I have to thank you guys for letting me in on the fact that you can use 7-speed Shimano shifters with an 8-speed drivetrain. I have a bunch of 7-speed DT's and 8-speed cassettes. As a result, I have been in a sort of DT period. The Land Shark worked out so well that I, once again, reconfigured my 1989 Trek 660, this time with 8-speed DT goodness.
