27.5" / 650B Rear Wheel – Sturmey-Archer S-RC3 3-Speed Coaster Hub, Alex DM18 24.4mm Black Rim
SKU code: BPW-94642
Three gears and a back-pedal brake sealed inside the hub: this 27.5" / 650B rear wheel is built around Sturmey-Archer's S-RC3, the classic choice for a city, cruiser or step-through bike that needs to be low-maintenance.
- Gears and brake are sealed inside the hub, so there's no derailleur to knock or adjust
- Alex DM18 rim, 24.4 mm wide, double-wall, laced 36H
- Silver Mach 1 spokes, hand-laced, tensioned and trued
- Built to order to a standard spec, not machine-laced
The hub. Sturmey-Archer lists the S-RC3 as: classic 3-speed internal gear hub, 177% gear range (steps of 33% and 33%); 6061 aluminium hub shell; takes a 13T to 24T sprocket; hub weight 1290 g.
Fit. It needs a frame with 117 mm rear spacing and takes a nutted axle. The coaster brake needs its brake arm clamped to the frame's chainstay. It shifts with a Sturmey-Archer 3-speed shifter and indicator chain; ask us if you need one. It takes a 13T to 24T Sturmey-Archer sprocket.
Built to order. Hand-built by our wheel builder and dispatched in about 5 days.
