i've been in the hunt for a new track frame, and r&a cycles in brooklyn have the '09 s-works langster in my size. from $1,100.00 down to $750.00. there are plenty of options out there, but i like this model over the newer specialized langster because of the relaxed geo and it uses E5 Aerotec alu over A1 used in the recent model. has anybody here used the bike? any feedback would be helpful.
