• @mind_maze Great, Food for thought. I was aware the 48t would be big so will adjust downwards. Hmmm will have to ponder the rear mech issue. It sort of irrational but I'm trying to avoid Sram which limits me...hence the Middleburn

  • If this is going to be a race bike, maybe go:

    • Ultegra shifters
    • GRX 1x rear mech
    • Deore 11-42 cassette
    • 44t chainring

    Should work a treat!
