Subject: Lightning Thunderbolt with internal hub?
|
Hi Folks - I have a Lightning Thunderbolt from back in '99, when they were
still making them. I've noticed lately that the shifting on the front 3
chainrings is pretty rough, not that it was ever great with the cheap
components that it came with. And I got to thinking, if I'm going to
upgrade components, why not just get a 3-speed internal hub like a Sachs
3x7 (if they still sell those) and have it put on the front instead of the
chainrings?
Has anyone ever tried this? Does anyone know if it would be a good idea?
I'd like to get some input from knowledgable folks before I do anything
that could mess up my bike.

Why remove the front Derraileur? It would just give you even more of a gear
range combined with the 3x7. (I used to have this type of setup on my trike)

I'm not sure what you're asking for. A SRAM DualDrive (aka Sachs
3x7/8/9) hub mounts in the rear. The "3" refers to planetary gears
operating inside the rear hub. They're still available:
http://www.sheldonbrown.com/harris/sram.html (scroll down a bit), but
they don't "replace" the front chainrings or shifting mechanism in any
particular way. You could put one on your bike, but then you'd have a
63 (or 72, or 81) speed bike. You could install one and eliminate all
but one chainring, but that's still not "putting an internal hub on the
front".
Could you clarify, please?
Jeff
