The spacing of a frame/fork is measured from the inside surfaces of the dropouts, where they come into contact with the locknuts of the wheel’s axle. Halo Dropout spacing. The hub spacing is measured from the outside face of the lock nuts (or equivalent), this is commonly called the “O.L.D.” (Over-Lock-nut Dimension)
Do you know all the parts of a bicycle?
Composed of a top tube, head tube, down tube, bottom bracket shell, seat tube, seat stays, and chain stays (see image). … Headset – the collection of bearings housed within the head tube of the bike frame; it provides smooth steering. Hub – the central component of a wheel; inside the hub are the axle and ball bearings.
How do I know what size my bike hub is?
Here’s how to measure these distances:
- Figure out the distance between the lock nuts (where the hub sits in the dropouts) – 100 or 110 mm is typical for the front. …

What part of a bike is the crank?
Cranks are levers that connect the pedals to the bottom bracket spindle. The cranks are fitted with toothed sprockets called chainrings that drive the chain. Cranks may be removed to replace cranks or chainrings, service the bottom bracket bearings, or to clean the chainrings.
What is the inside of a bike tire called?
The common bicycle tire is called a “clincher” tire, and in made with bead on the inside edge of the tire. The bead fits snugly into the wheel rim. As the inner tube is inflated, the tire bead is pushed against the “bead seat” of the rim, the portion of the rim that is hooked to hold the bead.
Do bike hubs make a difference?
Hubs that are “louder” usually have more engagement points. This means your drivetrain picks up faster, so less energy is lost. Hubs that have sealed cartridge bearings or needle bearings usually never need to be replaced, they’re far stronger and stay cleaner.
How do you spread bike forks?
Thread the nuts onto the rod, put the washers on the outside of the nuts and adjust the distance between them until the washers will just fit inside the fork dropouts. Back out one of the nuts slowly to spread the fork blades. Stop often and check your progress. Continue until the new hub will just fit.
What is hub old?
Most cartridge-bearing type hubs don’t have locknuts, so the spacing is measured from the equivalent shoulder surface of the axle ends.) The spacing dimension is commonly referred to as the “O.L.D.” (Over-Lock-nut Distance) This hub has an O.L.D. of 135 mm.
What is FD in bike?
FD stands for Front Derailleur (bike part)
What is known as the cockpit of the bike?
#17 • Oct 10, 2010. I always assumed the “cockpit” referred to the area between the saddle and the bars where the rider is located when controlling the bike and was meant to connote the space/distance and not so much the actually components involved.

However shorter chainstays make the bike a little bit more playful and more maneuverable in tighter corners. Shorter stays would also make manuals and wheelies easier as your weight is naturally farther back on the bike.
What is the difference between a cross bike and a gravel bike?
The principal difference between a cyclocross bike and a gravel bike is found in their respective geometries. … A cyclocross bike will also have shorter chainstays and a lower stack height, both of which combine for a more aggressive riding position and significantly more agile handling than a gravel bike.
What is a bicycle seat stay?
The seat stay connects the seat tube to the rear dropout. Most bike frames use two parallel tubes that connect above the rear wheel. This is also the spot on the frame where the rear brake caliper is attached.
