The standard ones needed the taper on the noodle trimming to fit snugly into the base of the shifter housing and then took on a life of their own when the handlebars were turned ,swivelling about quite a bit , the flexible ones on the airnimal in Cycle Heaven York took up a right angle bend just like the standard ones and were not affected by turning the bars. they were not the standard straight flexible noodles but were a right angle shape, i just haven't been able to source any, i tried e-mailing Airnimal but got no response. They look really good, and shifting them, in the shop , was not at all stiff.
