We need a GCN science video on this! I'm interested in an acceleration tests of a 650c vs 700c wheel both with road tires. With 12% weight reduction, 7% aero benefit, and 24% lower rotational inertia I'm guessing it could have a big impact on standing start sprints and even some decent results in rolling start sprints.

Alex Stieda rode a 650 Softride with Coors Light in the early 90's and there was some other experimentation among the Pro's. I think Steve Bauer's 1993 Paris Roubaix bike may have used 26's as well, but there a smaller diameter would increase bump force. Most notable is Paula Newby Fraser on a Hamilton with 24"!! wheels front and rear. She smashed the Iron Man record and came in 3rd among the men. 200 gm rim, 140 gm tire and same spoke aerodynamics as a 700c wheel with an 80mm rim. Ridiculous acceleration and aerodynamic and it allowed a tighter, stiffer frame. Banned by the UCI after Atlanta 96.

Thats the one! Special build for her. Notice the "uphill" bottom bracket and the apparent length of the chainstays, and the size of the rings. Some is just a visual effect of the wheels. The stays were actually super short at 38cm with plenty of room to go even shorter. This allowed stout stays with no need for crimping. The only reason the stays didnt go any shorter is because the chainline couldnt take it. I wish this design would have survived. Unfortunately it was ahead of its time. It would put deep dish carbon wheels out of business and put a few thousand $$$ back in your pocket.

That was fun. I bought a Cannondale Topstone gravel bike that came stock with 700 wheels. Also bought a set of 650b wheels at the same time and immediately started using them as my regular wheels (with various 47mm WTB tires). For most of our gravel, that comes close to switching to a mtb, this is the best option for the gravel bike. Great to have options. Ride what works.

Have you measured the overall gross diameter of the two different wheels and compared? I have a 700C bike on which I would like to run 650B, but want to make sure the diameter isn’t an issue. Ideally the 650B is a slightly smaller diameter. On my particular bike diameter is a big deal. Thanks!

Owning both 700c (w/ 28mm tire) and 650b (w/ 43mm tire) wheelsets for one of my bikes, I can say that the bike handles very differently when I switch. I attribute this mostly to the lower bottom bracket when using the smaller wheel. That lower center of gravity feels much more stable on the road, but also comes with a higher risk of pedal strike if I lean over too far in the corners. Both are fun, but putting fat 700x40mm tires on is the most fun.
@alantaylor66916 жыл бұрын
Really? I would have thought that the overall diameter of both those wheel setups would have been very similar. I mean a 700c x 35mm tire has the same overall diameter of a 650b x 47mm tire. In fact I would have though that your 650b x 43mm setup might even have a slightly greater overall diameter. Is that not the case? I'm interested as I myself am looking to do the same as yourself for my Giant Contend Disc.
@alantaylor66916 жыл бұрын
Well it looks like you are right, your 650b x 43mm would be a little lower. Here is a conversion table to just found: 700C x 23mm = 668mm = 650B x 42mm 700C x 28mm = 678mm = 650B x 47mm 700C x 32mm = 686mm = 650B x 50mm 700C x 35mm = 692mm = 27.5 x 2.1” 700C x 38mm = 698mm = 27.5 x 2.25” www.bikepacking.com/gear/700c-to-650b/

Tech Question: With 700c x 28mm tires on my road bike, I have approximately 3mm clearance on each side of the tire (inside the fork/chain stay/seat stay). The angle of the frame-inside the fork/chain stay/seat stay-increases as it nears the hub. A smaller wheel accommodates a wider tire because its shorter radius sets the tire at a wider point in the frame. The radius of the 700c-from hub to rim-is 311mm (1/2 of 622). The radius on a 650b is 292mm (1/2 of 584). Measuring 292mm up from the hub, I find there is approximately 41mm width inside the fork-where the edge of a 650b wheel would sit. Without knowing the height of a given tire, what's the largest tire my frame can accommodate using a 650b?

My experience: I own bikes with 700Cx25mm all the way up to 700Cx42mm tires, 650Bx42mm and 48mm, and 26" x 2.3" (American sizes, sorry there is no metric equivalent, although you could say ISO522x58mm). I'd say the fastest is 700x32mm (on a ~30mm wide rim). 650x42mm is the traditional Randonneur tire and is great for distance. 700x38 mm is my favorite as it's pretty plush and rolls quite fast. 26"x2.3" is great for multi surface riding -- I run them at 25PSI and they are at their best on hard pack and super rough roads. I only use Compass road tires (no knobs), and only ride tubeless (except 650x42mm), so this will be a different experience than with the heavy WTB 650Bx47mm tires.

