Conical steerer spacer on the radrunner is about double the length of some of the other rad bikes, I'm looking for a shorter spacer, any info appreciated. I talked to tech support, asked if they could sell me one of the shorter spacers, no luck, new rad owner, I'm  disappointed with the small number of replacement  parts the company has.

the shorter conical spacer I want thats on the rover

Have a radunner plus and want to go to a smooth street type tire, also am interested in a narrower tire. Do any of you have narrower smooth tires suggestions to replace the 20x3.3? I'm interested in a different tire for less rotating weight, less rolling resistance and better handling.  I've seen folks use a 26x2.6
tire as a replacement for a 26x4 tire with success, what would be a minimum width tire replacement for the 20x3.3.
   
thanks, Brian
