I started off wanting to re-retro my rts2, but after finding a crack on the bb, I set about buying a new frame, which turned into a nos team rts from the states. After starting the build with m95x in mind, I built it up, bought some spins, as much carbon fibre as I dared, then thought, hmm, wouldn't it look good with a carbon xtr rear mech, so after buying that, the m95x stuff looked out of place, so an m970 groupset later, and some new ceramic crossmax wheels, she was al l done. And with a spare m95x group set and spins left over, I bought another rts frame from the states and built that up. I'd hate to think what I spent, and it's probably criminal to day that I've barely ridden the team for fear of breaking it, but at the end of the day, I love how it turned out and enjoy a good pose in the summer.
I should have mentioned that I went through a good few forks before settling on the fox talas rlc forks, including some 98 SIDS, some new marzocchi marathons, some nos carbon cross links to name a few.
One expensive hobby, but no budget really as it is all about the end result (which sadly can almost always be improved upon).
