bee_ Posted January 16, 2006 Report Share Posted January 16, 2006 you'd probably lose engagement points as both freewheels would need to be engaged (I think) Quote Link to comment Share on other sites More sharing options...
new_to_trials Posted January 16, 2006 Author Report Share Posted January 16, 2006 you'd probably lose engagement points as both freewheels would need to be engaged (I think)Do not understand that why can you not run to freewheel one up front and one on a fix rear hub that all i need to no thanks for the help anyway sam Quote Link to comment Share on other sites More sharing options...
bee_ Posted January 16, 2006 Report Share Posted January 16, 2006 (edited) You could if you wanted too, but it wouldn't be a good idea. How many teeth does each freewheel have? Edited January 16, 2006 by bee_ Quote Link to comment Share on other sites More sharing options...

adamtrials Posted January 16, 2006 Report Share Posted January 16, 2006 Twice as many freewheels to break, twice the chance of you getting injured. Quote Link to comment Share on other sites More sharing options...

bee_ Posted January 16, 2006 Report Share Posted January 16, 2006 (edited) 18:18 ratio, you would need to pedal about 500 times to move an inch It's a bad idea and there isn't a single advantage, only disadvantages.Greater chance of it skipping aswell.

PaRtZ Posted January 16, 2006 Report Share Posted January 16, 2006 For a start you would still have to pedal backwards when fakie-ing, otherwise it wont engage when you pedal kick forwardSecondly the only benefir it would have is your chain would only move + wear when you pedalled. Freewheelling and pedalling backwards would allow the chain to not move at all.The DrawbacksIt would be very rare that your freewheels would engage at the same time, meaning you will have the feeling of only one freewheel at a time. Crap feelingAs said above, move chance of things going wrongMore cost to replace + serviceFrom the sounds of things, 18t freewheels, front and back = 1:1 ratio. Not right at all lol you what 18:12 ratio Quote Link to comment Share on other sites More sharing options...
bee_ Posted January 16, 2006 Report Share Posted January 16, 2006 It would probably sound awesome when freewheeling click! Quote Link to comment Share on other sites More sharing options...

poopipe Posted January 16, 2006 Report Share Posted January 16, 2006 (edited) It wouldn't let you pedal backwards unless you ran a left-handed freewheel - which you wouldn't be able to put on.you'd just end up with extra weight, more chance of bits failing and unless you were very lucky you'd probably end up with uneven engagements - which'd confuse the shit out of me.if you change anything, run a fixed cog up front and a freewheel on the back, that will at least increase your engagements over running FFW. If you do that you'll need to run a 27 tooth cog on the front to get the 'correct' gearing. If you want improvements in the drivetrain just buy an eno.

wayn3 Posted January 16, 2006 Report Share Posted January 16, 2006 (edited) you'd probably lose engagement points as both freewheels would need to be engaged (I think)Yeah you do. Oh, and it doesn't mean you can ride backwards either. And a 18 to 18 ratio is stupid, you wont 18 to 12 or 16 to 12.

monkey gav Posted January 16, 2006 Report Share Posted January 16, 2006 i don't think you can do it the front free wheel setup has the chain rotating while you free wheelthe rear freewheel has the chain stationary while you freewheel so both forces are pulling against each other surely this means that you would'nt go anywhere Quote Link to comment Share on other sites More sharing options...

The downside being that you wouldn't be able to get up anything cos your gearing would be too slack... Quote Link to comment Share on other sites More sharing options...
