GENERAL PRE-RIDE CHECK

8

• Check the connection between the 

handlebars and stem. Try pushing the 

handlebars up and down - there should 

be no movement between these two 

elements. If there is any, it is necessary 

to tighten the stem bolts (shown above). 

• Check the headset for play (stand 

next to the bicycle, apply the front brake 

and push forwards and backwards. 

There should be no play between the 

frame and fork). If any play is found 

contact your local bike shop or If you 

are a confident mechanic then adjust 

this yourself.  Follow these steps: 

Loosen the steer clamp binder bolts. 

Adjust preload until no binding or 

looseness are present in the headset. 

(Shown above) Align the stem with the 

front wheel and now tighten the steer 

clamp binder bolts alternately, in small 

increments. Once again, check for 

headset play. If play exists, loosen the 

steer clamp, pinch bolts, and tighten 

the top cap anchor bolt 1/16th of a turn. 

Align the stem, and retighten the pinch 

bolts Remember to tighten both bolts 

alternately. Repeat until proper adjust-

ment made. All parts of the stem should 

be regularly checked for damage or 

cracks. If you find anything suspicious, 

contact an experienced bike mechanic 

immediately. A defective steering sys-

tem can cause serious injury or death. 

• Check if the wheels are straight (lift 

the bike and spin each wheel - the rim 

should not move more than around 

1 mm to each side). Check if all the 

spokes are tight by running your hand 

around each wheel on both sides. 

Contact your bicycle dealer to resolve 

any problems. Do not attempt to ride a 

bicycle with wheels that are not straight 

or with spokes that are loose, as it is a 

danger to your health and life.

• Check if the tyres are properly inflated 

(see the prints on the side walls for in-

structions about the optimum pressure: 

usually 30 – 50 psi depending on terrain 

and weather conditions). Use a proper 

bicycle pump with a pressure gauge to 

achieve the correct pressure. 

• Check the overall conditions of the 

tyres, if they are damaged, torn or worn 

out you should replace them before 

riding. Using worn or damaged tyres is 

dangerous to your health and life. Make 

sure tyres are correctly inflated and are 

in good shape. Spin each wheel slowly 

and look for cuts in the tread and side-

wall. Replace damaged tyres before 

riding the bike. 

• Proper fork maintenance is essential 

for long life and optimal fork function. 

Lack of maintenance may result in 

faster wear and may lead to malfunction 

causing serious injury or death. If you 

are not sure how to maintain the fork, 

you should consult your dealer to help 

you with your maintenance require-

ments. 

• Do not ride if any defects are noticed! 

• For information about servicing sus-

pension forks mounted on the bike it is 

necessary to follow the manufacturer’s 

instructions closely. The user manual 

for the suspension forks is supplied in 

the box with every bicycle and at the 

end of this manual.   

• Check wheel axle to fork connection 

- this is critical for your safety. If you 

have axle nuts they should be tightened 

according to the wheel manufacturer’s 

specification.
