Great bike - I had a 25.5 model.
Only issue I had was ghost shifting when standing on the pedals - you will note few bikes have chainstays as long as the 700, so I attributed the shifting issue to the rear triangle flexing (although I’m a pretty big guy). Tried a few derailleur setups with same results, so I ultimately sold the bike.
Original had suntour superbe tech rd. Read up on this one if you want to go down that road. Issues keeping the upper pulley and knuckle lubricated and clean - no replacement parts. But I found it very smooth shifting, due to. The direct pull.
I have a superbe tech long cage in not bad shape with a bin of spare parts that I would let go for a song - so PM me if you are interested.
