5 = 1/x0.0278 + 0.03125 = 1/x0.06 = 1/xx = 16.66So the engagement would feel about 17ep. But, the freewheel at the front won't actually turn, becuase the profile would be the one that turned, because it has little resistence so the chain won't move. So actuly all what i did up there is BS. And the front freewheel will just act as a fixed cog.So the engagement would be the same, you'd have a heavier overall system. But definatly not more EP's.

trials_king_2005 Posted February 9, 2006 Report Share Posted February 9, 2006 i don't think it would work mate my friend tryed it and the gearing was utterly rubbish and they neva engaged together Quote Link to comment Share on other sites More sharing options...

Concussion Posted February 10, 2006 Report Share Posted February 10, 2006 I was thinking this also. Oh well, glad that's resolved, I just couldn't imagine what would happen Quote Link to comment Share on other sites More sharing options...
Danny Kearns Posted February 10, 2006 Report Share Posted February 10, 2006 I can see what you are saying and its a great idea, but ................Is there actually any need when you have a profile because it already has enough engagement.No mate in my opinion it wouldnt work because you would have to lock the rear hub out would'nt you ?Dan !

Ben Geary Posted February 10, 2006 Report Share Posted February 10, 2006 I very much doubt it would work, would be to much trouble really. Quote Link to comment Share on other sites More sharing options...
mini Posted February 10, 2006 Report Share Posted February 10, 2006 Hi all (this might be completely stupid). But I was thinking today in school could you get a rear hub (profile), and a front freewheel (white industries). On a mod to give your bike better pickup. Has anyone tryed it.I have tried that but in my expeiriance using a profile and a fixed 18 tooth sproket on the front is the best. using a good free wheel and a profile is pssibly a bad idea because when i done it my free wheel broke. i hope my advice has helped you mate.
