The Firewire Groove 5-Fin Set Medium/Large is Rob Machado's throwback high-performance fin — a pivot-inspired thruster designed specifically for the Groove model's performance-focused rocker and outline, with a progressive flex that delivers spring and liveliness out of every turn.

Template: Upright (pivot) template with Rob Machado's hybrid DNA — a lengthened base that adds drive while retaining the quick-turning response of a pivot fin. Designed for punchy, hollow waves and committed vertical surfing.

Construction: Rob worked directly with Firewire's fin team on the layup — varying carbon layers over a bamboo core create a progressive flex where the leading edge is stiffer (for immediate response and drive on entry) and the trailing edge flexes more (for spring and liveliness on exit). The result is a fin that accelerates you out of turns rather than just pivoting through them.

Performance: Lively and responsive in waves from waist-high to overhead where the Groove's performance characteristics are most at home. Works best when you want speed through turns and that characteristic snap out of the pocket that Rob's surfing is built on.

Compatibility: Single Tab variants compatible with Futures fin system. Sold as a 5-fin set (thruster + quad rears). Medium/Large size — suitable for most adult surfers 150–185 lbs.
