Product details

Protect your tailbone with the Alpinestars Nucleon KR-TB, a lightweight extension designed to shield the vulnerable coccyx area during rides. This innovative protector seamlessly attaches to existing Alpinestars back armor systems (KR-1, KR-R, and KR-2 models), adding targeted defense without bulk or complexity. The sleek black and white design integrates smoothly with your protective gear while maintaining comfort and mobility.

Whether you're commuting through city streets, enjoying weekend cruises, or pushing harder on the track, additional tailbone protection gives you confidence knowing your spine is comprehensively safeguarded. This protector is ideal for riders who want enhanced coverage from quality protection that doesn't compromise on wearability or fit.

Solid steps show periods confirmed by the store’s change-only price history and completed crawl record: if the price had changed at a check, another point would appear. Dashed steps show overdue periods with no completed crawl confirmation. Every line stops at that listing’s last confirmed check and is never extended to today. Prices are not live and may have changed since the last point shown.
