This is my ideal build but I gave up some max tire clearance for a straight top tube. (pure aesthetic reasons )
Custom Ti with Breakaway system for smaller packing.
Up to 32mm (700c) and 38mm (650b) - limited by my own standover height
SRAM Rival Groupset + Red crank Cassette changes to a 11-42t when necessary
7.8kg all in at the current road type setup
