I hate to say this, but I think that shop is no longer in business. I live just down the street from it and I’ve noticed a lease sign in the window. If I remember, I’ll double check when I drive by it tonight.
I drove by there on Sunday and there were “For Lease” signs in the windows. Rick Morris, the owner of Sage Cycles, moved to Utah a couple of years ago so I doubt he has much to do with the store front. He has/had three different websites selling bike parts but I don’t know about them anymore. The BBB gives the business an “F” rating due to complaints.
I just read on another website that Sage Cycles (San Antonio) has in fact closed. It looks like Rick has opened another store in Ogden, UT, maybe you would have better luck calling that store.
