I'm about to order some Planet Bike Cascadia touring fenders for my TriCross.

Here's the bike:

Here's the fenders at Amazon:

So here are the questions:

The bike has 700x32 cyclocross tires. What size should I get? 45mm, 35mm road, or 45mm hybrid? Planetbike.com is not much help here.

It seems like it has front fender mounts, but that it would have to share the rear mounts with the rack. I'm not sure. Will these fenders work?

Thanks.
