Can 650b Wheels Improve My Gravel Cycling Experience?

Question

I've heard of 650b wheels on gravel bikes. How will they enhance my gravel cycling experience?

Answer 1

650b wheels are smaller and traditionally, riders have relied on 700c wheels which makes the overall gravel cycling experience much less for those bikers especially older gravel bikes with limited tire clearance or a cyclocross bike. It is because of the lesser wheel size that one can fit in wider tires which can help in providing more comfort and better handling in muddy or sloppy conditions. While they may not roll as fast as the bigger wheels do, these can enhance the overall experience of the ride and now, that’s the beauty of cycling.

Road tubeless was junk when I tried it. Off-road I use tubes, I can't afford multiple sets of wheels or to change the sealant every time I change the tyres.

Oh, and while 650b and 700c might be the most common on new, expensive bikes in the West, 26" is still be far the most common wheelsize worldwide.

I come from mountain biking, so have years of running tubeless with no issues.  Really enjoy gravel and bikepacking these days.  I run 700C x 38mm slick for mixed riding and swap to 650b x 55mm “medium tight” knobbies for bikepacking, single track and muddy or rough gravel.  Tubeless Rene Herse tires on an OPEN WI.de.  Rode the Oregon Outback trail from California to Washington state on an unsupported 380 mile long route.  Very fun trail with all types of gravel and the 55mm were great - cushion and grip!
You might do a future episode on sidewalls and how supple casings can give you comfort and still keep your speed up.

I ride a steel frame gravel bike with 650b x 47mm tyres, tubeless, 2.6 bar in front, 3.0 at the back. Its always funny seeing roadies' confusion when they see me keeping up fine at 30kph.

Currently cutting the difference on my 650b setup with slime tubes. Yes it can be more trouble if i go low pressure, but im on paved trails 80% of the time with my ride. They cost more but with fast rolling tires it is less trouble than worrying about punctures that strand you out in the bush.

Now, 700c goes up to 50mm are the days of the 650b numbered? Tubeless for the win!! Road tubeless not yet for prime time. I've heard Muc-0ff is working on something.

Although 650b will give you more clearance with a wider tire, it will not be as fast and you will end up working harder to keep pace.

Tubeless on 700c x 45 love em. Plenty of gravel here in Aus.

Great tip on the 650B’s!

Most people in the North East don't ride 650b, I don't know one person who does. However who cares just enjoy whatever you ride. And tubeless yes! I have gad fails and I have had saves from it. Only way to go in my opinion Francis.
