Fitbikeco’s PRK bikes feature frames with lower stand-overs, short chain-stays and a middle of the road 75.3 head angle that’s maneuverable but stable when blasting transitions. PRK forks are responsive with 25mm offset drops and feature a longer 172mm steerer tube for use with a GYRO. Slightly lower 8.7” bars match perfectly with the taller GYRO stack height and top load forged FIT stem. Other notable features on 2023 PRK’s include smaller 160mm cranks on the 20” TT, and slightly longer 165mm cranks on the 20.5” TT.Frame: 20.25” tt (small), 20.5” tt (medium), 20.75” tt (large) cro-mo top and down tubes - Geometry: series one Headset: a-headset - Bb: sealed mid - Stem: fit top load - Grips: fit crossfit - Seat: new more padded integrated combo - Cranks: tubular cro-mo 160mm - Sprocket: fit key 25t - Pedals: fit pc - Front wheel: fit s1w w/unsealed hub - Rear wheel: fit s1w w/sealed 9t cassette - Tires: fit oem 2.4”Brakes: new u-brake w/more tire clearance & softer pull springs - Weight: 11.79 kg - Weight: 12.29 kg
