The first time you ride your brand new bike, it's normal that many of its components will move about slightly and settle into their proper places.This is the case of your wheel spokes which you might hear make a "cracking" sound which is naturally due to the residual torsion built up during assembly.Your bike is equipped with sturdy double-walled rims (on the inside of the wheel), so your wheels should be straight and not bent.In the unlikely event a wheel is or becomes slightly bent or twisted, please bring your bike to any Decathlon workshop and they will make the adjustment free of charge, either:1- As part of the free tune-up available within 6 months of the date of purchase of the bike. 2- Covered by the €1 extended repair warranty, if purchased (good for 2 years).
