When I bought my Spyder the P.O. said it had 2" risers on it. How can I tell if it does? And after riding it for a couple of months I think I would like to get the bars higher for more comfort. Can I just add more or do I have to buy 4"? And does anyone have an idea of the cost? No way I can do the cut the bars myself mod. I guess there is a different riser mod also. Thanks for any and all wisdom you can share with me.
