Built By Jerry | Grit

Grit: The Grit is my endurance and racing MTB wheel. If you ride long, fast, hilly trail rides, race XC or Marathon, or are weight and performance oriented, these are for you. These are among the lightest XC wheels you can get, and I did not skimp on the width to do it! New for late 2022 and onwards the external rim width is now 36mm with a 30mm internal. I also opted to go to a very shallow rim depth, which seems to be more forgiving to impacts, and is now down to 20mm deep. With these dimensions, the Grit can be set up for trail riding with a chunky tire on your trail bike by adding a cushcore (not included) and still being XC light at 360 grams. I always recommend a liner in modern XC rims as the lower pressure performance easily offsets the weight, and the liner greatly reduces risk of rim damage. 

The Grit is asymmetric again, after a few years having gone away from that. I find that a rim 28-30mm deep does not really need it to get good non-drive spoke tension so why add the complication? But at 20mm deep, now your spokes are more vertical and I find that these do build up much better with an offset. They are laced 28 hole 3-cross because that is what you want in an MTB wheel. I could build these with 24 spokes and they would hold up, but when you put on a modern width tire with lots of grip, the tire will start to overpower the spokes and the flex while turning will result in vague steering, which you don't want. The Grit tracks precisely and just plain rips all day. At 1275gr (DT 240) to 1375gr (DT350) you won't find anything as light and versatile with comparable performance.

All rims are constructed using graphene doped Toray T800 carbon fiber. Graphene doping is a new process using wherein a very small amount of graphene (under 2%) is added to the carbon matrix during processing. Scientific testing has demonstrated significant increases in strength and impact resistance results from the graphene doping process. My testing has shown this to be true in practice, allowing pretty significant weight reductions in the rim construction.

Additionally, these rims have an internal reinforcement at the nipple which allows the rim to be thinner between the nipples, which is a low force area of the rim. This allows the new Grit to be so much wider than the old model while being the same weight. 

If you ride a Microspline Shimano 12 speed drivetrain, check out about the XTR and M900 hubs I have.  Straight pull, gorgeous, amazing quality, and at two good price points. 

All wheels come tubeless taped with premium alloy valve stems installed, ready for you to mount tubeless tires. Through axles are not provided with wheels as they are part of the bike frame system.
