This wheel is a great deal. It's super light very affordable It rides very nice and has a good aerodynamic profile. They are about 32mm deep. And are close to 1500G per set. Aluminum wheels may not be quite as light or aero as carbon but they don't determinate from when you come down little cottonwood canyon. I think they are more durable and when yo do have to replace them they are 1/2 the cost. I have a couple pairs of Assault carbon wheels and some Mavics. These are nice wheels. Light enough for race day and strong enough to commute with.
This tire is light, rolls smooth and fast. Grip is consistent and great. I don't know how they wear because they get holes in the sidewall before they wear out. I have been through about 4 of these. Love the tire hate the sidewall.
For $18 what do you expect. It's a solid seat post. It may weigh a couple of grams more. So you can spend $200 more and it will still hold your seat on your bike. This is still a light post so save your money and buy it. The few grams off your seat post are not going to get you to the top any faster. :)
I hate how tight this tire is. I am using it on Mavic rims. I can't tell you how many tubes I have pinched trying to get this thing on or off. The good is it's on sales so it is cheap. But I have had less trouble getting a wire bead tubeless tire on a mountain bike. It gets the job done and it's not too expensive.
These work great for a road bike. I mostly use them on a road bike. Gets the pressure up over 100 psi in just a few seconds. Sometimes I'll use them on my mountain bike if I am lazy. I'll put about 10-15 lbs in with a hand pump. Then I'll throw a c02 in to finish it up. If I am really lazy I just use 2 CO2 cartridges.
What I like about this light is how small it is. I put this on my wife's bike because she has a fizik saddle. It' very small and not very bright but it's always there. If we are going for a night ride we put an additional (super bright) light on in addition to this. Clipped right into the seat.
I love how small this light is. I often just leave it on the bar. Then if I get stuck in the dark I can be seen by cars and get home. This light is so cars can see you. Not much good for seeing the road in the dark. It is bright enough it could get you home in a pinch but you would have to go slow and it would not be much fun. If you need a light to see the street on your bike then spend more money and get a real light. It is about the size of a wrist watch face.
I never used them. I opted for something else. But these are very long and would provide good protection for going down hill. I don't think I would want to pedal a lot in them just because they go clear to my foot. they are solid and have lots of vents. I would use them for DH.
