Not that I was aware of. It happened once in a race and once in practice. I always check pressures before riding and typically run 15/16 front and 17-/18 rear @145ish lbs. Never had this issue before and assume it might have to do with the sidewalls not being very stiff or sealing good. I will also note that for the most part they are great tires and fast. šŸ™‚ ---

Finallyā€¦. Also received another set of Nextie wheels that are even lighter than my other pair. Give me a week or two to get the testing completed. šŸ™‚ ![IMG_1882](https://global.discourse-cdn.com/trainerroad/original/3X/d/9/d9090cad9740f33cd0a7cb980dd6f0bb31696df1.jpeg) ![IMG_1885](https://global.discourse-cdn.com/trainerroad/original/3X/b/a/ba2d790621efe4a84daad3a7aecc8abd6e8542db.jpeg) ![IMG_1884](https://global.discourse-cdn.com/trainerroad/original/3X/b/2/b2d1b9dfb587e6be60875e2eed60d2abbb6d4d26.jpeg) ![IMG_1883](https://global.discourse-cdn.com/trainerroad/original/3X/2/d/2d7f776da51f503e9d409d24ddf0f76ea85b1d21.jpeg) ---

Which Nextie rim did you go with? Iā€™m in the market for a new wheelset and Nextie has made the short list. ---

Iā€™m over a year into riding the Omega 36Uā€™s. Laced em to a pair of hubs I already had so I canā€™t comment on their house brand. Theyā€™ve been pretty bullet proof for lightweight rims. I had one race where I broke a spoke 5 miles in and was ready to pull the plug whenever it started rubbing the frame. Made it 32 miles of this: ![image](https://global.discourse-cdn.com/trainerroad/original/3X/5/c/5c9aadc0b9f49666d9d0523059dcb3d5a1897d3e.jpeg) With zero rubbing. Popped in a new spoke when I got home, been holding up perfect ever since. ---

Decided to go with a Pirelli Scorpion RH in the back and RC in the front. For those interested, be ready for very difficult tires to seat , like extremely difficult šŸ˜‘. ---

Whatā€™re some good recs for lots of loose over hard, which predominates here in CO. On my gravel bike I really like WTB Raddlers, which have a lot small central knobs but BIG side knobs. ---

Barzos or dubs are what I have ridden and liked in those conditions. ---

Thanks Sulliesbrew. Checking on line, Barzos look pretty good. Dubnitals OK too but maybe not aggressive enough tread-wise for deeper loose stuff. ---

Iā€™ve been riding Dubs here in CO, but Iā€™m probably going to pick up a pair of Trinotals for a fast tire with a little more aggressive tread in the looser stuff. Iā€™ve been riding the Dubs so far in primarily places where the extra grip is less necessary. ---

> [@Saddlesaur](#): > > Dubnitals OK too but maybe not aggressive enough tread-wise for deeper loose stuff. I got some Dubs to test out pre-season and on a whim also threw in a Trinotal. Put the Tri on the front, Dub in the back. The grip on the Tri is substantial. I was riding out in the high desert a couple weeks ago and was railing flat corners. Itā€™s pretty awesome imo. Now, I gotta test it in the wet, which Iā€™m less optimistic about, but weā€™ll see. RR isnā€™t too bad comparatively, but even so I was able to set some pretty big PRā€™s across a course Iā€™v ridden quite a lot. All that said, I havenā€™t tried a Dub in the front yet. Iā€™ve tried every other ā€œfastā€ mtb tire out there except the new Scorpion. This set up grips better than everything else Iā€™ve tried. ---

Iā€™ve been racing Schwalbe Ricks and they are great if you really lean them in the corners. Many people I ride/race with want something grippier in the front like a Racing Ray or Rekon/Rekon Race. Barzo would be a great front tire also. Very few of my buddies are riding Conti XC tires. A lot of my gravity friends like the Conti gravity tires. ---

> [@kelseyh](#): > > a pair of Trinotals Haha! We cross posted. Glad to hear someone else is on the same wavelength. I bet two Triā€™s would be crazy. I honestly felt like I was riding a lightweight gravity tire. It hooks up really well. ---

Iā€™m sure there is more to it than just rolling resistance. For road bikes I can see how toe overlap could be a potential problem. For mtbs and thight single track 29ers could still be faster despite rolling slower. But agreed, Pros canā€™t ignore 5W on pavement let alone 6-10W offroad. I wonder how that would translate to road tires in 32mm for example and what implications a 32ā€ road bike would have for bike fits for, letā€™s say, Jonas and Remco. For me as a hobbyist Iā€™m in awe at the level of testing jkarrash is doing here. Itā€™s interesting to look on from the sidelines. 5-10W less rolling resistance isnā€™t getting me to sell my bikes. ---

I was being facetious about selling my bikes, but 5-10w is absolutely a massive difference. If that really is a preview the data thatā€™s coming down the line, every racer 5ā€™8 and up will be on 32ā€ by 2030 without a doubt in my mind. Itā€™ll be up to the frame manufacturers to make all the other factors fall in line. And hey, look at that timing. 32ā€ wheels just won a stage at Cape Epic. ---

> [@cassinonorth](#): > > I was being facetious about selling my bikes, oh I missed that šŸ˜ƒ I love the technicality of all aspects in cycling as much as doing the sport itself. Having forum members like john, who regularly post their science backed data and seeing this transition from 29 to 32 is so interesting to witness. I agree with your statement about most riders being on 32ā€ wheels by 2030 because thatā€™s what will be available - and people usually ride whatā€™s available. You donā€™t see new 26ā€ bikes for adults today - will probably be the same with 29ā€ in 2030+ [Previous page](https://www.trainerroad.com/forum/t/xc-race-tire-thread/49967.md?page=147) [Next page](https://www.trainerroad.com/forum/t/xc-race-tire-thread/49967.md?page=149)
