29er tire weight list
1 - 20 of 1266 Posts
my WTB Stout 2.3 came in right at 900 grams (minus the packaging)
The WTB Nano I took off the front was 687 grams, I just needed more grip in the front.

Here is my measurements list:
Notubes Crow: 439 / 478
Bontrager XR1: 484 / 489
Kenda Karma 1.9": 521 / 498
Notubes Raven: 513 / 517
Schwalbe Racing Ralph 2.25": 563 / 547
Continental Race King 2.2": 647 / 659
Bontrager ACX 2.2" TLR: 656
From 550gr upwards, I have a hard time to consider tires to be race-worthy. That's a very personal limit, very much influenced by the terrain I race on: Mostly forest conditions with little rocks thrown in. I find, there is very little choice under 550gr. It seems some tire manufacturers just do not push to low weight in the 29" department as they do with 26" tires. There are masses of 29" tires above 600gr because of that and I think they do not need to be.
The ACX kind of proves that. Full knob, pretty wide and TLR beads at a pretty good weight. Conti achieves the same weight with their Race Kings (and my pair is light!), but with only a semi knob tread. If Conti would use their "supersonic" casing, the Race King would be on par with the Racing Ralph, possibly even lighter. Now THAT would make a racing tire. We're only at the beginning of 29er specific development, I guess.
Now if we just could persuade the Germans to go and race 29ers...

Not to be a downer back at you, but this question is getting about as tiresome as is possible on every thread that the Raven or Crow is mentioned. All I can say is go buy a Crow, a Raven, a Vulpine, a Furious Fred or any other semi-slick XC race tire and give 'em a go. Then get back to us on what you discovered and found by running them. By the way, there are more tires in this category for 29"ers coming.F5000sl said:
Plenty of guys riding and racing semi-slick tires in the 26" and the 29" platforms who would beg to differ with your opinion as to how they could be considered a mountain bike tire.
Toss a leg over a pair, take 'em out on your trails and get back to us.:thumbsup: That's really the only way to answer the question.
