So for everyone who has done the trailer wheel mod, What sprocket size are you running and are you happy with your choice? Obviously, most people who do the mod are exclusively or at least mostly running off road. I'm in the process of doing it now and am getting all the parts together and want to order a sprocket from sprockets specialties. Right now I've been running the stock rear tire with a 54 tooth on the rear. Top speed is about 50-55 but cruises real nice about 45, which is fine. I ride about 90% off road and 10% on road maybe a quick trip to the store. I realize to trailer tire mod is going to require more power to turn that heavy wheel and tire. I should also mention I weigh in about 245. I'm also considering a dual sprocket (rear) so I guess I'm asking how low is too low for gearing?
