To me, the relationship of the saddle and the handlebars is a close one. The conquest looks like a road bike/urban moutain bike saddle where it is more suited to the bent over riding position. By putting on riser bars, you'll be sitting more upright and the B-72 or B-66/67 are more suited to an upright position. That is juyst my opinion. I tried a B-17 on my utility bike, am Electra Townie. and hated it. I switched to a B-72 and have loved it. Conversly, I tried the B-72 on my touring and city bikes and the B-17 is much more comfortable on that bike. Personally, I like the upright seating position on a utility bike since I tend to use it around town.
