This is a wheel size with smaller rims than the 700c road bike standard, but larger than the 26 inch size that was the standard for mountain bikes until a few years ago. Because the rims are smaller, fitting 650B wheels into road and gravel bikes that usually take 700C wheels allows the use of fatter tyres with little or no alteration to the frame design, assuming you have disc brakes.


Wheel size designations are a proper omnishambles. The only way to be sure a tyre will fit a particular rim is to look at the size of the bead seat, the part of the rim where the tyre fits when inflated. Your 700c wheels have a bead seat diameter of 622mm; for 650B it's 584mm.


650B is no longer just on mountain bikes. Road bike manufacturers from small independent frame builders like Cannondale have adopted it for all-purpose and gravel bikes.


The combination of a 650B wheel's 584mm rim and a tyre width of between 30 and 50mm gives about the same overall wheel size as a regular 700c rim and 25mm tyre, so the rolling speed and handling characteristics will be similar to a regular road bike.

MTB Rims Buying Guide


The type of rim you choose must be matched to the type of riding you do – a lightweight set of XC racing hoops simply can’t withstand the beating dished out by a boulder-strewn descent, while a super-strong pair of DH rims is hard work to pedal for any length of time.


Lighter rims mean less rotational weight, which translates into improved acceleration and easier speed – perfect for fast cross-country riding and racing. However wheels for certain MTB disciplines – particularly downhill racing (DH), Enduro riding Freeride (FR) require wider, stronger rims, which can take sustained punishment without folding like a taco (not good).


The three most important considerations when choosing an MTB rim are diameter, width and number of spokes.



The three most common MTB rim diameters are 26”, 27.5” (sometimes referred to as 650b) and 29” (see our ‘Wheels’ buying guide for an-depth explanation as to the differences between the three and the history of the standards).


Whichever rim diameter you opt for will be determined by your bike type (you can’t put 27.5” rims on a bike made for 26” wheels, for example), which in turn will depend on the type of riding you intend to do and your personal preference in wheel sizes.


Finally, some specialised disciplines – Dirt Jumping (DJ) and Street – opt to use smaller, 24” wheels so you may need rims to suit.



Narrow, lightweight rims are used for XC, marathon and general off-road riding, and tough, wider rims for more gravity-orientated adventure.


In recent years 23mm has become accepted as a standard rim width for XC and trail riding, usually matched with tyres up to 2.1” in width. More extreme AM or Enduro riders who aim to tackle rock gardens and technical terrain lean towards rims of 28mm in width, with the ability to comfortably take large-volume 2.25” to 2.4” tyres. Meanwhile DH and FR riders who put their wheels through serious punishment in the air and on the race course may choose rims of 36-40mm or even more, with the capability of using heavy, reinforced 2.5”-2.7” DH tyres.


NOTE: Remember that if you are choosing new wheels for a bike equipped with non-disc brakes you must make sure that the rims have a braking surface for the pads to make contact with. Rims without this should be marked as ‘disc’ or ‘disc only’.


Spoke number

The more spokes a wheel has, the more the load is spread and the stronger the wheel should be, while less spokes means a lighter wheel.


For general trail riding 32-spoke rims have become the accepted standard, with more lightweight race wheels featuring 28- or 24-hole drilling. More extreme riding styles call for more strength so 36 spokes are common in AM, Enduro, DH and FR wheelsets, while the most demanding jump and street riders may opt for anything up to 48 spokes in order to handle the impacts dished out by tarmac and concrete.

When buying replacement rims for an existing wheelset or when building a new wheelset from parts, be sure to match the number of spoke holes on the rim with the number on the hub – e.g. a 32-hole rim needs a 32-hole hub, etc.


NOTE: Building, lacing and truing (adjusting spoke tension so the wheel runs perfectly straight) wheels is an art in itself that demands experience, time and patience – something best left to the professionals if you are not confident. A new set of wheels may naturally go ‘out of true’ after a couple of weeks of riding and need to be adjusted – there are plenty of resources in print or online that will demonstrate how to do this, or your local bike mechanic can easily do it for you.


Finally, you can also buy MTB rims that are either ‘tubeless’ (conform to the Universal Tubeless Standard or UST) specifications or ‘tubeless-ready’. The former are designed to be run with UST tubeless tyres while the latter have special features (adapted hooks for tyre beads, shallow-drop centre sections) optimizing them for tubeless use with the aid of a tubeless conversion kit.
