MAINTENANCE AND UPKEEP

 

Checking and changing worn parts

Regularly check the wear parts of your LT so you do not take risks and 
will not find yourself stuck while travelling. If you have any concerns 
about the wearing of certain components, please consult your Retailer 
or DOUZE Cycles Technical Centre.

Responsible, regular cleaning is essential for a 
reliable bike. Never wait for a problem to get 
worse before acting!

Here is the list of wear parts to be checked regularly and that require 
maintenance at different stages:

 the braking system: pads, discs, brackets, levers and hoses  

 transmission parts: crank-set, sprocket(s), derailleur, chain tensioner, 

chain, and derailleur sheath and cable

 the wheels: plates, radial and lateral rim run out, spoke tension, 

freewheel body and tyres

 the bearings: wheels, steering and chain set
