1: Different sized fenders (35mm, 45mm, 60mm), which is best for a 28mm tire. I have decent clearance on the frame, and I would rather not have over sized fenders, rather them be just right. I am betting the 35mm is the right answer, but I wanted to ask before I push the 'complete order' button.

2: SKS p35 sound good?

The size sounds right. It really depends on your bike and how fender friendly it is though. Determine what your bike will accept first. Apologies if you already know this info...
I would recommend planet bike fenders, and definitely buy them from ebay or amazon (over REI) to save quite a bit of change, no matter which fenders you choose.
If you don't mind spending a few more dollars, go support your local bike shop. They will know which ones fit and will probably even install them for free.

35mm fenders will clear a 28mm tire, but there's a problem I found with the combo. Even with a tight fenderline and with long mudflaps, you will still get side splashout from a 35mm fender in a heavy persistant rain. There's just not enough room to efficiently clear water from them, especially if you run a light tread tire like a Vittoria Randonneur or Marathon Plus.

I switched my commuter/brevet bike to 45mm fenders on my 28mm tires and now I get zero splashout and my feet stay clean and dry.

What Clifton said. I've got 35mm cascadias on my old Schwinn with 28 and sometimes 30 mm tires, and while they keep most stuff off, there's definitely some splashing that goes on. Wish I'd gone with 45s.

If you've got the clearance and the cash, Honjo makes a 43mm width in their hand-hammered and their twin-fluted models. Super mega bling!

35mm will work just fine for a 28mm tire

I just put 35 mm Cascadias on my bike after pondering the same issue. I'm using Michelin Pro2Race 25 tires, which measure closer to 27 mm wide. The fenders provide sufficient clearance but I now wish I had just gotten the 45 mm fenders. The reason is that the 35s just look kind of narrow and probably won't provide enough coverage if I decide later to use wider tires. After installing the 35s, I came the conclusion that the 45s really wouldn't have looked too wide (it's just 10 mm) but would have given me more options down the road. However, the clearance on your frame is an important issue as well. My bike is a touring model with lots of clearance for larger tires and fenders, so going wider would have posed no installation problems. On frames with tighter clearances, the 35s might fit much better than 45s.

BTW, the Planet Bike Cascadias are really nice fenders. The built-in fender flaps work well and look nice. The fenders were a cinch to install, although that was due in large part to my frame having lots of clearance and mounts.

I have 45mm on three bikes, and they look good and work well with tires both narrow and wide.
Planet Bike and SKS brands both have served me well.
Ditto on having your LBS do the install for you. The few extra pennies you pay are worth it.

Note: If they do not come with mudflaps; you really need them and can make your own and add auto reflectors to them.

I use the SKS. They'll last me about 2-3 years for me before the plastic cracks.

Thats not a bad deal for $40. I'm not expecting them to last forever.

Thank you all for your feedback, I'm going to go down to the LBS and REI this weekend to see what is available, but you've given me good food for thought.

35mm is fine, although I'd recommend the Planet Bike Cascadias. They have mudflaps.

Tape will extend the life beyond initial crackage, of course.

SKS 35 for 23c and 25c
SKS 45 for 28c and up.

I'm glad a fender question was asked because I was heading out today to find a set of fenders for my HardRock which has 2.0 tires. Will something like this work on a HardRock with disc?
