So what brands does your favorite bike shop sell* in your town? commute route by river shore or over hills?

*trek? they sell those, here too .. 300# people will have a need for more wheel truing

and maybe should have the shop substitute wheels with 36 spokes if the factory pick, chose less.

a triple crankset with a substituted small as fits Granny gear will help
though you may be walking the hard part of hills for a while.
(I still do)
