My steel Peloton 7000 came with a 7 speed freewheel, it was the factory groupset on it when I purchased it, 2nd owner from new. Frame looks very similar to the Kronos.

Replaced it with a Sram Force 22 with no issues, running 28mm tires, could easily fit 30mm.

Rides super nice, what a gem.

Giant was definitely ahead of it's time, well, at least the frames built in the 90's were.
