Changing the tube (Fig. D)

1.  Let the air out of the tube.
2.  Using the flat end of the tyre lever (7), careful-

ly push it between the rim and the tyre. Start 
near the valve.

Note:

 To prevent the tyre lever falling out 

again, you can attach it to a spoke using the 
hook.
3.  Insert the second tyre lever (7) in a little 

further and pull the tyre over the rim until the 
tube can be removed all the way around.

Note:

 Handle the tyre lever carefully. The tube 

must not be damaged.

Removing a (square) crank (Fig. F)

1.  Loosen the crank bolt with a suitable key and 

remove it. 

Note:

 Some cranks have bolt covers. These 

must be removed before the crank is disassem-
bled.
2.  Turn the bolt of the crank puller (10) back 

completely and turn the crank puller (10) by 
hand into the crank. 

Note: 

To make sure that the crank puller is firm-

ly seated in the crank, tighten it with a spanner 
(SW 22mm).
3.  Screw in the bolt of the crank puller (10) with 

a spanner (SW 14) until the crank has come 
loose. 

Removing (Hollowtech II) crank 

(Fig. G)

1.  Unscrew the crank cap with the star cap tool 

(11).

2.  Loosen the crank bolts with the appropriate 

Allen key (6).

Removing the inside bearing  

(Hollowtech II chainset) (Fig. H)

1.  First remove the crank. 
2.  Loosen the left bearing shell with the bearing 

spanner (2), turning anti-clockwise.

3.  Loosen the right bearing shell with the bearing 

spanner (2), turning clockwise.

4.  Remove the inside bearing. 

Note: 

Grease the inside bearing before rein-

stating.

Tensioning the spokes (Fig. I)

1.  Attach the spoke spanner (9) to a nipple.
2.  Turn the spoke spanner clockwise to tighten 

the spoke or anti-clockwise to loosen it.

3.  Check the tension of the spokes and repeat 

steps 1 and 2 if necessary.

Opening the chain (Fig. J) (Fig. K)

1.  Put the chain rivet tool (8) onto the lower 

chain strand.

2. Place the chain exactly onto the guide rail 

(8e).

3. Turn the adjusting screw (8a) to secure the 

chain. The chain guard (8b) must be correctly 
aligned with the chain and be firmly attached 
to the chain. 

Note:

 The chain guard holds the chain tight 

during removal / insertion of the chain rivet and 
prevents the chain from tilting. The hollow space 
serves to receive the chain rivet when it’s being 
pressed out. 
4. Turn the lever clockwise to remove the respec-

tive chain rivet using the chain tool (8c). 

5. Pull the rivet-free end of the chain out through 

the rear derailleur.

Note: 

Note that the guide rail (8d) is not suit-

able for holding the chain. Always put the chain 
onto the guide rail (8e) when pressing the chain 
rivet in or out.

Closing the chain (Fig. K)

1.  Insert the two ends of the chain into each oth-

er and fit the chain into the chain rivet tool (8).

2.  Secure the chain with the chain guard (8b).
3.  Position the new chain rivet on the guide rail 

(8d) and press it in.
