Compatible with various hub and frames, the new TA5 thru-axle standard targets entry-level volume bikes. The Show Daily editor Laurens van Rooijen reports from Taipei Cycle 2025.
The new TA5 thru-axle system was launched at industry-only events during Taipei Cycle, offering safer handling and compatibility with various hub and frame standards.
There are plenty of good reasons for the use of thru-axles. Safety is key, and the chances of improper use are much smaller with thru-axles than with quick-release axles. As disc brakes make their way into lower price segments, thru-axles are coming in handy to make sure a wheel is properly aligned to avoid brake rub. Still, many entry-level bicycles catering to less experienced riders still rely on quick-release axles.
The novel TA5 thru-axle standard aims to change this, claiming to be a step toward a safer, more universal and user-friendly standard for volume models. This novel axle system relies on closed dropouts, a 5mm steel axle and a lock nut. The integrated derailleur hanger solution simplifies the sourcing of spare parts. Trek and Scott, two major brands have already adapted to TA5 for entry-level bikes. SR Suntour’s new 5TA fork series is directly compatible with the TA5 axle, which requires the signing of a free license to be used.
