There is nothing like a good wheel size debate to get the internet in to proper melt down. Most people either fall in to the early adopter camp or the die hard 26" camp.
Over the past year I have had some great opportunity’s to
try out all three current mtb wheels sizes and here are my humble ramblings...

I have ridden modern MTB’s properly since 1992 and I have
always been an early adopter to any new technical advances. My first full
suspension bike was in 1993, admittedly it wasn’t that great and I went back to
hard tail, but when Proflex nailed it with the 954 I never looked back.
When it came to wheel sizes I have never been anti, just I
couldn't be bothered to invest in it. Changing wheels is not like fitting a
suspension fork or a disc brake, to run bigger wheels you have got to change
wholesale and getting bigger hoops was just not that important to me.
I first rode 650b in Lake Garda this year and to be honest
the difference is not really detectable, the bike I rode had lousy tyres and a way too narrow
handle bar (not to mention euro brakes) made more of a difference to the ride. I once actually
measured the rolling diameter of my 26” summer tyres and they come up as big as
XC style 650b tyres, so the difference is negligible. Still, the 650 hoop like
for like is bigger and you (and I) may not care too much for that but for
racers that are looking for marginal gains it could mean a second or two on a
run.

29” wheels are different, there is no getting away from it
they are massive! Using this type of wheel causes manufactures headaches
because of wheel base, rear travel, chain stay length and seat tube
positioning. There are some modern bikes that have this sussed, the Transition
Smuggler being one of them and this is the bike I have spent a lot of time on.

Transition Smuggler 29" |
So what did I think? Well the 29” is the size I secretly didn’t want to like, but
ended up absolutely loving it. 29’rs were always a little awkward and would take some
modification of your riding style to get the most out of them. Not with the
Smuggler, the bike is so natural you can just get on it and ride it quick. It
just feels like a bike, not even overly tight switchbacks could upset it. I
enjoyed it so much it made me really think about what I actually want out of a
bike.
With the 650B bike the handling and playfulness of the bike is
very similar to what you like about 26”, but you will benefit from the latest
designs of suspension fork and tyres. If you are looking for a complete new
bike it makes complete sense to go 650b as this is where all the development is going.

26" bikes still rule |
Lastly there is absolutely nothing wrong with 26” wheels and
I love them! I took my 26" wheel Transition Covert to France this year and had an absolute blast.
I will say that if you want to keep running a 26" bike, don’t sweat it, full suspension
bikes didn't kill hard tails and 650b won’t kill 26”. Spares won’t run out as
the aftermarket potential is so huge manufactures will keep making parts if
people want to buy them.
Interestingly I did some data comparisons using Stava with the 29 and 26”
bikes on the same route, and the results were a little surprising. Now the data is strava so not highly accurate and I rode each bike a week apart, however the 26” bike was
quicker on both the downhill, climb and a pedaly farm track! This was not what I was expecting as in certain
sections I was convinced the 29 was quicker. To be absolutely sure I need to
ride each bike immediately back to back to try and remove as many variables as
possible.

Fun is not always about speed and hard tails are massive fun!!! |
So I had all these things buzzing through my head, wheel
sizes, data, speed etc, then it hit me, why does speed matter? The magazines
are definitely guilty of pushing the ‘it’s faster then it must be better’
angle and this is certainly true for racers but what about the rest of us, the riders that ride for fun? If faster is better, then why ride a
hard tail or fat bike, they are still fun, right?
Riding all the wheel sizes have made me realize its about the wheels, its about the bike, the rider and the experiences you have. The bottom line is regardless of wheel size if it is a great
bike the wheel size becomes almost irrelevant. I get just as much pleasure out
of riding my hard tail as I did out of the full suspension 26/ 650b/ 29er, each
bike has different attributes and can be enjoyed for what they are.
If I could pick a dream garage I would probably keep a 26”
hard tail, a 650b enduro bike and a 29er trail bike. But to coin a phrase from
MBR, just pick a wheel size and just get out and ride…
