i have a wheel with this shimano hub. coaster brakes are maaaad fun.
although if youre flying down a hill at super speeds, and try to apply the brake until you slow down, the hub gets reaaaaalllllly hot, like super hot. i wanna open it up and put some thick marine grease or whatever is recommended for high temps. im pretty sure if you just lock it up and skid the tire, the hub wont get all hot. but im also pretty sure outside of like, coaster brake challenge, people that ride coaster bikes dont generally fly down big hills on purpose as fast as possible, haha.
i wonder how much the velosteel hub weighs. i heard(and believe) that theyre way better than the shimano ones.
