Quite like my hi-mod Synapse disc. It manages to be both stiffer than my previous TCR, and more comfortable/smooth than my ti Lynskey. The TCR was jarringly harsh, and the Lynskey felt like it had to be wound up to go anywhere. It’s obviously never going to be a crit racer, but for its intended purpose, it fits the bill for me. Mine has 28mm Pro Ones on Enve’s, so that doesn’t hurt either! I test rode a Roubaix, and that thing was dull and lifeless in comparison.
