Stans No Tubes Flow S1 Mountain Bike WheelsetDurable and light, the Stan's No Tubes Flow S1 Mountain Bike Wheelset is ready to handle the toughest trails. Multiple World Cup Downhill (DH) winners have inspired the race-ready design of the Flow S1 wheelset making it the ideal addition to any keen rider looking to tackle challenging trails and reach the podium. Strong and Multi-purposeFeaturing reinforced rim walls with a 1.6mm deeper profile, the Flow S1’s offer greater impact strength for an even wider range of use. Despite this, they only have a minor weight increase over Stan’s other models. They’re constructed with a 32-hole spoke count front and rear, using easily replaceable standard spokes. Combined with Stan’s faster-engaging and CNC-machined Neo hubs, this wheelset is the ideal choice whether you ride trail, all-mountain, or enduro.Features: Durable and lightweight aluminium construction Wider rim width for more stability with larger tyres 3mm wider than Rapid 30 with no weight gain Developed on the World Cup DH circuit Rim profile optimised for 2.35" - 2.80” tyres Rim Internal Width: 29mm Rim External Width: 33.1mm Rim Depth: 17.6mm ERD: 566mm (27.5") / 604mm (29") Spokes: Sapim 2.0/1.8/2.0mm ETRTO: 584x29 (27.5") / 622x29 (29") Nipples: Secure Lock brass silver nipples ISO: 27.5"x33.1mm / 29"x33.1mm Hub: Stan’s Neo Tape: 30mm Hole Count: 32-hole, 32-hole Valve: 35mm Presta Rim Material: 6061 Alloy Max Spoke Tension: 125kgf (1225N) Max Rider Weight: 114kg (250lbs) Max Pressure with 2.4" Tyre: 37psi Max Pressure with 2.80" Tyre: 26psi Brakes: Disc Freehub Body: Neo Durasync Red Tubeless tape pre-installed Use: Aggressive Trail, All Mountain, Enduro, and Downhill Weight: 2034g (27.5”) / 2134g (29”)Technologies: WideRight: Rims that are too narrow fail to offer sufficient sidewall support and protection to your tyres and create a less stable shape. The result is less control in the corners, less traction on climbs, and more rolling resistance. Rims that are too wide also distort the tyre profile, decreasing traction and control and driving impacts directly into the rim, negating the impact absorbing advantages of a tyre's volume. Stan's WideRight rim widths are designed to strike the perfect balance between tyre volume and sidewall function. BST (Bead Socket Technology): Bead Socket Technology rims are designed to match the shape of your tyre's bead to create a safer and more secure airtight interface. BST rims secure the bead of the tyre, not the sidewall, creating an airtight seal while allowing the tyre's sidewall to expand to its true, rounder, more effective profile. The result is more traction and less rolling resistance. With lower-profile, less vulnerable sidewalls, Stan's BST rims are also lighter and stronger by design and accelerate more quickly.
