The Shimano HB-TC500-15-B is a dependable Centre Lock front hub built for modern trail and touring bikes running a 15x110mm Boost thru-axle. It pairs a stiff, sealed alloy shell with easy rotor fitment, making it a sound choice for a fresh wheel build or a wheel rebuild.

Highlights

• 15x110mm Boost thru-axle spacing for a stiff, planted front end
• Centre Lock rotor mount for quick, precise rotor installation
• 32 spoke holes suit strong, all-round trail wheel builds
• Sealed cartridge bearings with labyrinth and contact seals for long service life
• Anodised aluminium shell keeps weight in check

Stiff Boost thru-axle front end

The 110mm Boost over-locknut spacing widens the flange stance and works with a 15mm E-Thru axle to deliver a torsionally stiffer, more precise front wheel than an older quick-release setup. The thru-axle itself is not included.

Centre Lock rotor mounting

Shimano's Centre Lock spline interface lets you fit and remove a disc rotor with a single lockring rather than six bolts, saving time and improving alignment and rigidity. A Centre Lock lockring is required and is not supplied with the hub.

Sealed for the long haul

Cartridge bearings sit behind a labyrinth and contact seal system that helps keep water and grit out, so the hub keeps spinning smoothly through wet and dusty rides.
