Twin chain/drive setups?
« on: October 25, 2014, 03:36 PM »
Seen this done a few times and just wondering if anyone knows of suitable hub suggestions besides a clem twin. Can i just use any old flip flop with the right freewheel?
At the moment im thinking along the lines of machining a secondary thread on the non drive side of a suzue hub  :D

you would need a left hand drive freewheel. and a flip flop hub wont be any use as when you pedal the left side would just unscrew.

You will need a hub with both left and right hand drive threads.  Which shouldn't be too hard to find these days.

You will also need either a left hand crank arm (with spider etc) or re-thread a right hand crank arm.

What about 2 old school right hand crank arms (square spindle) and 2 right hand pedals  :D

Unless you loctite the thread the left hand pedal will come loose all the time

Problem is that running a right hand crank arm with right thread pedal on the left it will unscrew the pedal.

What you can do is look at tandem crank set ups as the rear rider has both left and right drive crank arms.

Do it properly and either rethread or find a classic left hand drive crank arm.

Or - buy two 43/44 tooth spline drive sprockets and slap em on some Profile or similar cranks. No need for re-threading, but they ain't cheap Clint  :daumenhoch:

Does it have to be old school. Cant remember who but someone makes a hub where you can take the driver out and put it in the other side. Think it is called bi-drive or something. Lots of newer cranks have both arms with a sprocket bolt.
Just a thought
