Bottom Line:
I commute on my hardtail bike to work. I also take to the road to ride up to Pompano Beach from Fort Lauderdale. I used to run 1.9″ tires under the idea that narrower tires translated to lower rolling resistance. But three pinch flats later, and one dented rim, I decided to try the 2.4″ after seeing them on a bike at my local bike shop.

The tires are the widest I have ever ridden. I feel like I am on the Batman Motorcycle when I ride. I run at higher pressures and these tires ride faster and much quieter than the Tomac’s I previously ran. I feel less beat-up and have less fatigue on my hands and wrists.

The challenge was inflating these tires. I saw examples where people were able to fill tubeless tires with a floor pump. No such luck. These tires required compressed air. I used 2oz of Stan’s on each tire and they sealed up easily without the need of soap and water.

2.4″ is 560g
Fast rolling, outstanding resistant to pinch flats
Very well constructed

Wish the blocks on the edge was bigger for better cornering

Bottom Line:
I have used these for a about 3 months now after using SRAM X7 trigger shifters for a while. I was looking to match my X0 rear derailleur that I “inherited” when I bought a used 2005 Giant NRS C2. I am on a budget, I would never have bought the X0 triggers because of their price. I am very impressed with these, I believe I have MAYBE mis-shifted when riding, even when jumping, only about 2 times that I can remember–not counting crashes, because that happens even with triggers–Heck, I have even mis-shifted a few times with triggers when going to shift while riding and I hit a bump or something.

These lock pretty solid, shift very crisply, and prevent mis-shifts much better than I would have thought. The rubber on these is nice and grippy, especially when paired with gloves; I do not remember my hand ever slipping. The main thing I love about these is how you can go through the whole range of gears with just a flick of the wrist. Because of this, I honestly feel they have improved my riding. Another thing that is great is that they are lighter than triggers. Also, I love the microshift, it prevents chain rub on the front derailleur and keeps the bike quiet; the way I like it.

The main thing I don’t like about them is that they don’t feel quite as good as a regular full handlebar grip. I really am not a fan of the grips that come with these. You have to cut them much shorter than they come stock, or else you will have a WIDE grip area. The grips should mate up better with … read morethe edge of the grip-shifter. Because of this I rigged some old, thick foam grips with these. Also, sometimes when shifting these can slightly interfere with braking. But, seems to not be a problem, since you have 2 brakes, and you are basically never going to be using both shifters and brakes at the same time.

Bottom Line: They shift well, they are quite cheap compared to any other high-end shifters (especially at Amazon’s price), they are light, and you can shift faster with them. I definitely recommend buying Jagwire’s Ripcord derailleur kit when you buy these. That is the best way to get the full potential of these. I say these are definitely great for XC, Trail, All Mountain. May not be best for Downhill/Freeride when doing bigger jumps, although you would probably be fine. I would say definitely not for Dirt Jumping, though, seems like might get in the way of barspins, etc.

Shift crisply, lock in place well, the microshift eliminates chain rub on the front derailleur, they are light, and pretty cheap compared to other shifters ( I got them for about $68 on Amazon new and shipped!)

Not quite as comfortable as a regular full handlebar grip, the grips that come with these could mate up better
