I rode my Ironman today after almost a year of riding my Apex MTB.. the bike was definitely faster and the rolling resistance is almost nonexistent, but I still felt less confident in the city overall. Going from ultra relaxed geometry with fat tires to tight geometry and 23 tires is probably going from one extreme to the other hahaha. My 89 feels very twitchy while of course the mtb feels solid as a rock
I'm thinking of selling or trading my ironman for a nice mtb now... I hope I don't get excommunicated from the centurion cult
