How Do 750d Gravel Wheels Ride? TESTED

[@roundroscoe6502]

sounds good to me

[@5amba]

@@sebastian-FX357Z1 Well 36" wheels exists for quite a while and they are still a good thing for really tall people. Even tho there are not a lot of frame choices out there. It was always a niche thing. But I think the gab between 28/29" (weirdly the same... both are 700c) and 36" is actually to big. So having something in between is not necessarily a bad idea. The thing is... bike manufactures are f** lazy to begin with. Usually XXS and XXL sizes are not really refined in the first place. I wouldn't be surprised if not a lot of bike companies hop on the 750d train.

[@galenkehler]

How does this "make money"? Spend a whole bunch of money to develop rims and tires in a new size, in the case of the tires having to make whole new bigger machines, only to offer an easy and cheap upgrade for existing 29" bikes to let people ride gravel more efficiently on bikes they already own.

[@libraryofpapel]

Actually agree with the video that rim diameters help riders of different sizes. Generally though I think the smaller riders are more ignored than the taller ones.

[@kingOfTheMountain76]

I question whether this will genuinely bring any real benefit to cyclists or if it’s just a strategy by the cycling industry to impose a new standard, forcing the need for new frames, wheels, tires, rims, and suspensions-like the old tale of breaking windows to create work for the glazier.

[@galenkehler]

@@kingOfTheMountain76 since it's directly plug and play with normal 29" MTB frames and forks, it seems to bring a ton of value. Opens up a ton of options for high speed gravel dual suspension, since every 29" frame and fork can immediately accept these wheels as a gravel build.

Now there will be toe overlap on bigger sizes.

[@galenkehler]

It's the same overall diameter as existing mtb wheels so won't increase toe overlap on any bike that's already designed for this size.

[@DaveCM]

@galenkehler This is supposedly for gravel bikes which are 700c. A lot of gravel bikes have some issue of toe overlap especially with bigger tire sizes.

[@galenkehler]

@@DaveCM your partway there in terms of understanding. It will largely work on bikes that are designed for wheel (total) diameters of around 760mm. You can achieve this with a 700c with a 65mm tire, or a 750b with a 46mm tire. In fact most of the early testing was done on mountain bikes because it's a pretty straightforward swap. This is actually why they chose to pursue this specific size (660mm) because it's the closest you can get with a gravel size tire to MTB specs.

[@galenkehler]

@@DaveCM if any bike has issues with toe overlap, then they're just designed wrong. And many 1st generation "gravel bikes" are designed wrong, because people indeed made the mistake you're alluding to and just stuck bigger tires on an existing road geometry.

[@DaveCM]

@@galenkehler that is my point. While there may be some gravel bike out there that does, I do not know of one that can accept a 65. The max is around 50. But, you do have a point. Some gravel bikes are nearly drop bar cross country mountain bikes. With updated clearance on the rear, they probably would take them.

[@Chunky246]

Just when we thought the bike industry couldn't become more of a joke.... So now we are going to get endless insta/youtube influencers (unemployed) shilling this size wheel as the most amazing thing ever - even though almost everyone would never really tell the difference. New frames, forks, tyres blah blah blah. 29er caused a fuss because it was a bigger difference in size, this stuff however is just a joke.

[@kidShibuya]

Awesome, another standard that stops short people from riding. It's already difficult enough to get wheels and tyres for 650b (road/gravel), but let's go larger...

[@DittersGustav]

Here they come again. Hide your wallets

[@ROZLETKO]

😂😂😂

[@maxsievers8251]

There is no penalty for using smaller wheels. This is at least true for going down to 26 inch (559 mm). When you look at the geometry charts of bike models you can notice that up to the L size or about 56 cm the constructeur tries hard to fit the wheels into the smaller frames. That's the reason for the different angles for the smaller sizes. The real ride quality as intended you can only experience in the larger sizes. So depending on the tyre size we should all be using 26 inch or 650B (584 mm) wheels. Bikes for 2 m guys look weird anyway. It's their fault not to be the same size as Eddy Merckx (1.82 m).

[@kidShibuya]

There is a massive penalty. Choice. My road bike is 650b. My rim choice is slashed and my tyre choice is basically just a few Gravelkings or GP500. That is really it for higher end tyres.

[@maxsievers8251]

@kidShibuya Rene Herse and Ultradynamico have lots of high-end offerings in 650B.

[@mellissanash7517]

If my gravel bike can fit 700x55mm tires that would mean it could probably fit 750x40mm tires. But, I'd rather take the wider tire for the better traction and comfort.

[@TheSilversurfmonkey]

Same. Been running a Tripster AT for seven years that comfortably takes 700x50 (after swapping the fork) but it all clears and doesn't pack out in UK conditions. If I was planning on gravel racing I might consider sacrificing the grip and comfort for outright speed, but not convinced they'd be much faster in UK conditions, and possibly slower on wet conditions.

As a tall man I would love bigger wheel options to be honest, anything that would give my flying brick of a body an advantage I will take.

[@evanm.2300]

Jyst put a mtb tire on a 700c gravel wheel and uts the same size as this new wheel tire combo. But atleast u can go back to regular 700 . And its easier to find wheel parts and tires and easier to sell

[@darkm4g1c]

@@evanm.2300 Been using 2.3 mezcals on gravel for years, but the rolling resistance when going from one of the fastest rolling mtb tires to a more traditional gravel tire is noticeable to say the least. I'm personally interested in the the implications of a similar attack angle with reduced frontal area/ rolling resistance compared to a wider tire. If can get the same performance in a straight line on rowdy stuff as something like a mezcal, but have something with a bit more road manners for mixed surface riding, I'm sold.

