Wheel dimensions and specifications
Boost vs Non-Boost Hubs: Spacing and Compatibility
Understand the difference between Boost and non-Boost hubs: exact over-locknut dimensions, thru-axle lengths, and what you need for wheel swaps and frame compatibility.
Bicycle Rear Hub Spacing Chart and Standards
Understand bicycle rear hub spacing standards, including OLD dimensions, quick-release vs thru-axle, Boost and Super Boost, and how to choose the right hub for your frame.
Bicycle Hub Cross-Section Anatomy and Rim Depth
Understand bicycle hub cross-sections, rim depth, and tire sidewall markings. Learn how dimensions like width, aspect ratio, and rim diameter affect overall wheel geometry, and how to interpret markings for real-world fitment.
Bicycle Thru-Axle Adapters: Types and Compatibility
Understand bicycle thru-axle adapters: types, hub end caps, axle standards, hub spacing, quick-release conversion, trainer adapters, and compatibility in plain language with measurements and examples.
Bicycle Thru-Axle Sizes and Dimensions by Bike Type
Learn how to read tire sidewall numbers and understand bicycle thru-axle diameters, lengths, thread pitch, and hub spacing for road, gravel, mountain, and fat bikes.
Bicycle Spoke Length Calculator: Hub, Rim and Lacing Dimensions
Learn how to calculate bicycle spoke length accurately. Understand hub flange diameter, flange spacing, effective rim diameter (ERD), cross pattern, and how to use spoke length calculators for MTB, road, BMX, and straight-pull hubs.
Deep-Section vs Shallow-Section Rims: Comparing Rim Depth, Starting with the Tire Sidewall
How to compare deep-section and shallow-section rims, starting with tire sidewall markings such as 28-622 and 700x28C. Covers what rim depth changes and what it does not, with worked diameter and circumference calculations.
Bicycle Rim Types: Construction, Profiles and Differences in Depth and Cross-Section
How to read bicycle tire sidewall numbers, calculate wheel diameter and circumference, and compare rim types by construction, bead profile, braking surface, internal width and depth.
How to Measure Wheel Bolt Pattern: Lug Count and Bolt Circle Diameter
Measure a wheel bolt pattern for 4, 5, 6 and 8 lug wheels in mm or inches with a tape measure, convert patterns like 5x100 and 5x120, and read tire sidewall sizes.
Asymmetric Rim Spoke Offset: What It Means and How to Measure It
What asymmetric rim spoke offset means, how to measure it in millimetres, and how it changes left and right spoke lengths, tension balance and dish. Starts with what the tire sidewall numbers tell you.
