650b "Road Plus"... Is it fab or fad?

If you want it, great! buy it and ride it.

More options can only be a good thing surely? I only own 700c bikes...

I'm waiting for road bikes to shift to a smaller wheel size for the improved aerodynamics. That'll get them moaning for sure.

It certainly makes perfect sense to reduce wheel size. That way the CoG can be lowered, weight reduced and the frontal area reduced.

We only use 700c (nominal 622mm) because it derives from an archaic French system using 28". There is no engineering case for using that size. It'd be interesting to give some engineers (a mixed bunch though, not just bicycle engineers) free reign to design the most efficient wheel to see what size they'd use. I'm sure there is a balance to be struck somewhere between rolling resistance, handling and aerodynamics - no-ones ever investigated it properly though.

Reluctance to change and sticking to tradition just holds back road bikes.

If you're doing this to overcome poor road surfaces, you could start by considering larger wheel diameters (like those 1990s' 29 inch MTBs that were interesting until suspension got lighter and reliable) and thus move swiftly on to a suspension road bike like the Specialized Roubaix, the Cannondale Slate road and Lefty Oliver gravel bike, or just put Lauf forks on your existing bike?

Not sure your point.

29er MTBs are very much back. The reason they didn't take off originally was due to people not getting the geometry sorted (and it was in the 2000s, not the 90s).

However, 29er MTBs don't work for everyone, and nor do larger wheeled road bikes when fitted with big tyres.

650b works great on and off road, so long as you're not bothered by aero.

And suspension's fine if it gets really rough, but is pointless on road and smoother gravel, particularly with 650b as tyres always do a better job with smaller bumps.

Errr yes you do, rim brakes can't be adapted to 650b. And most of the standard bikes ever made take 622 (700c) or the old 635 rims and have rim brakes. You can only swap wheel sizes with disc brakes.

The OP is considering a NEW bike which will come with disc brakes. I thought it was obvious. It's 2018, not 2008.

Either 650C or 26" could have worked, all that was needed was to expand the tyre choice, nope instead just resurrect a long gone sizing which very few existing frames could accept which means as highlighted perfectly by the OP, buying a new frame/bike.

I already have 40 and 42mm wide 700C tyres that work perfectly fine on my 18mm wide rims, my frame will accept 55mm wide 700C tyres if I so wished (sans guards, 48mm with) so I don't need to buy another frame that is heavier, more unwieldy than what was being sold 10 years ago and to boot more expensive with lower spec components.

yawn!

Go try a bike with WTB Horizens fitted - you'll be in for a nice surprise.

Yes there are all those other sizes around, but the point about 650b is that with a wider tyre the outer diamter is the same as 700x25/28. So what you might say, but for smaller riders like myself 700x50 just doesn't really work, plus they weight more.

My gravel/touring bike has 700x43, but I'd much rather have 650x2.2 given that the forest roads can be pretty rough. My commuting bike has WTB Horizens, and it's absolutely brilliant for blatting through town - don't need to worry anything like as much about rough surfaces or pot holes, and it rolls really quickly.

Also, there are very few decent quality larger volume tyre options for 650C or, 26" or even 700c (except for off road tyres in the latter two). Previously if you wanted to go big volume with a road tyre, you had to put up with a heavy and slow rolling city or traditional touring tyre.

Now, thanks to WTB and a few others, there are some light and really fast rolling big volume tyres available for 650b wheels.

oh and there are no lowrider mounts on the Whyte nor many other 650b bikes which my 10 year old frame does not to mention the Whyte has 'alloy' forks, no wonder they need wider tyres!

yawn again!

The days of loading up your bike with excess metal before you even start to strap any bags of stuff onto it are gone.

Why carry stuff and weight you don't need to? Hence all the lightweight touring stuff available that don't need fixed mounts on the bike.

You need to get some sleep or maybe you have narcolepsy?

I don't need to try 47mm horizons, if I need a wide tyre there's already plenty of choice in the 700C market and the only reason for not producing more wider tyres in the slick road design in 700C is that the manufacturers want to flog a different product, it's not hard to fathom is it! YAWN!!

