It's difficult to say for sure as the rts-1 and team shared the same frame. It has all the right signs to be either, flat cap, piggy back shock, serial for a 16 inch June 93 bike.
My team is a 93 too, I've had many other RTS frames and have another to build, but I've had it converted to disc only rear for a bit of fun (have the og rear just in case).
What are your plans for it? Polish, redecal and period or something else?
Mine is a retro mod, I've built it up in various guides, currently m952 with avid ultimates, spin wheels, 32mm Sid world cups and some retro controltech finishing kit. I love it, won't sell.
If you need any help or advice, I've rebuilt many bolt by bolt so know my way around them.
Check the rear pivots and BB welds for cracks, if all's good, welcome to the RTS owners club.
