just over an hour to take the rear off and have the drive on the bench, getting good at this. some would argue that this is not an original idea since they already used the concept in a previous campaign. they are very popular in track and running sneakers. there it can be in demand. no need to remember shift patterns during a turn. of course, not everyone starts on an equal footing, and some people need to work harder. i would be happy to take it off you. there may be additional charges for alternate shipping services.
