NS Bikes Eccentric Alu EVO 27.5 Frame

The Eccentric Alu EVO 27.5 Frame from NS Bikes is engineered from strong and lightweight custom-formed aluminium tubes that features Boost 148x12mm rear dropout spacing, internal dropper-post routing and modern enduro-inspired geometry. Also, it's ideal for use with 130-150mm travel suspension forks and has max tyre clearance of 27.5x2.4". This frame is suited to enduro trail riding, bike park sessions and all-mountain epics.

Modern Geometry, Long Ready and Slack Head Angle

Radical, modern geometry with a very long reach and a super slack head angle make this bike ideal for anyone who likes to go full gas! 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 27.5 trail bike. Fitted with a good 140mm fork and dropper post, the Eccentric will fly across trails and put the kind of smile on your face that only a hardtail can deliver. And, it features a Boost 148 rear thru-axle for greater trail stability.
