Schwalbe

I ordered a size 28 for my rim brake carbon zipp 404 NSW wheels . This is the second set of tires I purchased., not because I wore them out. It's because I first purchased the size 25 tires and they seem to be very hard and feel like they're smaller in size. . But if you don't go any lower than the size 28, you will be just fine. It does make a difference. ! Size 25 on these wheels were just way too hard so I wasted money and re-purchase a size 28 keep that in mind . Also, too when you're using tube type tires on tube type rims no problem mounting these on the wheels.. that's really important

This review is for the redesigned PRO version of this tire.

This is an amazing all-round tire with very even transition of knobs throughout the tire. It actually can hook up quite decent up front as the knobs go pretty far to the outside of the tire. Mounted on 28mm internal rim these 45mm blew up to 46.5mm WAM.

Ran this at unbound XL with zero flats and have continued to punish them on all kinds of terrain with no issues so far. Very satisfied with road feel and capabilities on chunky stuff. I really don't see why you would run the RS version now that these are so dang fast and likely better tread protection.

I had a 2.25 inch MTB tire on the front of my bicycle. I have now installed this 2.15 inch tire on my bicycle. And after a couple all day rides, I am going to say the rolling resistance is great/ easier riding. I also changed my crankset back to a 28/38/48 Acera--170mm (down from 175mm crank--30/42 t). When I am starting my ride, southbound, I use 28t to warm up a few blocks, then 38t to get moving, and then from 42nd Street to downtown (next 45 blocks) I use the 48t ring. So, I believe this Schwalbe Marathon Plus tire is a major part of the ride coordination / speed / less rolling risistance. When I am returning home mostly northbound. I use the 28t or 38t rings. I felt less exhausted last week on my ride.

If you're looking for a fast 29" tire for the tarmac these are the ones. Had been running Thunder Burt's on my 29" road mountain bike forever and they are a pretty fast tire, but on the first ride with these I was able to shave 2 minutes off my previous best time on an hour ride.

I was going to get another set of the Thunder Burt's, but checked Bicycle Tire Rolling Resistance website and saw these were significantly better so decided to give them a try. Since I only ride this bike on paved and chip sealed county roads these seem like an ideal fit.

I've only got one ride on them so I can't speak to the durability or longevity of the tires, but they probably won't match the Thunder Burt's where I had over 4000 miles on the front tire when I took it off and could have ridden even longer. But, for the speed increase and smooth road handling characteristics I'll give up some tire life. Plus, I just happened to hit a sale here at BTD so ended up saving a nice chunk of change.
