Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!


With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

  • Question asked by Hazel on May 22 2021 2:10PM
    Q: What should the tyres be pump too ?
    A: Bontrager recommend that on the Bontrager GR1 Expert they run at a maximum pressure of 50psi.
  • How do you fit bar ends to this bike?
    Question asked by Simon on Apr 5 2021 8:05PM
    This bike is supplied with 'lock-on' bar grips. To remove/adjust the the existing grips an allen key bolt is loosened and the grips can be moved. The end cap will need to be removed also to acconmate the bar ends. I would suggest the addition of theese Ergon grips to still provide the support of the existing gribs with the aditional benefits of bar ends.
