3 speed coaster hub

Not sure how comfortable it will be to have a coaster brake on a track frame as they are usually used on frames with really laid back slack angles such as dutch bikes and cruisers.

Im aware of this,
but I have been riding the track frame in question with a set of layback moustache bars for a couple of weeks, and the more upright position (to quote scoble ''sit up and beg'' position) is really comfortable,

i still have about 2inches saddle to bar drop with a moustache set up, but its very very comfortable and relaxed,

as far as the 'harsh ride' - tis not something that fusses me

thanks for the help
