I was running the Trakpower 3200 Lipo's in my SWB S2, towards the tail end of Last Year, but I've just recently upgraded to the Demon 4200 35C Saddles(Part No DS4235)for the new Season.
They are fractionally smaller than the Trakpowers, but still fit a treat in the S2.......they have a kind of Carbon Fibre effect Case as well, which looks cool
