A 650b wheel is one that’s about 27.5 inches in diameter
, when measured from tyre edge to tyre edge. This compares to 26in for a standard mountain bike wheel and 29in for so-called ’29er’ wheels (700c road wheels are also 29in in diameter).
Are 650B wheels any good?
A big advantage of 650B wheels compared to 700C wheels is that
you can fit wider tires in the same frame
. Nonetheless, a common claim is that high-volume 650B tires have the same outer diameter as 700C tires, negating any issues regarding the height of the bottom bracket and ground clearance.
Is 700 the same as 650B?
In terms of total diameter (including tread),
a 650b fitted with a 47mm tyre is a similar diameter to a 700c wheel fitted with a 28mm tyre
.
Are 650B good for road?
This means for smaller riders who’ve had issues with comfort or handling of bikes (and in mine and many other bike fitter’s experience, that is nearly every rider under 5’4)
650b presents a great option for both gravel and road riders
.
What does the B in 650b mean?
“650b” comes from an old French tire sizing that indicates the diameter of the wheel from one tire end to another. In the case of 27.5′′ wheels, the number is 650 because this is the approximate diameter of the wheel. The letter “b” designates
the width of the tire
.
Are 26 inch wheels the same as 650b?
26 inch (559mm) wheels were the default mountain bike size for a few decades, while 700C (622mm) and 650B (584mm) were generally reserved for road and randonneur bikes
. This resulted in a greater availability of high-quality slick tyres in the latter sizes.
Are 650 wheels faster than 700?
A lighter wheel is easier to spin up to speed than a heavier one so
a 650b wheel would be faster than the same wheel in 700c
. Add in a 42 mm tires on the 650b wheel and you are likely losing most of that advantage.
Can you put 700c wheels on a 650b bike?
One useful feature of gravel bikes with big tire clearance is the opportunity to use both 700c and 650B wheels with the same frame
. Each of these wheel sizes offers different benefits and ride experiences suited for various adventures.
What is the difference between 700c and 650b wheels?
The difference between 650b and 700c is
the diameter of the rims
. 650b wheels measure 584 mm in diameter. 700c wheels measure 622 mm in diameter. 650B wheels are 38mm (about 1.5”) smaller than 700c.
Can you use 650b wheels on a 29er?
Yes The drop will reduce chainring clearance when doing log overs as well
. One thing you may want to consider is getting wider 650b rims and going for 650b+ (aka 27.5+) tires as they will fit a lot of existing 29ers and will not alter your geometry significantly. Anything from a 650×2.
How tall is a 27.5 bike?
What height is a 27.5 bike for? Mountain bikes with 27.5 inch wheels are suitable for
adults of all heights
. These bikes offer nimbler handling than 29 inch wheeled MTBs. Sometimes they are only available in smaller frame sizes and some shorter riders prefer the fit of a bike with 27.5 inch wheels.
What size is a 27.5 wheel?
27.5 mountain bikes, also called tweeners, are mountain bikes which use a large volume tire that is approximately
27.5 inches in diameter, 56 mm wide (ISO 56-584 / 27.5 x 2.25) on an ISO 584 mm rim
.
Will a 26 tire fit a 27.5 rim?
Most 26-inch frames have enough room to accept a 27.5-inch wheel as long as the tires aren’t very wide
. To know with certainty, it’s best to use a 27.5-inch wheel equipped with the tire that you want (or a model with a similar width) as a reference. You can borrow a wheel from a friend or go to a bike repair shop.

What size wheels do pro cyclists use?
