NS Bike’s Eccentric Alu EVO 27.5 Frame is perfect for those who like to go full gas on the trails. Tough, aggressive and super-versatile, its AL6061-T6 alloy frame is butted and custom formed to be strong and overbuilt, yet it’s still lightweight and highly responsive. The frame also has cable routing for a dropper seatpost and is compatible with up to 150mm travel forks.
If cromoly is not on your list of priorities, this frame offers the same concept as the Eccentric at a much lower price. The aluminium frame is strong and overbuilt, but at the same time light and responsive. It will be a perfect platform for building an aggressive 650B trail bike.**Recommended fork travel:** 130-150mm**Head tube:** integrated tapered IS42/IS52**Fits forks:** standard 1-1/8 or tapered 1.5 1-1/8 steerer tubes**Head tube length:** S size: 105mm, M size: 115mm, L: 125mm**BB:** threaded 73mm (w/o ISCG mounts)**Biggest chainring:** up to ~34t (SRAM XX1 up to 32t)**Seat post/seat clamp:** 30.9 / 34.9**Cable routing:** stealth cable route in seat tube for dropper post**Maximum recommended tire size:** 2.35**Disc brake:** post mount disc brake mount, max rotor size: up to 185mm**Hub spacing:** hub spacing 142x12mm, NS axle included**Sizes:** 3 frame sizes (16, 17.5 19.5)**Weight:** ~2.2kg (M size)See more at: [**NS Bikes**](http://www.nsbikes.com/)
