After a chat with Richi at Foss Fab, a decision was made to modify the cross tube once more, Richi sweated the front casting off the twin downtubes .. the plan is to move it upwards and turn it upside down, with the crossbar socket drilled out the new crossbar can be swept up in a curve to meet the rear socket on the seatpost casting .. which will be trimmed back to suit. The front casting will be set at the right height to pick up the lower tank mounts
