Does this look like a Simplex styled Rear Mech (Derailleur)?

[CyclingTheLakes]

Okay, first off, I know a lot of people are unsatisfied with the old Prestige Simplex derailleurs but if they were improved and more durable, they might change their mind. I think the Delrin(?) plastic pulley wheels are where the problem was on the old Simplex rear mechs.

Similar, not exact. Or perhaps someone will point out I'm totally wrong, I'm also looking at the next rear mech up dubbed an ATB long cager. http://www.niagaracycle.com/categories/ ... th-bracket as I do run a triple crank, I assume this could work.

So, I figured for "Retro-Bike" fiends, they might find this info useful for Retro-Rides. :xmas-big-grin:

I think if one just saw a bike go by or even parked and one casually walked by, one might think this was a classic Simplex rear derailleur. These may show up on ebay but otherwise, not sure where else it is available.

If I remember correctly, I think the problem with Delrin was on the front derailleur, if the clamp got over tightened it would crack. I've never had a problem with a Super LJ rear, in fact its about the smoothest shifting derailleur I've used.

Velo Orange has waged into this debate, there is a lot on the net:

Simplex has always made good derailleurs, but in the 1960s they made the error of using a new miracle material, derlin plastic. This material was very tough and very flexible. The derailleurs would wear out rapidly, deform under load, and be perceived as cheap. But the basic design was ahead of its time.
