I am thinking of getting the clubman 2 speed kick shift because I am not accustomed to riding fixed gears. Should 2 gears not prove adequate, I would upgrade it to a 3 speed with coaster brake using a Sturmey archer quadrant shifter mounted on the top tube. Thoughts?
Truthfully, I use only 2 or the 3 gears on the s3x. I'm in the midst of building another "Clubman" this one will be a 2 speed kick back and Lauterwasser bars so I think your on the right track. 2 gears is enough for some moderate climbs or short steep hills, around town or for a good workout if need be.
I like the quadrant shifter for that vintage look but they can be a pain to shift compared to the SA bar end units. I wouldn't rely soley on a coaster brake, I'd use a front brake also.
