Traveling with our Screamer is still difficult, but now possible, as it would now fit in the trunk of a taxi. Perhaps these couplings are absolutely the most faultless cycling product that may exist now . I wasn't concerned or have not even noticed the extra 1kg or so. The increased convenience is so drastic that I cannot imagine ordering another tandem without them. I qualify on all counts.
Travel is a night and day difference.
It takes a little longer than boxing or putting in a BikePro tandem case. I can have it out of the case and running perfect in about 45 minutes if not helping others and jawing with interested bystanders. It requires about 1 hour to pack. About 4 hours the very first time. CoMotion has written instructions and I have written instructions on my web site for Santana.
