When MTB's launched there had been an immediate prior fad of 26" BMX cruisers that used the beach cruiser tire size, so that was the only near adult size balloon knobby. Getting tires made was really the limiting factor. All the other fabrication stuff is just bending and mitering. The wheel machine can bend the rim extrusion to whatever size. But a tire mold is a big expensive tool requiring big corporate support to make and use in a big factory

27.5 got a reprieve this year thanks to some major companies making "mullet" bikes. But this time more than ever it seems like churn for churn's sake, especially since this time it's back to a pre-existing tire design. They did not come up with new width, tread, carcass, etc. It will be tough to see how this succeeds in the market since the whole market is in a nose dive right now

Agreed. As a guy who rides and loves his 26" mountain bike, there is nothing, and I mean nothing, that it does better than a modern 29er. There is ZERO reason why a person without special needs, should buy a new 26" bike. Today or tomorrow.

29er are now dialed, and with the modern geometry and design, are phenomenal.

The best hardtail bike and best full suspension bike for my cross-country riding needs, and in my price range and available to buy at local shops, came with 29" wheels and tires. I could have gone with a different bike company or paid to have new 27.5 wheels and tires but chose to stay with the 29" wheels. If I was a downhill racer it would have been a different matter.

It is a different selection pool for 27.5 versus 29 inch wheels. There are also more tire options at this point in time with 29 inch wheels.

Yes a 29” wheel will roll easier over obstacles etc but a 27.5 will accelerate easier up hill for sure.

And those were all good changes.

Which is why all the XC racers are using 27.5…. Whoops, never mind.

A 27.5 can also turn tighter on narrow trails.