Very nice job, thank you for the thorough discussion! Two minor quibbles: First, regarding the use of bead diameter to designate size -- it's the crucial diameter that must be matched by the tire. The other diameters (e.g. to the very top edge of the rim) are inconsistent between wheels that would take the same tire. Second, right around 9:00, you suggest that one could make the steering less ponderous by increasing trail -- I think you meant by decreasing it (or by increasing rake perhaps)?

To make things more complicated: a bigger wheel and tire with better brakes up front. The rear wheel is dragged over an obstacle (front is pushed over, which is much harder somehow) and is more easily controlled when you lose traction. The front wheel takes about 80% of the braking too. When converting from 26" mtb with rim brakes, it was common to upgrade the fork to a 27,5 or 29" disc brake with better shocks. Best of both worlds. Even today it is common to see 29" front and 27,5" rear on some mtb's This will only carry over to gravel bikes with big clearances in the forks though. You could save some money going for a 650b rear wheel only. Keeping the front 700c. It could also make the geometry more relaxed when running the 650b, a good thing on gnarly gravel.

I need some clarification on something! I've read posts where people claim that a 23mm 700c tire is equivalent to a 38mm 650b tire. This confuses me! I understand that 23 and 38 are referring to the width of the tire and not the height. The total diameter, according to your video, of all 650 tires is 650mm and all 700c wheels would be 700mm. So the height will always have a 5mm difference? I must be missing something. Can someone help elaborate on this.

To be honest, unless you’re looking to do CX as well, or explore off-road, this video shouldn’t really influence your buying decision. With how comfortable and light modern aero bikes have become it’s hard not to recommend one (especially if you’re running 25 to 28 mm tires) if you’re fine with the slightly more aggressive geometry.

If you have a multipurpose bike that can swap wheels/tires to handle a little off-road, does the wider fork have any large impact on aerodynamics? it sounds like it might be possible to have one bike with swappable wheels that does more for less money than 2 bikes. But if it the trade-offs dramatically worsen road performance, it might still be worthwhile thinking about 2 bikes instead of 1.

Hi Pavel, thanks for your message! Unfortunately this is a question we can't really answer for you! If you need the chunkier tyres for more "gnarly" roads/off road sections, then your best bet would be to use the smaller wheel. However, if you want to use this bike on the road, or if the gravel/off-road sections you ride are less technical, then you would probably want the 700c option. It's very much personal preference, based on the conditions you ride in. I hope this helps :D

If it's the other way around (i.e., you have 15mm thru-axles), you can sometimes find new end caps to use wheels designed for 12mm axles. Also, note that you REALLY need to pay attention to the outer diameter of the wheel/tire combo. If you put a 650b x 42 mm tire (the most common road tire for 650b's) on a bike designed for 700c x 25/28 tires, you may have horrific pedal strike issues (it's 10mm smaller than a 700Cx28, 4mm smaller than a 25mm and, thus the same as a 700Cx23mm).

I forgot about that issue, which has also been a problem for me. The 142mm standard appears to be the most common, and there are end caps to make 142mm into 148mm, but they are hard to find. In my case I was able to get my front wheel from one bike to another, but the rear wheel was too narrow and I couldn't find end caps to extend it.

Once tyres are fitted on both 650b and 700c Won't they be the same size with the 650b fatter tyre?

Does switching from 700c to 650b can lower the ground clearance?

With all the current "options" in wheel/tire...is there any advantage to use different tire width front/rear? I'm currently on 23c, but got a 25c and a 28c, same brand/model, new ones. Where should I put each? F>R or R>F? #torqueback

Erik Castañeda F>R is what mtbers often do because you really don’t want to slide the front out.

I've had a 700c on a 29er wheel set worked just fine. 700c come in tire types that 29er dont try getting a road slick in 29er 700c are all over the place cheap

You guys mentioned coming from the old 26" MTB cross-country days. Other than the obvious drop-bars and shifters, how would my 26" MTB hard-tail be that different? Is what's old, new again?.... Also, wtf is Si drinking? Cider?

So with all that said, would it be better to run 650B a fatter tire in the front for handling and skinner 650B tire in the rear so less to push while peddling??
@HaloTupolev6 жыл бұрын
You're pushing both tires while pedaling. Just because a tire isn't part of the drivetrain doesn't mean you aren't using your power to accelerate it and keep it rolling. In terms of aerodynamics and suspension, it's probably better to have the skinny tire up front (where the aero contribution is more significant) and the wide tire in back (where it's usually suspending more weight). Bikes that run bigger tires up front are, to my understanding, usually set up that way for handling reasons.
@tedgodfrey27086 жыл бұрын
Just my case, I thought the only time to run the 650B are when you are going more off road than on road riding that day.. I agree about the aerodynamics, but when you are flying down a rough trail at different speeds off road you would need the bigger tire up front..

How do you fit the 700c on 650b rims? I have mtb and I bought 700x35 for my 650b rims, but the tires look way too big. Any tips?
