Doubt you hit 40, as I used to have a speedo on my fully rigid Trek--anything over 25mph on woodsy singletrack felt insane. Even thirty on loose gravel should be a mind bender. You just trim the brake a little on a loose spot---and youll be picking your teeth out of your choice of roadside object. ![Cheesy :D](http://www.tekforums.net/Smileys/teksmileys/cheesy.gif)
NOT OFF ROAD, YOU CRAZY BASTARDO!
ON THE ROAD... F*CK ME, IT WOULD BE IMPOSSIBLE OFF ROAD TO DO 40 ON THAT BIKE! Id have stacked it without quesiton

you have no idea how f**king steep the road leading from the off road sections to the feeder road were... id love to take my geared road bike on it.
EDIT: 25-30MPH on a fully rigid is more than possible off road... ive done it more than a few times and remember the fastest run for a very long time on mammoth mountain was set by David Baker on a fully rigid GT!
