The Jingtan 4.0 SL is BMAI's lightweight race trainer: no carbon, but still a fast, springy carbon-free trainer feel, with a three-section widened base and flat TPU midfoot plate for stability and anti-torsion. The ride is soft and highly adaptable, easier to handle than a carbon racer — great for runners building capability through high-mileage speed work, and a smooth step-up for newer runners.

Resumo das avaliações
The BMAI Jingtan 4.0 SL (2026) is a lightweight race trainer BMAI independently developed for high-mileage training, not an iteration of a previous model. It shares the same Evonik nylon-billet supercritical foam as the Jingtan 4.0 with the same 31mm forefoot / 35.5mm heel stack and 4.5mm drop, but the key difference is the plate: the 4.0 SL has no carbon, only a flat TPU midfoot stabilizer for support and anti-torsion with little extra propulsion, so it feels genuinely comfortable even at slower paces. The three-section widened base — forefoot, midfoot and heel — secures anti-rollover performance in fast turnarounds and corners, making it more stable than the carbon version. The midsole tune emphasises resistance to compression, fatigue and foam crumbling, aimed at high-mileage, high-frequency speed training; at about 195g (EUR41) it runs roughly 20g heavier than the 4.0. It keeps the kite-gauze upper, integrated knit sock tongue, wheat-lacing anti-slip laces and heel memory-foam pillow, with a PU polyurethane starburst outsole for excellent wet grip. Positioned as a lightweight race trainer for advanced runners building a base through mileage and speed work.
