I'm on my second pair of the red 9 degrees float version of this cleat. The first pair lasted me just under three seasons of regular riding. I haven't had any issues with looseness, but I'm guessing the black and red versions may handle slightly differently? I'm not a big fan of the Look cleats with the rubber bottom pieces. I've found the rubber pieces come off too easily. These do not have that issue, and for the price these can't be beat. My Look cleat cover fits these great.
I like to get a workout on my way to and from work, so I was looking for something that is performance oriented but comfortable even without a pair of padded shorts. This is my third saddle in 3 weeks. First was the Selle SMP, the $XX version. Too much padding, a little too wide and just felt weird. Next was the Brooks Cambium 15 with cutout. Nice saddle if I was wearing padded shorts but killed my sit bones without a pad. Wanted to like it but not the right choice for my daily commute. Was looking for something for my Bianchi Volpe to replace the stock saddle after my first 700 miles of riding the bike. Wanted something I could ride 15-20 miles daily without needing padded shorts. After my first 50 miles or so I'm very pleased. Definitely recommend.
I have 5 Brooks Saddles. B17 TI, (2) Swift TI, B15 Swallow TI and now a C13 Carbon. I love all of them. Each has its special characteristics for the purpose I use them. I have over 800 miles on this saddle. I recently moved my Swallow from my road bike to my cyclecross bike and installed my new C13 Carbon on my road bike. A Bianchi Sempre. The C13 Carbon does fell different, a lot firmer but gives when you set back and plant your rear end firmly on the back part of the saddle. I have a tendency to ride forward when I am pushing a lot. One nice thing is you dont need to worry when it rains. You dont proofide this one like you do the leather saddles and you dont need a cover for the Swallow which is a thinner leather and can warp when wet. You try this saddle you will like it if you like one that is light and stiff yet gives a little when needed.
I will say when I went to install it on my FSA K-Force seatpost, which is a two bolt design, I had my concerns with the Brooks carbon rails. The carbon rails are thicker than the TI and chromoly rails so fitting them in the seatpost bracket was very tight. So tight you cant just push them in place. You have to pull them in while torqueing the seat bolts. The process did not cut the outer layer of carbon. They just fit really tight. All is good and I really like this saddle. Just to let you know I am not a weightwenie. I bought this saddle for it function and comfort. You wont be sorry. Give it a try.
Comparison in weight. Swallow TI 370 g (13 oz), C13 Carbon 259 g (9 oz).
Mavic rims and hubs, lots of flexibility for all possible wheel set ups. My set up came with 30mm tires and I set up my Litespeed Gravel grinder with these using 15 mm thru in front and 12 mm through axle in the rear. Now getting the various end cap set ups to work is not easy and there are no instructions. It is really just brute force to get the end caps off and to replace with the configuration you need. The tires are soft and I had two flats pretty quickly. However, the mavic tires were tubeless and I have converted to tubeless and no flats since. With the 30 mm tires the wheels since a bit heavy, but hey I am also riding over dirt roads. I am running 70psi pressure and I think that is key for these wheels to run lower pressure, otherwise you will get some flats as the tires are pretty spread out with the 19 mm internal width rims. Overall I like these wheels and they look great too.
