#GRAVEL BIKE TIRES FULL#

5mm narrower on the side than the lugs and fits small overall the Conti XC tire is 2mm wider than the thread. The xc tire has about half the sidewall thickness as the gravel tire because they know you’ll be running the MTB tire alot lower psi. The widest point on a modern, fast XC tire is the sidewall, which puts that spot further rearward than the 50c gravel tires. Once you start making all these changes for a mass-market gravel bike, you end up designing a drop bar XC bike. It comes down to the ruining the utility of the road bike end of things as well as weight, q-factor, aero, and frame clearance. XC and gravel tires are the same thing basically. Maybe something like the Maxxis Receptor, but with WAY larger side knobs? And everyone who had >50mm tires had substantial middle knobs which would negatively impact rolling resistance. Virtually everyone at the event yesterday was under-tired, IMHO. Seems like there should be a growing market for this for any gravel racing that is more technical like that west of the Rockies. Goal: slick/fast middle, and enormously larger side knobs that don’t affect rolling resistance when not leaned over.

Getting beat to death by a low-volume high pressure gravel tire is not the way to be fast.ĭoes anyone know of a tire that looks like a Maxxis Minion SS but designed for gravel? I’d have been faster on my Scott Spark, especially with the remote lockout feature. The unevenness of the hardpack access roads, chunk rock, even slick rock, made me chuckle at the fact we were all on gravel bikes. Acceleration is enormously wasteful energetically.

Bigger tires with bigger side knobbies would have provided massive speed conservation around every turn.

More volume + lower psi = WAY lower rolling resistance when it matters the most (rough stuff, and during lumpy climbs).

Reasons I’d almost always opt for 50mm or larger for gravel, unless it’s absolutely glassine stutter-free gravel: What matters most is rolling resistance when you’re operating at or above threshold because those watts are more expensive physiologically than below threshold. There is zero doubt in my mind, a higher volume tire with lower pressure would have resulted in faster times on my 50-50 road/“gravel” (fire roads in calabasas area) ride yesterday. To heck with rolling resistance data (not saying it shouldn’t be considered, but yesterday was a striking reminder of a few things that matter more than lab RR data… and I love lab data). But I would have benefited by having them at 20psi for the bumpy climbs. I couldn’t have gone any lower psi (was in the 35-40psi range) because I was already rim-striking during descents. Aspen, Rekon Race, or Ardent Race 2.25 &/or 2.4’s would have been dreamy, or at least my wife’s 50mm Maxxis Ramblers!Ĭontext: Non-competitive but enthusiastically-paced ride hosted by SBT as a charity event in Calabasas, riding with (and getting my legs ripped off by) the front group. I rode some new 44mm Cadex tires yesterday on a new Cervelo Aspero, as a test for someone, and I was daydreaming all day of XC MTB tires. I’ll caveat my answer with: I’m 208 pounds and routinely carry 2-4 L of fluid. Also includes detailed weight and size measurements Rolling resistance and puncture resistance review of a Continental Race King Protection mountain bike tire. measured width is 51mm Continental Race King Protection Rolling Resistance Review Looking for the answer to why use a gravel tire instead of Race Kings, if they clear the frame/fork, as they might have superior tread, when not on a road.Ĭontinental Race King, 29x2.2 18.0W at 35PSI (18MPH).

Why would I (or anybody) use gravel tires on a gravel bike? According to they have higher rolling resistance than the Race Kings, I am not sure aerodynamics matter at the speeds I ride, especially since I will be on an MTB. but many of us have used them on longer MTB 100 milers and survived. Do the Race Kings have the best traction? No. Not optimum for gravel duty, but it will do. It weighs 22 pounds with pedals, and Continental Race Kings (with sealant), 25 mm internal rim width, so pretty much any 700c gravel tire will fit.

My specific use would be to run these tires, in gravel races on a full suspension XC race bike (don’t have a gravel bike, but might some day).
