Very interesting discussion and observations. I particularly liked Jan's insights.
Being down to 252 lbs (from 285 last year) I currently run the 50mm Supremes on my Atlantis with 36 spoked Dyad rims and 35mm Supremes on my Homer with 32 spoked Open Pro rims. I didn't like the feel of the 65mm BA tires on my Bombadil and couldn't really tell any significant difference between the 50mm BAs I used for a while in the summer when I got the Atlantis and the 50mm Supremes I put afterwards for their lighter weight and added protection. I could do a side by side comparison as I have two sets of Dyad wheels, but haven't yet. Here is my question: Will the width of the rim play a significant role in how a tire feels, or for that matter, hoe the bike will feel? I find that the Homer wheels are a bit flexy but only notice that when climbing out of the saddle since the front tire rub the fender somewhere. I've thought of putting the same tires on the second set of Dyad rims but was wondering if I'm going to gain anything from the wider rims with more spokes.
