So, I am seriously considering selling my well-equipped Iron Horse Yakuza Kumicho downhill sled and replacing it with the Preston FR since I rarely get to ride pure downhill and I want something I can actually pedal up a hill. I know the Preston is good to go for the Shore and SST, is it a viable option for Whistler as well? Has anyone tried the air shock option on it, or is the coil-over the way to go? And lastly, how heavy is it once built? Thanks in advance!
