Stans Notubes Flow S2 E-Sync Hub + Flow S2 Rim

The e-bike, trail, all-mountain, enduro and DH wheelsets from NoTubes featuring E-Sync S hubs and sturdy 33 mm wide asymmetrical Flow S2 rims with a 30 mm rim width for tyres up to 2.6 inches wide.

Stans Notubes E-Sync Boost Hubs

The extra-robust E-Sync S hubs from Stans Notubes, approved for e-bike use. Naturally, the wheelsets are also ideal for trail and enduro use. The E-Sync hubs, designed to handle the higher torque and loads of e-bikes, feature a quick 8.18-tooth engagement and can withstand 47 per cent higher torque loads than previous Neo hubs. Heavy-duty chromoly axles and bearings from Enduro-Bearings, including a double-row freehub bearing. The reinforced hub design distributes the load away from the bearings. The E-Sync end caps and freehub bodies are compatible with earlier Neo hubs.

Stan’s Notubes Flow S2 rim:

The S2 rims are made from 6061 aluminium with a durable sleeve joint at the rim joint and stainless steel rim eyelets. They are based on Stan’s proven conventional symmetrical Bead Socket Technology for easy inflation.

Experience gained from successful World Cup DH use, combined with the wide 30 mm Stans WideRide rim width, results in outstanding tyre stability when cornering hard at virtually any speed. With the WideRight System introduced by Stans NoTubes, the rim width increases to 30 millimetres – for even better tyre support and full volume development. Inspired by Stans carbon rims, the new rim profile, combined with the new 6069 aluminium alloy, increases lateral stiffness and impact resistance whilst reducing the risk of snake bites.

The Stans NoTubes rims are perfectly designed, thanks to special rim flanges for fitting tubeless tyres. Thanks to the wide rim bed, the tyre is guided superbly and offers the best rolling resistance.

Rear hub Boost QR 12x148mm standard:

This new thru-axle standard requires new hubs. Only compatible with rear ends with a 12x148 mm mounting dimension. The wider hub shell with the flanges positioned further out allows for wheelsets with greater lateral stiffness. On Boost hubs, the brake disc mount is also positioned further out. Boost hubs can only be used with a 148 mm mounting dimension.

Notubes BST

Notubes’ Bead Socket Technology. This special rim design features a wide rim bed with a low flange for high tyre stability and full tyre volume development. The BST technology helps retain air better in tubeless systems, resulting in less rotating mass and a virtually increased effective rim width compared to competitors. A wide rim also reduces tyre flex in corners and allows the bike to be ridden with lower tyre pressure. The 2" rim is fully tubeless-compatible when used with rim tape and a valve.

Stan Notube spokes:

The black stainless steel spokes used by Stan’s are highly durable and allow for easy repair or replacement should the need arise.
