Captain Scarlet Posted February 17, 2009 Report Share Posted February 17, 2009 I'm sure most of your know the term "freewheel float", which on a front freewheel, becomes apparent when you spin your cranks backwards and you can see a side to side wobble to the freewheel (or float in this case). My first question; what actually causes freewheel float?, I understand the workings and internals of the freewheel, but have never known as to why most freewheels have float to them.Secondly with my freewheel, the side to side motion is apparent, I also have an incredibly noticeable up and down movement to my chain when the freewheel is not engaged (in freewheeling state).I've had this problem for sometime, and dismissed it as chain stretch, but its getting ridiculous now, especially when getting chain tension.I shall be replacing my chain soon (and rear cog just to eliminate the possibility of very quick chain wear), but if this does not cure the problem is there anything else that can be done..?Also, the freewheel is a Try-All one and the lockring doesn't appear to be loose, so I can't dismiss it as the actual cog moving from side to side.

N.Wood Posted February 17, 2009 Report Share Posted February 17, 2009 I've always thought its to do with the threads on the crank not being 100% square to the arm, giving it a side to aide and maybe up and down wobble. Quote Link to comment Share on other sites More sharing options...
PaRtZ Posted February 17, 2009 Report Share Posted February 17, 2009 (edited) firstly, its important to note (as I think you already know judging from your intelligent post) Your freewheel is NOT broken. It is as you say, a well known thing (although the terminology is new to me)As Nick's said I've heard its down the how parallel the threads are machined against the crank. Im sure I read somewhere of a crank that was manufactured in a different way so as to reduce/remove freewheel float. But also the freewheel itself has some effect on it too. This bit Im not clear on, maybe onza or another manufacturer can clear this up?Some freewheels float alot, I've seen monty freewheel's boogie-ing like mad whereas ENO's tend to be a bit more tame:$ Edited February 17, 2009 by PaRtZ Quote Link to comment Share on other sites More sharing options...

Alex Dark Posted February 17, 2009 Report Share Posted February 17, 2009 basically due to how accurately the threads are machined...in general a higher end freewheel will have less "float" than say a cheap dicta. Quote Link to comment Share on other sites More sharing options...
NVWOCI WVS Posted February 17, 2009 Report Share Posted February 17, 2009 also the threads on the cranks will make a big difference. They arent always bang-on. Quote Link to comment Share on other sites More sharing options...
Jamie_Trials Posted February 17, 2009 Report Share Posted February 17, 2009 Isant it just The bb axle that bends? Quote Link to comment Share on other sites More sharing options...
JonMack Posted February 17, 2009 Report Share Posted February 17, 2009 No, it's the threads on the crank/freewheel. Quote Link to comment Share on other sites More sharing options...
Muel Posted February 17, 2009 Report Share Posted February 17, 2009 You'll have a hard job bending a BB axle, they tend just to snap.It's all down to how accurately the cranks have been machined. I've also found that square taper tends to "float" more than ISIS. Quote Link to comment Share on other sites More sharing options...
