Reviews
The detail on these handlebars are exquisit, the tops display a loverly carbon layup, the momo racing team partnership is a unique cross over and the branding is subtle and classy. Easy to fit, but be aware cables are likely to need replacing as they will require cutting, and oil to be topped up afterwards

Q & A
9 questions answered
Will this fit the Supersix Evo 2020 model?
Hi Gerard, I'm afraid not. The SystemBar R One routes internally through Cannondale's Delta steerer and is electronic-shift only. The Delta steerer arrived with the fourth-generation SuperSix EVO in 2023, so a 2020 EVO (the round-steerer generation) isn't a match for it. If you're unsure which generation your frame is, send the details via https://www.sigmasports.com/contact-us and we'll check. Many thanks
Would this fit a Cannondale CAAD12?
Hi Kev, I'm afraid not. The SystemBar R One routes internally through Cannondale's Delta steerer and is built for electronic shifting only, so it needs a frame with that Delta steerer setup. The CAAD12 uses a standard round steerer, so it isn't a match. If you let us know your bike via https://www.sigmasports.com/contact-us we can point you to a handlebar that'll fit. Many thanks Joe W
Will this work with last years Cannondale SuperX 3?
Hi there, Not as your SuperX 3 is set up, I'm afraid. The steerer itself is a match (both use Cannondale's Delta steerer), but the SystemBar R One routes internally for electronic shifting only, and the SuperX 3 runs mechanical GRX, so the cabling isn't compatible. It would only work if you moved the bike to a wireless electronic groupset. Worth knowing too that the R One is rated for road use rather than gravel or cyclocross. Many thanks Joe W
