Yeah, that does make sense. I think that is very much what I did as a temporary measure. I mounted the bracket completely sideways on the seat tube. The lock is U down alongside the seat tube, angled slightly to the center, going forwards. A test ride will have to see if my leg rubs against it, at which point it's going in the backpack. The HB blocks looks like a pretty good idea, though will be some homely on 1979 a Trek. Maybe I should go back to Houston, and get something more commuterish. I have a C'Dale Enforcement model, that would look nice with some Armadillo fatties. Fenders would be the problem with that one though.,,,,BD