This could have been done with 26"(557) or 650C (571) size, 26" was the go to size for off the beaten track touring/continental rides as they were easier to find in remote places, now try finding your 650B tyre in the back and beyond, you imply won't! There was absolutely no practical reason to switch back to 650B other than to promote sales of a different type of frameset/bike.

And my point was you get less practical framesets, lower spec and a higher price coompared to even just 10 years ago, for those that want to have low riders it's at very little cost to the manufacturer and indeed using cheap shit alloy forks means the ride is not as good as steel or indeed CF. 

650B is a fad manufactured for sales alone, it solves no problem, it doesn't aid reliability, it doesn't aid comfort over what already existed and indeed limits availiability in a bog standard high street store or somewhere really remote.

YAAAAAAAAWWWWWWNNNNNNN.

As it's been said many times before, 650b is a wheel size that allows you to run higher volume tyres on frames designed originally for 700c without upsetting the geometry and handling, as tyres on both wheels are of a similar diameter. It's just another option which allows more open minded people to experiment with different setups  suitable for their type of riding. It's difficult to understand why anyone would be so worked out about having more choice...

You seem to very ignorant of other people's experiences and preferences and mistake your very own personal  opinions for the reality. There is a big difference between holding an opinion and being opinionated.

All my yawning is because you're like a stuck record and it's getting rather boring.

You do seem to believe that manufacturers just push things for no reason other than sales. To a degree this will be true (they only exist because they sell stuff) but they can only sell things that people want to buy - partly the demand is created by marketing I accept, but a bad idea will generally get found out, and pretty quickly these days.

Also, first rule of marketing is to only advertise something when there is a market for it - i.e. no point advertising something for christmas in January. Companies will only begin to create products for and market them once they beliveve there is a market for that product. They will prove there is market either through surveys/consultation etc. (in the case of a new product), or they will spot a developing trend and try to capitalise on that. The latter is the case with road plus.

As I stated, there are loads of wider 700c tyres, but they are heavy (for various reasons), and the lack of lighter options here has nothing to with with marketing - it's because most people held firmly to the believe that narrower was quicker. Not only that but most frames would only take up to maybe 25c. Better quality 700c tyres would simply not sell in numbers high enough to make their production viable.

A combination of things opened people eyes to the fact that 700c and narrow tyres may not be all it after all - people trying differenct wheel sizes on MTBs, research showing that wider is in fact faster (in terms of rolling resistance anyway), and then disc brakes allowing people to change wheel sizes in the same frame, allowing people to try stuff out.

Actually, no! 650B/Road plus came about because they can fit into many existing 700c frames (my carbon disc road bike from 2013 will take 650x42 without any problems, but as it was designed at least a year earlier when road plus wasn't a thing, it's entirely by accident). Once people started playing about the manufacturers realised there was a market for specifically designed frames that will take 45-50c or greater 650b tyres and so started to make and market them.

Nothing to do with 650B - that's the exchange rates etc for you.

And man never stepped foot on the moon, there was a second sniper when JFK got shot .. you carry on believing your conspiracies, whatever floats your boat. 

Oh, and 650B is actually an old wheel size originally used for touring etc., especially in France. Nothing new about it.

I will agree on your last point though. If you're going into the middle of no-where then the spares that are most likely to be found should guide your choice of equipment, inc. wheelsize, and yes, 650B spares are likely to be harder to find, but then you'd also stick with cantilever brakes and most likely go full steel frame too.

However, the praticality arguements when in outer mongolia or such like aren't relevant here, as the OP isn't going into the back of beyond. 650B/Road plus will give them more comfort and decreased rolling resistance at the expense of a little extra weight and a drop in aero performance. And it allows you to nip onto canal towpaths or forest road short cuts without worry. 

If you're going less than 20mph on british roads, the pros completely outweigh the cons!

To be absolutely fair, it's well known that NASA got Stanley Kubrick to fake the moon landing (watch Room 237 for more info), but as Stanley Kubrick was such a stickler for details, he insisted on shooting on location.
