Upgraded to these bars from SC SL-70 XPLR, went narrower at 40cm, fits me just right at 40cm. Love the AXS blips integration, I installed mine on the drops. The E1 Red brake hood integration is also spot on and the internal brake hose routing is a bonus. Love this bar!
Love the ergonomics and overall 'feel' of the bars'But' the 42 cm bar was noticeably more narrow than my other 42 cm bars (Enve, FSA, Terra, S-Works) on my other bikes.. The Zipps measured 40 cm (c-c) in front of the hoods' So, you might want to size up'
These are...definitely a splurge. But, the feel and integration with the red shifters is fantastic. The wireless blips really do just tuck in very nicely (both at the tops and on the drops), and they have an overall great ride-feel over gravel
