Houseface Posted February 4, 2007 Report Share Posted February 4, 2007 the only way your going to get it in there is by filing out your dropout to 14mm otherwise it wont work.steve. Quote Link to comment Share on other sites More sharing options...

newb Posted February 4, 2007 Author Report Share Posted February 4, 2007 Its a proper cassete hub with 13 tooth freewheel (proper is the make by the way sorry if you already no) Quote Link to comment Share on other sites More sharing options...

CurtisRider Posted February 4, 2007 Report Share Posted February 4, 2007 Its a proper cassete hub with 13 tooth freewheel (proper is the make by the way sorry if you already no)well, its gotta be either a cassette hub or a fixed hub to take a freewheel....so by 13t freewheel do you mean sprocket?the only way i can think of is by grinding the axle flat on both sides, so thats its 10mm thick, this means you can still use the boltslook at an old sturmey archer hub to get what i mean! i shall try and find my camera so i can get a pic for you of one, cos i got an old dyno sitting in my room Quote Link to comment Share on other sites More sharing options...
newb Posted February 4, 2007 Author Report Share Posted February 4, 2007 (edited) i was thinking of doing this but didnt no if it was a good idea !pics would be great also would the axel be strong enough if i filed it down ?

Onza Kieron Posted February 4, 2007 Report Share Posted February 4, 2007 Im likely to get corrected by some gay BMX nberd but the main reasons BMX's have 14mm dropouts is for pegs. I think if you carefully and slowy (so not a great deal of heat is put upon the axle) grinded the axle flat then ran a tapping Die down the axle you would be fine, BUT make sure you get the flat bits on each side in EXACTLY the same rotation on the axle or else your well screwed..

Dan6061 Posted February 4, 2007 Report Share Posted February 4, 2007 Can you not get 'female' axels on the Proper hubs? - Like on Profiles?Basically, it's a hollow, threaded axle, which is still 14mm thick, but with a M10 thread, for 10mm bolts.If you can fine one of them, i'd advise you get that, and simply convert the axle, instead of having to grind away at anything.

newb Posted February 4, 2007 Author Report Share Posted February 4, 2007 ok i will have a look Quote Link to comment Share on other sites More sharing options...
ogre Posted February 4, 2007 Report Share Posted February 4, 2007 before you do this i'd make sure the hub you use isn't gunna skip like a bitch (little kicks compared to a more fluid pedaling action in bmx) if that makes sense? (remember some guy who rides bmx trying pedal hops+his hub skipped like a schoolgirl) would be mega shit if you did all of that + then found yourself flying over the bars all the time Quote Link to comment Share on other sites More sharing options...
guineasmithpig Posted February 4, 2007 Report Share Posted February 4, 2007 or strip the axle out of the hub and get an engineering firm to make an exact replica, but with necessary adjustments to each end of the axle. then you can use the original bearings and such (making spares readily available). i'd strongly advise against bodging each end with a grinder! if the flats aren't added accurately, then you will most likely end up putting uneven stresses through your frame and hub, leading to premature deterioration! also, the female axle jobby sounds good. i'd get a quote on having an axle made, and see how that compares to converting to the female axle cost wise.smithy Quote Link to comment Share on other sites More sharing options...

ogre Posted February 4, 2007 Report Share Posted February 4, 2007 what hub/freewheel are you running atm? why not replace freewheel/service it/etc(hub conversion seems a bit pointless to me) Quote Link to comment Share on other sites More sharing options...
