Bang for buck;
Option 3 for me.
I ran some nice wheels on my SWorks tricross with 10 speed da mechs and 105 flightdeck shifters and it was fab, it didn’t stop, but it rode great. If I’d changed to bar ends and the right levers it would have been aces.
What would be the best way of upgrading an alloy cantilever CX frame for maximum performance, relative to price?
Option 1: Vintage Dura-ace 7970 10 speed Di2 and some Avid Shorty Ultimate cantis
Option 2: SRAM Red AXS drivetrain with Magura HS33 brakes
Option 3: Bar ends and carbon wheels
The answer will need to take into account parts availability, down shifting speed, price and comfort.
