Our new FLOW models replace what we used to call TRL models. With the growing trend of dirt riders taking their trail riding to concrete and wood transitions too, we updated the bike accordingly. With stable geometry, chain-stay mounted brakes, longer top tubes (21” and 21.25”), longer cranks and wider bars, these bikes are perfect for larger riders and equally at home going fast in the woods or a concrete bowl. Longer Tech grips with flanges and our alloy Trail pedals work perfectly for all conditions, as do the semi-knobby 2.4 OEM tires which work great on all surfaces including dirt. If you’re looking to go fast and blast, look no further and go with the FLOW.- - - - -FLOW 21″ Top TubeFRAME: Cro-Mo Front TriGEOMETRY: Trail w/74.5° HAHEADSET: Integrated w/Gyro HolesBB: Sealed MidBARS: 2-Piece 8.7” x 29”FORK: 100% Cro-Mo, Tapered Legs, 33mm Offset, Welded InsertSTEM: FIT Top LoadSEAT: FIT Pivotal Seat/200mm PostCRANKS: Tubular Cro-Mo 175mmSPROCKET: FIT Saw 30TPEDALS: FIT Trail AlloyFRONT WHEEL: FIT S1W Rim w/Sealed Hub/Female AxleREAR WHEEL: FIT Double Wall w/Sealed 10T CassetteTIRES: FIT OEM 2.4”BRAKES: U-Brake w/Low Tension Springs, Two Finger Lever, Linear CableMISC: Chain-Stay Brakes
