Less than 6 weeks till our next trip and we decided to try the new bikes on the bike rack....they don't fit! Hubby's bike is fine - if we put his on the outside rail we can use the existing bent arm block to attach it, but my step-through bike is more problematic. Without a crossbar obviously I need to either clamp to the seat tube or get a frame adapter to make a crossbar (I'd prefer using the seat tube). Seems there are load of different Fiamma arms/blocks - which one do I need? It'll be going on the inside rail (the one nearest the van). Anyone have any experience of putting a step through bike on a Fiamma rack?
