Hi. I'm planning 105 di2 shifters , disc brakes and front/rear derailleurs. Id like to lower weight by using carbon crankset, chainrings and cassette.
Could you recommend a Chinesse options with some longer term reviews. I was thinking leese crankset but does that require an adapter for chainrings then ? And possibly a ztto cassette. But again concerned about material choice here . Aluminium v steel etc. and then I need to consider chain line but I know nothing about this.
Any advice welcome thank you
