Bought a new Kona Honzo DL this week. Itís colored in ultraviolet (purple) and comes with a standard black WTB Volt Comp saddle. I want to get crazy with the color scheme and I dig the looks on the Supacaz Ignite saddles (oil slick). Iím just not sure if itís a proper seat for trail riding and will it fit my dropper post? The size of the WTB is Comp 250 size S. The Supacaz Ignite come in 143mm and 155mm. Does this change in saddle make sense if so what size?
