    Continental Mountain King II RaceSport, the 580 gram, 2.4" version

    Anyone Rollin' on 26s? I'm riding a SC Nickel, heavy XC to light AM and not really any rocks or roots to worry about around here. Do you guys like them? And, do they Ghetto up well?

    Don't think the 2.4 is 580gm. The 2.2 is around that weight. I just ordered one to put on the front not of my TRC. But it's going to be awhile before it hits the trail. Bad weather and waiting for sc to send me a new frame.

    Those are the tires I run on my 26" Evil Sovereign. I did weigh them and I know they are more than 580gm but can't remember how much...

    I run them tubeless on Easton Haven wheels right now, with about 20lbs of pressure. They are big tires. So far, I really like it on the front. The rear.... not sure. It's good, but I'm not sure I need that much chunk for a rear. Will see.

    Maybe I ordered the protection w/black chili. I did allot of searching. And didn't find anything lighter. Than the upper 500gm range.

    My 2.4" x 26" Mountain King II RaceSport tires I bought in May 2012 came in at 550gms and 560gms. Great grip, very quiet rolling, and quite fast rolling as well. Not as smooth as Race Kings but getting there.

    Are these OK tubeless?, I've had problems getting the protection carcass (admitedly on a RQ) to hold air. I wondered if the racesport MKII carcass is thick enough to go tubeless with?

    Conti announced the ProTection RTR (Revolution Tubeless Ready) version at Sea Otter last year that was supposed to be truly tubeless ready

    Continental Clears Up “New” Revolution Tubeless Mountain Bike Tire Scheme - Bike Rumor

    UST – traditional UST – has nothing to do with ProTection, utilizes a butyl liner and UST bead, is unchanged and still offered across all patterns. 26″ ONLY, traditional UST and 29″ don’t mix – too heavy.

    ProTection RTR – Conti’s tubeless-ready offering – combines the additional bead-to-bead casing ply of ProTection (heavy duty nylon; 4 plies under the tread / 3 in the sidewall) with a UST-style bead for RTR – Revolution Tubeless Ready compatibility. All ProTection RTR models are German-made and feature Black Chili Compound. 26″ and 29″.

    RaceSport – effectively replaces SuperSonic as a more robust, but lightweight tube-type offering, also German-made and featuring Black Chili Compound. Although experienced users are able to run them tubeless, in order to avoid inconsistency, RaceSport is not officially marketed as tubeless-ready. 26″ and 29″.

    I haven't seen the RTR versions specifically listed yet so maybe that's just a feature of all the ProTection versions now, but the MKII 2.4 RaceSports I got from Universal Cycles.

    Good tall moderately fast and grippy rear tire. From memory closer to 650gm.You'll need an xking 2.4 to get under 600gm. Not as much cornering grip as a Ro Ro 2.4 [ 2012] in the front.
    Going off memory may be slightly less cornering grip than a No Ni 2.4 and more than a 2.35.

    As a rear it sits in between X king 2.4 and TK2.2 for speed and grip.

    My MKII 2.4 RS was 631g brand new, purchased end of 2012. Setup tubeless without issues. Definitely not as grippy as the 2.35 Kenda Excavator it replaced, but 50g lighter. However, as other's said, it was no where near the 580g stated - at least mine wasn't. Don't have enough riding on it yet to see how well it holds up to agressive riding.

    Yep there sure are. You asked about the 26" Race Sport version which is the one I provided actual weight of. The one I received was 631g, quite off from the claimed 580g on their website. But to answer your question about tubeless, it setup just fine for me without issues, and is holding well.

    Yeah, gotta be two versions. I think that's to much of a difference in weight.

    And I was initially unhappy that my RaceSports weighed 10gms more than my Supersonic Mountain King I 2.4 tires.
