Shimano's new SPD-SLR comes with a brand new cleat design – but why?
The SPD-SLR ecosystem aims to improve power transfer and stability while reducing weight
Shimano has introduced a new SPD-SLR cleat system that replaces SPD-SL, marking the first update to the road cleat design since its initial release in 2003. This new system is set to be integrated with top-of-the-range shoes and pedals, aiming to improve power transfer and bike control. The SPD-SLR cleats boast a lower stack height, faster engagement, lighter components, and simplified fit adjustments.
By reducing the stack height by 2.3mm, Shimano claims athletes can gain a 1% increase in power for every millimeter, enhancing overall performance. The new cleats are also 22% lighter than their SPD-SL counterparts, and they offer a wider catch zone and a narrower engagement angle, allowing riders to clip in more quickly and securely.
The SPD-SLR cleats are available in three float options and are priced at £24.99/€28.99 per pair. Despite the introduction of SPD-SLR, Shimano will continue to support the SPD-SL system, ensuring long-term availability for existing users.
