- Loosen the adjuster until the wheel just spins freely.
- Tighten the locknut. Note: During the first few miles brake linings "bed-in" and may require adjustment.
The Sturmey-Archer SPRINTER Hub can be fitted into rear chainstay widths between 120 mm - 126 mm using the appropriate spacers.Note: These products are not designed for bicycles with vertical rear dropouts as chain tensioning cannot be achieved. (But on the other hand, see this -- John Allen) If the wheel is removed, these instructions should be followed during re-assembly:-
- With the chain on the sprocket place the hub axle into the chainstay ends.
- Fit washers and axle nuts. Ensure that the serrations on the anti-rotation lockwashers face into the frame with the lugs located into the chainstay slots. Note: Ensure the correct size anti-rotation washer (to match the chainstay slot width 9.5 mm or 7.9 mm) is fitted. DO NOT tighten the axle nuts at this stage or misalignment of the brake plate may occur.
- Insert brake arm on hub loosely into the clip. With the wheel centralised, chain tensioned and aligned correctly, tighten the axle nuts to a torque of 25NM .
- Tighten the brake arm clip nut firmly to 7NM. Max. Ensuring brake arm remains in line.
- Control Cable - Ensure the indicator (8) is screwed firmly into the axle. Unscrew the indicator by up to half a turn if necessary to ensure easy fitment over the selector guide and connection to the gear cable. Connect the indicator coupling (14) to the gear cable adjuster (12).
- Brake Cable Installation - Pinch Bolt specification:
- Locate the brake adjusting spigot into the slot on the brake arm.
- Set the adjuster so that there is approximately 5 mm. of thread showing above the locknut.
- Holding the brake lever on the brake plate in the 'on' position, pull the inner cable taut, fit the pinch bolt and tighten the pinch bolt screw.
- Cable Installation - Closed End Cables : Locate the brake adjusting spigot in the slot in the brake arm.
- Fit cable nipple into position on the brake lever assembly ensuring that the recess mates with the larger diameter nipple. Note: To maintain maximum braking efficiency avoid sharp bends and kinks in the cable.
- Replace chainguard/gear case (if fitted). Note: Before use check and make necessary adjustments to brakes (See Section 4) and re-adjust gears (See Section 3).
Replace Instruction 2 above by: Fit washers and axle nuts. With the wheel centralised, chain tensioned and aligned correctly, tighten the axle nuts to a torque of 25NM.
Instructions 3, 4 and 7 are not applicable.
When service problems arise, they usually occur outside the hub, and the checks listed previously must be made before removing the wheel from the bicycle.
When service problems occur which cannot be corrected by attention to external maintenance, a close inspection of the working parts inside the hub will be necessary. Refer to the fault diagnosis chart before commencing disassembly which can be done without the use of special tools.
