I've got about 2100 km on my six month old Revive DD (21
speeds) and the plastic box that moves the pin in and out
for the Dual Drive does not want to stay in place. When it
comes off, you are left with 7 speeds and not 21. My LBG has
ordered a replacement from Giant here in the Netherlands and
I should have it within a week or two.
For those of you who have the same system, it might be worth
your while to use a plastic tie to keep the plastic box in
place. I think the shape of the frame where the box is
causes (after time) this problem. The plastic tie might
actually be the solution. Just passing this on. I haven't
been here for a while as I've had no problems and ... well,
nothing to say.
All the best, Dave Horne - The Netherlands
