We have one of these Masi Soulville S.S.'s left (in a 20" size) and we're selling the regularly priced $750 bike at a deeply discounted $580.
We love the way this bike rides. The steel frame and fork feel great on our potted roads (well, as good as any bike can feel anyway), the slightly relaxed geometry feels, well, slightly relaxed without sacrificing too much agility, and the mildly swept back flat bars are a perfect match to the rest of the set up.
We make no secret of being single speed fans and this is another example of single speeding done right. The stock flip-flop rear hub allows you to ride with a free wheel on one side and a fixie on the other. The tire choice is perfect for an all round commuter - wide enough to allow some cushion and provide some traction on unpaved surfaces but still pretty efficient on the road.
Finally, we love the aesthetics. The curved top tube / seat stays are gorgeous, the cork grips are a really nice touch, and the colour choices are perfect. Just one left though, so act fast if it's the right size and you're in the market for a commuter.