[@evanm.2300]

Yeah i do like gravel sized tire more for a gravel bike that hits the rode and smoother dirt tbh. So i do understand and agree. Its just less versitile i feel. Unless they start making a decent amount of quality mtb tires for it too. Tbh tho at least when i started riding more often and new on gravel i tried a xc mtb tire but it was too slow and heavy on the little testing i did on road to a park. I needed a light weight tire till i got in better shape. I think now i can do mtb tire. Only issue is it bottoms out my lauf fork. Most people who run mtb on the siegla have a rigid fork with zero issues. The rest on the grit dont complain. So maybe they dont treat it like a mtb like me humping it and hiting some single track and harsh fire roads. I also barley got used to my 50mm gravel tire toe overlapping my shoe. I feel like a mtb tire toe overlap would be dangerous for my bike. Unless i can fit one of those slacker headsets they use aftermarket for mtb.@darkm4g1c

Exciting. For those who are tall (prob over 6'5ish) this must be a good thing. Some ex pro roadie is due to ride unbound with this set up abd could do very well. Rolling over rough stuff on courses that are not technical, these will shine.

I hope they introduce a new hub width too! That way it doesn't just automatically fit other, older bikes. Or better yet another axle size! Beyond that I find it funny that it's 750D, since that would be a french size. Since they developed the 650b, 700c, 600a, etc. Choice? Didn't work before. They just ditched the smaller size.

[@jharris-pdxrides]

The fact it's so similar to 700c is both good and also makes them a bit moot (accidental but apt pun). For taller riders like me at 190cm another benefit I could see is less awkward looking frames. I dismiss some models that fit me just because really tall head tubes just look goofy IMO.

[@eXaviar]

I wonder how different they are compared to a 29"x2.2" MTB tyre. I do run them on my gravel although the rims are only 28" or 700c. I do get that everythin below 50mm is called 700x ?? mm and from 50 onwards, it is already measured in inches.

If the aim is an overall diameter similar to a 29er then why not just use 29er tyres wth slicker tread. Rather than gravel where extra tyre volume is great, it seems like 750d really only benefits very tall riders who are competing on the road and don't want unnecessarily wide tyres.

[@unitimmy]

32” (686mm) exists with one decent off road tire from vee rubber and a nextie carbon rim available. and it has approximately the same outer diameter as a big 29+ tire

[@qdusen]

Might have been useful to do an actual comparison of same branded/material wheels in 700C and 750D with the same width tires. Regardless, this seems like a bad idea. It will force the wheelbase to become longer and potentially create problems with toe overlap. The better way to get a larger diameter is with wider tires, like XC MTB tires. And obviously, there will be very few tire choices unlike 700C which has a huge selection.

[@KevinAdams06]

I think this wheel makes more sense for taller roadies who can take advantage of a larger wheel and improve bike fit. As for the gravel context, I don’t get how this would be helpful unless you were the most elite of riders looking for an arrow dynamic advantage over a set of 29ers. In most cases, people would be better served by the larger diameter 29er tire.

[@gaza4543]

Looking at rider hight. If they are indeed aiming at taller riders in the marketing where are the smaller wheels for smaller riders? The world wide average hight is 5,7 so it should stand to reason making 650b/c would actually be a boon for the cycling industry getting road and gravels riders on to bikes that actually fit them. They have never really tried smaller wheels on road bikes.

I hate standards changes, but I'm also really tall and bigger wheels are better. Would be nice if XL bikes came with these like XS come on 650bs. The future always trends towards more customization and I look like a bear on a basketball with current wheels. Leave the middle group alone.

[@WALDO1000]

This is clearly something that would benefit a tall rider the most by giving them a wheel that is more proportional to their overall bike size (just like 650B or 650C for smaller riders). Having an average size rider comment on the pros and cons of it is fine, but this video really needed the perspective of a taller rider to tell you how the change felt to them. I'd be much more interested to hear how a tall rider felt the larger wheel impacted climbing etc. and if they felt there was an advantage to riding with a wheel that was more appropriately scaled to their overall size.

[@DaveCM]

It makes the gearing higher for one thing. I'm 6'3" (190cm) and 650b actually feels better to climb on than 700. It lowers the gearing a bit and they just feel more agile on the climb. Everywhere else, I do not prefer them. I guess it would be a similar correlation climbing.

[@darkm4g1c]

I get the feeling we will see Connor from GCN on these shortly. Its funny, when more proportional wheel sizing was brought up for smaller riders no one batted an eye, but the second a new standard comes up people immediately start whining because innovation=bad. Don't get me wrong, the bike industry has tried to push new standards that sucked in the past, but if they never attempted to make something new we would all still be on wooden velocipedes.

[@asonetuh6094]

like crank length I think wheel size should have finer gradations for rider size. for too long the bike industry has been lazy and shoe-horned riders who are short or tall onto bikes that really don't fit them. I see this as a good thing for tall riders (above 6'4" / 193cm) but other than that it's just marketing hype. even the name itself: the "d" (which is based off of a very old French standard having "a", "b", and "c" tire variations which maintained a consistent outside diameter) is nonsensical in the era of ERTO rim designations.

There should still be a sizeable minority of cyclists who know how to use and tune a front derailleur.

[@marksandoval5361]

I'm totally into the 750d wheel size but not for gravel bikes. I would want to use 750d wheel to use on the front of a mountainbike with a 750x61(31.5x2.4) tire. If I've calculated the height correctly, that tire should fit on most forks that are not XC forks.
