CONDITION & SETUP
BRAND NEW - SUPPLIED BOXED READY FOR ASSEMBLY
Your bike will arrive brand new and sealed in its box and will be mostly built with the hard work already carried out in the factory. Once you open the box, fitting of the pedals, stem & handlebars, saddle & seat post, front wheel and front & rear brake cables will be required. We recommend that you carry out a general check over and tighten up of all fixings on pre-assembled parts (wheels, crank etc) once you have completed the build.
We also advise that the brakes will require some adjustment during assembly and again after they have bedded in for a short time. The gears of the bike (if present) may also require minor adjustments during setup and again after your first few rides.
If you are not confident of assembling the bike yourself then we would highly recommend you seek a local professional to complete the setup for you.
