Once you’ve place your order, we will contact you to discuss your frame colour choices and any changes you may want to make to the specification. We will require your child’s Age (birthday), Height, Inside Leg & Shoulder Width for correct component selection.
If you intend to Road Race or Triathlon (on gear restricted events) let us know your child’s British Cycling/British Triathlon age category and we will specify the correct chainring, cassette & tyres to maximise the available gearing.
We are happy to delete parts if you wish to use your existing components. Many more options are available, please contact us to discuss. Sometimes, small changes are made to the spec due to parts availability – if this is the case we always contact you first (we can also fit SRAM eTap groupsets to the Scatto J-Cross 26 and 28 models, plus more).
