Commuting from where into SF? I ask partially to understand how much climbing you have to do on your commute. If coming from Marin you might consider some very different bikes. If taking caltrain and just biking to and from the train, that is very different. I have ridden a Marin Larkspur, but not the Bridgeway. The Bridgeway is a very upright comfort bike...maybe not ideal if you have hills on that 10 mile commute or face SF's famous winds head on. If hills or wind are an issue, you might also consider a bike like the Marin Fairfax, which has a bit more aggressive position.
Out of curiosity, have you considered doing the commute on your road bike? I would recommend you try it for a couple weeks on your road bike to see if you like it. If nothing else it will help you determine what you do and don't like which may influence your purchase. Doing so may make you consider a slightly more sporty commuter.
