only ever had two scares riding fixed.
one was during rush hour, chasing down the middle of three lanes trying to get ahead of the cars pulling away from the lights into an underpass, so resenable gradient. got up to max leg spin and then tried to relax but got jolted up out of the saddle. didn’t fall but was trying desperately to stay upright whilst my legs were flailing all over the place still attached to the pedals. managed to control it, looked back and all the cars had stopped dead. prehaps out of fear, prehaps shock. not sure which but felt a right dick. its difficult trying to explain pointing just at the bike that its a fixed gear and you can’t free-wheel it….
i find that after a week of commuting on the fixed its a strange sensation to free-wheel when on the mtb. also flipped the wheel the other week because i knew i’d be riding home drunk. didn’t change it back right away and have to say i really don’t like riding SS. only one brake at the front and it’s not the strongest. realised how little i actually use the brake at all.
and i find it much easier to track stand on the mtb than with fixed.
what size gears are you running? 44/17= 2.58
