MAKE IT SHINE! KEEPING YOUR BIKE CLEAN CLEANING OF SHIFTERS Keeping your bike and components clean and correctly lubricated willkeep performance highand usually slow down the wear and tear on parts. We recommend that the internal cleaning and lubrication of shifters should only be done when shifting performance has deteriorated due to excessive contamination. We have found that, generally, the deterioration of shifting efficiency starts with the contamination of the cable and housing system.

SPECTRO 3x7 SPECIFICATIONS 3-speed-hub with 7 speed sprocket cassette Type MH C3721F Spectro 3x7 combines the best of the two gear shifting principles – chain (derailleur) and hub gears – in an intelligent system. Because all 21 speeds are changed on the back wheel the installation of a chain guard on the chain wheel is possible. Gear shifting is performed by means of the ergonomically-designed rotational shifter – Spectro Grip 3x7.

SPECTRO E12 LACING AND INSTALLING HUB Advice: a tool can be used to hold the hub in the vice. This tool threads into the hub’s axle. Tool part No. 00 2324 002 000. • Maximum spoke diameter: 2.0 mm • Please note: Alignment spoke/Nipple The high flanged hub results in a relatively tangential running spoke for three crossed spokes. Some rims do not allow for the flat angle of spoke nipple. This results in an undesirable kink between nipple and spoke (see Fig. 9).
SPECTRO E12 • Bring Clickstick (4) to hub and position the crown (4a) so that red arrow on the hub is visible in the middle of window (4b). By applying a little pressure, snap crown onto hub (Fig. 14). 14 Mounting rear wheel into frame • Place chain (11) on sprocket (2); fit wheel in rear frame; route ends of axle in the grooves of dropouts; adjust wheel in frame, mount axle bolts (10) with washers ribbings point towards the dropouts, and tighten. Use a 15 mm wrench and a torque of 30–40 Nm (266–354 in.

SPECTRO E12 34 14 12 13 35 2 1 • Rotational shifter with a fixed grip (1), turning grip (2), shifter body (3), shifter cable with full cable housing, adjusting barrel (4) and cable clamp assembly (5). • Rotating the turning grip shifts the gears, (2), the selected gear is indicated in the window (6). • It is also possible to shift under moderate pedalling loads • Under high load, the spring inside the Clickstick ‘pre-loads’ for the new gear, allowing the shift only when pedalling force is reduced.
SPECTRO E12 Advice: Locating wedge is used (Ref. No. 2324 001 000 – see Fig. 39) 39 40 1a 1 7 3 4 6 5 41 12 13 • Slowly release cable (this will allow the spring to wind up the cable and rotate the gears from 1 through 12) • Bring Clickstick to hub and position the crown cover (1) over the shifter crown so the red arrows on the hub are visible in the middle of the window (1a). By applying a little pressure, snap crown cover onto hub (Fig. 40).
SPECTRO E12 Rotational shifter/Fixed grips • The rotational shifter consists of three parts (Fig. 45). The shifter body (3) and the fixed grip (1) fit snuggly on handlebar, while the turning grip (2) is fitted into housing only. 3 1 2 Caution: • Fixed grips (left and right) provide an axial safety function. For this reason, they should be mounted in such a way as to make sure they do not slip off handlebar. • Never use lubricants or solvents to install fixed grips. • Never ride without the fixed grips.

SPECTRO P5 • Insert planetary gear carrier, place thrust washer (8) on it and mount retaining washer (7) in recess. Only now should you remove the mounting aid. 14 6 9 8 7 Advice: If the gears are not accurately installed the hub may be tight to move. This could lead to damage to the gearwheels in operation. For lubrication of the hub see “Maintenance/servicing”. 15 1 16 4 3 The assembly of hub types H 5205/H 5225 should be carried out in the same way.
SPECTRO P5 • The Spectro P5 is provide with permanent lubrication and under normal conditions is maintenance-free. If the coaster brake is loaded excessively its effect can be too strong. In such a case the brake shell should be lubricated with a special grease (art. no. 0369 135 100). After dismantling the hub the following items should be carried out: • Oil axle through the axle bore and lightly grease the outside. • Lightly grease the inside teeth on the ring gear – but only oil the pawl pockets.
