Road Bike Wheel Size In Mm

However on a mountain bike the answer is yes.

Road bike wheel size in mm. Mountains bikes now come in three different wheel sizes. Bike frames are measured from. Rear wheels generally need either standard 135mm spacing and qr axles or 142x12 bolt through. The standard modern road bike wheel has an iso diameter of 622 mm and is referred to as 700c makes sense right.

Fortunately most wheels can accommodate a range of axle standards. So in this example it would be 28 x 2 622 3 1415 2130. Subtract 6mm from overall width to estimate the rim section or simply measure the distance between the flanges. Some downhill frames may have 150mm rear spacing.

This wheel size is the largest available for conventional bicycles giving a racing bike more stability at high speeds. This is approximate and rarely matches. You can find them with 26 wheels 27 5 wheels or 29 wheels.

Racing bikes use the 700c size which has a tire bead set diameter of 622 millimeters. Forks will usually be 9mm quick release qr 15mm or 20mm bolt through. On road bikes and hybrids no as these bikes will all have a similarly sized wheel. Most thru axles are found on mountain bikes although increasingly disc braked cyclocross and road bikes are using them.

622 17 for the size usually fitted to touring and hybrid bikes. Some rims are also now marked according to iso with their bead diameter and internal section width where the tyre fits. These bikes are also generally specified with tires that are 25c or 25mm wide on their outside before inflation. Today when off road bicycles with wheels larger than standard mtb wheels started to be popular it s wheels are marketed as 29 but in fact are 622 wheels with wider tyres so that outer diameter is close to 29.

Diameters for front thru axles include 20 mm 15 mm 12 mm and 9 mm. Standard road bicycle wheel size today is 622 mm and it usually takes tyres of 23 622 or wider 25 622. If the rim is not marked with its bead diameter you can read this from the tyre it s the one dimension they have in common. A iso tire size of 28 622 which of course is backwards b c it s european from how we would refer to a 700 x 28c tire has a tire width of 28 mm and a rim diameter of 622 mm.

But some manufacturers give the overall width instead. To get the approximate diameter of the wheel with the tire on you would take the diameter of tire x 2 because it s both on the top and bottom the diameter at the rim pi 3 14 to get the cimcuference. Most new road bikes with rim brakes come with wheels that are designated 17c or are 17mm wide between the tire bead hooks that run along the inside of each rim.
