Does the 60t chainring come near the chainstays? I have an 82t chainring. Unfortunately, it rubs the chainstays and can't be used. I have thought about putting on a 65t or 73t from a recumbent (sold at Hostel Shoppe). I replaced the stock chainring with a 56t on the outside and mounted a 39t on the inside. I then got a 41mm pipe and pounded the clamp of a front derailleur to fit the outsize seat tube and mounted the shifter on the seatstay just above the derailleur. Pretty simple and it works great. With a larger chainring, I would probably put an idler pully at the back end of the cage to maintain the trapezoid when shifting from one chainring to the other. Sheldon Brown says a 69t chainring will match gear inches with a 700c wheel with a 53t, so my Swift can do major road riding. I have gone on a 300 mile trip with my current modifications and came back only slightly more tired. I replaced the rear cassette with an 11-32t 8 speed. David
