Heck yeah! I as a fellow singlespeeder I held my finger over that category when I registered this year for a minute but realistically couldn’t do it as I haven’t spent much time on the SS this year at all. Ordered a Rick and TB for tires in 2.4 although considered Mez/Peyote combo as well. 36t seems ambitious for the single speed (I’m a 32t kind of gal) but who am I to judge as I’ll be running a 36t on my geared hardtail 
. As they say only three speeds on the singlespeed: sitting, standing, or walking. Gotta risk it for the biscuit to get out in front to get the best shot out at making it up those hills before you get stuck behind geared spinners. Good luck!

I rode the 2.4 Race Rapid Dubnitals today, and for a direct comparison the 2.4 MaxxSpeed Aspens yesterday. I don’t have calipers with me, but the Dubs were clearly a little narrower than the Aspens on the same 28i rim. At the same pressure (18.5 front 20.5 rear, 205ish bike+rider weight), the Dubs felt more damped/smoother and definitely had better traction. That pressure felt good on the Dubs but ideal pressure for me on the Aspens is probably 0.5-1 psi lower. Speed didn’t feel any worse with the Dubs on road or trail. For reference, the trail I rode with the Dubs today was typical western Wisconsin Chequamegon forest - flowy, rooty, and occasionally rocky, but not near as rocky as east coast or Colorado trails. The Dubs seem like a pretty solid choice for MN and WI racing, and I’ll probably take them to Chequamegon in September.

Have been riding with 2.4 dubs for 3 months now and overall happy, BUT got to try friends bike with 170 aspen/aspen st today and i already forgot how good these tyres are! So much more supple and comfort over rough fields, roots etc and feels you can carry more momentum through technical stuff and probably only 1-2W ( flexfitjohn chung test ) slower than dubs and ricks on the gravely stuff. Typical “cat3” gravel testing isnt probably anywhere close to bumpy mtb trails and to be honest its almost impossible to test on that kind of stuff. Probably gonna switch back to aspens for next season

ST also?
Might as well right?

I don’t. I’m currently working on Vittorias Terreno 2.4 and will have Barzo and Mezcal 2.4 next week.
New Contis def give some good options I’m sure I’ll get back around to those particular comparisons

new month - new vote round 
i went for : Specialized Fast Trak Flex Lite T5/T7 TLR XC 29x2.35 
Really curious how it compares against the Trinotal, as the Air Trak 2.35 in real life testing by John Karrasch showed it is very-very close to Dubnital, so the BRR drum could be a good comparision point…
It def looks a size bigger (and i like it) on a 30mm rim vs the Trinotal 2.4 (due to it has much round profile, while the Fast Trak is square-ish)
At the risk of completely destroying all credibility … here is the lap I’ve been testing on. Lap starts at 4:42 if you want to skip the data on Race King Protection vs. Wicked Will Super Trail on the rear wheel…how much does the WW cost you in time?

Thank you for sharing. I will keep an eye out for you at Breck. I decided on Rick XCs for the race. I promised myself I will back off on the rocky sections and take the speed everywhere else. 26 or 28 tooth is an amazing choice for Breck - smart move.
Joe, seen your posts here some so good to see the video.
I did Trans Iowa too haha. That’s a beast.
I’m curious about a couple things!

That’s obviously a twisty trail You’re riding there similar to lots of stuff here in Alabama. How hard are you pushing it in the corners? I could see two methods of this with one being riding normally where you always are using the tires traction in the turns. The other way would be to lollygag a bit going into the turns that way your neutralizing the cornering potential of each tire. I would presume the first one I stated because it seems like you’re trying to test overall performance here yeah?
-
I can’t see much of the spreadsheet you have on there… do you have temperature in any weather stuff like that along with the test?
Thx and good luck at Breck Epic!
The 26 is so CUTE!!! It is really weird spinning along at 80rpm and going so incredibly slow LOL. But you know that “beep of despair”? Well with the 26 I’ve got one more gear before hearing it. (I kinda hate that beep)
Lollygaggging. Except for a couple of corners I’m not pushing very hard. I only tap the brakes once per lap. I think this helps with consistent lap times but, it’s true, the way I’m riding the lap isn’t really testing cornering. When the track is running fast and I’m on fast tires I have to work at it a lot more. But it’s a limitation, no doubt. As is…
No and between that and the speed of the track changing I’m not able to compare day-to-day like you are. I think it’s good at “which is faster, A or B” but not at all good for getting a crr.
Is there an easy way to do this? I think I read you had to do something to make golden cheetah work off road. If it’s involved then let’s skip it…but if it’s easy maybe I could start getting a little more serious about it.
Yeah that sounds correct. Interesting about the brakes. That’s good.
As far as getting CRR from it in Golden Cheetah… maybe, but I think I know how in a separate python code i use some. Message me the .fit file (not gpx) and I’ll be happy to give it a shot.
Just a quick note: I switched out to the Pirelli Scorpion XCRC yellow label and have found them to be very fast feeling on pavement, and equally good on dirt, at least on East Coast Carolina’s dirt

I rode everything from the start to bottom of powerline and back today. Course is in good shape. Got a PR going down powerline without pushing it despite having to deal with some traffic. Power numbers are looking decent and feeling pretty good at altitude. I wish I wasn’t carrying a few extra lbs. but it’s not costing me too much time based on segment comparisons from prior years. Weather has been spotty all week, got a good dosing of rain, sleet, and hail today. Today was my last long ride, this coming week will be shorter stuff while still doing a few low threshold efforts on the climbs.

Since we’re in the tire thread…..what tires?

Whoops, my brain was in the leadville thread. Well, the switch from race king 2.2 to dub rr 2.4’s has been pretty boring. I guess that’s a good thing. I dropped my pressure a couple PSI (down to 18/16) and it feels better on the chunk and a little more grip climbing compared to the 2.2’s, but I’m probably not taking full advantage on the descents. But I really need to start banging rims a bit to feel where the new limit is and I have no desire to do that this close to the race.

Joe I had no luck with those files you sent unfortunately. Laps are way too long to make good use of with Chung method/aerolab… at least now we know haha.
FWIW if I was doing timed laps of this length I’d do less of them. Prob AA/BB and call it a day. Thx again for sending those!

Hi, has anyone used specialized ground control and/or fast trak for xc? Im looking for some wet wetaher grip, i dont want too much drag but really at the minute my confidence is low on the wet stuff so id trade a minute bit of speed for some more confidence and predictability (and therefore, speed, i hope). They look like they fit the bill and as im on a budget i can get a good deal on them if they do suit.
Alternatively, opinions on the schwalbe range? Like i say, more aimed towards slick mud - roots - wet rocks - wet everything and some loose gravel.
29" and max clearance is 2.35"
Thanks.
