Took the RC out today for a 'spirited' ride, first one in months. The rear suspension felt very stiff.... the rear tire felt like it couldn't stay planted. The suspension was setup at a shop last October and it felt perfect. The only changes to the bike since the suspension setup is a Jardine 2:1 TI and a new single can installed a month ago and a new rear sprocket. I double checked my weight and I'm still 225 without gear. Any idea what would cause a dramatic change in suspension feel?
