Jefferson C from Bikeguide modified his Taska hub quite uniquely. Unfortunately it has not been tested yet. However, I felt it was important to just show the modifications made.
Well, Here she is:
This coaster is both, LHD and 9t driver.
- I first started off with a coaster brake hub. Removing the brake pads, and machining down the bearing cone, so now it is just large enough for the bearing to run on.
- I then took TWO clutches, cut them to a specific size, then welded them in the middle. Also before I welded them, I had pressed in a washer in the middle, for the spring ( that you can see in the pics ) to rest against.
- Now, having an extra long clutch, allows the hub to work LHD, it presses the clutch outwards, towards the opposite side, to make contact with the hub shell.
- The spring that you see, helps the coaster disengage with little, to NO back pedal. You can essentially pedal, not move the cranks, and hop into fakie, without it locking up.
- The drag system, which you can’t see, is just hidden inside the clutch. All it is, is a hose clamp, with the tabs on the end. The taps grip the inner threads of the clutch, while the clamping force against the smooth part of the axle, creates drag.
- Lastly, for the 9t driver. I basically used the stock drivers from a coaster brake hub, but cut off the piece where the stock cogs slid over, leaving only the threads, ( that thread into the clutch ). I then used a Primo Mix 9t cog, and some solid steel, to weld it together. And lastly welded a bearing cup on the end, to accept the driver bearing.
Downside, its fairly heavy. Who knows if its real reliable. And the driver has distorted pretty bad from all the welding. I may just buy a Nankai 9t driver and just use that.
This was the first run at it (it has obviously changed since then):
