i own the sr-81 by felt
an excellent bike that was really a good deal
i rode the stink out of it this summer (about 2500 miles). wore out the bottom bracket and chain...ended up upgrading the drivetrain
the alex wheels were not that great and got replaced by my lbs under warrenty with some nice mavic cxp-21
the only real negative are the brakes....wish they were stronger
the sad thing is that my lbs stopped carrying the brand...they sold well but the company was difficult to deal with...
