Mountain Bike Wheel Small Parts

Match the axle diameter and hub spacing to your frame: common options are 12mm or 15mm thru-axles with rear spacings like 142mm or 148mm and a 100mm front. If you need extra stiffness for disc setups, a 15mm thru-axle such as the Trifox ATS100 pairs well with compatible end cap kits to avoid swapping the whole hub.

Hookless rims labeled tubeless-ready can work very well when paired with tubeless-specific tires and proper sealant, reducing flats on rough trails. Aim for a rim inner width between 25–35mm to match your tire size, and remember lighter carbon options like Elite Wheels at 380g trade some compliance for added stiffness.

Higher-engagement freehubs reduce play and improve pedal responsiveness, with many high-engagement units offering 10–18 degrees of engagement. For aggressive riding, prioritize a rear hub and freehub body that handle drivetrain forces well to keep power transfer quick and reliable.

More spokes—28 to 32 is common—generally increase wheel strength and help maintain tension balance for rough-terrain durability. Pairing that spoke count with a 25–35mm rim inner width improves traction and you can opt for steel spokes for impact resistance or a carbon rim for extra stiffness.

Sealed cartridge bearings provide smooth rotation and lower day-to-day maintenance while offering load ratings in the 100–200kg range for trail use. Hubs like the Trifox M827 use low-friction sealed bearings suited to rough terrain, though sealed units are usually replaced as assemblies if they wear.
