These are fantastic tires for Cat 1 or Cat 2 gravel (smooth gravel roads, up to rough gravel roads). Using the Silca tire pressure calculator, I will use the lower tire pressure recommendations for gravel roads, where the tires are smooth and grippy. If I am riding primarily on pavement, I adjust the tire pressure up 4-5 pounds, and these tires behave like great road tires - fast and low rolling resistance. They are very flexible - good on multiple surfaces - and the best tires I have used for a gravel bike. They are excellent running tubeless as well. I have put them on several bikes and will buy them as replacements when the originals wear out.
My build creates fit issues on getting a comfortable efficient position on bicycles without getting custom frame. This bike post solved 2 issues. 1. 0 degree offset Allowed seat be positioned correctly for my knees over crank by having enough seat rail to move seat forward enough and still centered on rails. 2. Post has 2 set screws to keep seat in comfortable up or down position for riders comfort/preference. A bonus of these set screws, is location. Adjustable very easily with access in front of post. I have had issues with Single bolt seat posts not keeping seat level after I set. Seems you hit the wrong bump and seat goes out of position. I could not justify the price difference doing the carbon model of this seat post, A couple grams saved is expensive. It is on a checkpoint so has a decoupler to smooth ride. I have had good experience with Easton products ince the 1970's.
I just received a set of the 45 width Strada Bianca Pro. Saying they were hard to mount is a insult to the phase "hard to mount" It took me two hours to mount the set. furthermore, sealing as tubeless is a slow pain in the ass. according to AI I should have used Orange Seal rather than the Peatys I used, and after over an hour there is still viable seepage at the bead, but it's getting better. I hope by tomorrow that I will be able to test ride them because the feel is really nice. I previously had tried the 32 mm width they were much easier to mount but the 45 are really flat and wide, and even with Challenge's own video it is difficult. But for sure they are easy to seat if you ever get them on the rims.
I will follow up with a ride assessment after I am able to do a ride on them
If you wear the right shorts, this saddle is amazing. The wrong shorts and it will grip down and cause chaffing. I own primarily Giordana and the FRC shorts are perfect for this saddle, but the Silverline shorts will not work. I own more Silverline then FRC's and I enjoy both shorts and do not want to dump half of my kits for a single saddle. I would say one other slight flaw is that there is not enough cover off at the edges. Those is bigger then usual (even for a cyclist) thighs, might feel some discomfort with the edges rubbering the back of your thighs.
