V-Brake 

Loosen the clamp that holds the brake cable with an Allen key if necessary. 

Hold each arm in towards the rim of the wheel and pull the loose brake cable through the clamp. 

Lock the nut into the position. 

Once you have pulled the cable tight, use an Allen key to tighten the clamp. This will hold the cable in 
place.  

Make sure that the bolt is tightly holding the brake cable before you ride!

the twin fork blade mounts, using both a 

small and large washer centre the guard and, tighten from the hex key end. 

During tightening, recheck for centring and possibly raise or lower the guard.
