White Industries LMDS
Out of Production. There will be no more, ever. Sorry.
Shimano's Rapidfire shifters are extremely complex, almost impossible
to service and rather unreliable. Grip Shift and Sachs both have very
functional and reliable rotational shifters that solve the reliability
problems but can result in poor shifts to higher gears when on the smaller
rear cogs, especially as water and dirt fowl the cable. Stiffer springs
and other devices can improve the up-shifting performance but only by
adding resistance while down-shifting.
Other derailleur designs require a spring to move the derailleur
in one direction. In order to shift in the other direction the rider must
work against the spring tension. With the LMDS it's like having a spring
make the shift in both directions.
Indexing is extremely precise with the lightest action imaginable.
There's no need to hold the shifter with a "Death Grip" to make
a downshift. A light touch with the thumb and forefinger is all that's
Shimano Top Swing front derailleurs can be retro fitted with the LMDS conversion kit. The kit replaces the cable clamp arm and return spring resulting in the same light and precise shifting action for the front derailleur. The kit includes the front rotational shifter, cable, housing and special ferrules.
The rear derailleur with shifter costs $ Out of production.
The front conversion parts with shifter costs $ Out of production.
