Has any body any advice for loading 4 bikes onto fiamma rack on Vito/Bongo
Friend has one but unsure how to arrange clamps for 4 mountain bikes.

the newer adjustable clamps make it easier.

If he has the old set length ones then its a matter of trial and error.
Alternate the direction of the bikes, may also be easier to undo the stem and rotate the handlebars. Sometimes you may want to feed an arm through the front triangles rather than over the top of the toptubes. Drop or raise saddles as necc.
