That's what I'm talkin' about!
This is a 29"er fork, for reference. The rim.....it is a new one from WTB. It is meant to go with the new tire, tubeless TCS style. However; this tire will fit down to rims with a 25mm inner rim width and work just fine.
Numbers? Sub-1000 gram tires, (just over 900, actually), and the rim? About the same as a Velocity Dually, (in more ways than one). When? Soon......they are real and will be available. How big? Depends on the rim width for over all width, but think 64mm-71mm wide. Diameter will vary as well, with the wider rim flattening out the tire more and the narrower rims making the diameter larger. Think about 15mm-20mm smaller than a 29 X 2.3" tire diameter. That's gonna lower your bottom bracket height a bit, so be aware of that. Costs? Don't have a clue yet.
Why? Because wider rims and bigger tires really do make a difference. A big difference. It is much betterer in a way that you cannot know about until you actually try something like this. Traction will be better. You will take corners faster. You will have more comfort and stability. One thing you will not have is a need for a new 29"er. These tires on the right rims will work in loads of 29"ers already out there. Sure, it won't work in a lot of them, but on many it will. It's going to be a big deal going forward.
I have a feeling this is just the start.......
