The extender was recommended by Peter at Swift Folders. I purchased this after using one of those stems that are adjustable for angle. This is a far better solution, though if I do want to play around with different handlebars I will need a longer extender.
Also it looks like you have the shorter of the two risers. You may want to email Xootr and see if they have the longer one still available. Again I found them to be extremely helpful.
I am interested in your bicycle. Is that a Surly Tuggnut on the rear? Do you think it is necessary? I currently have 20 x 1.5 tires on the rear and purchased 1.75 tires, not realizing they may not work. I will need to move the wheel backwards and I am wondering if I may need something to keep the axle from moving forward. I was considering a Tuggnut or the Monkey nuts, or a cheaper BMX alternative.
Thanks,
