To start your journey and order your new bike with Vires Velo, follow the steps below or just contact our team now to get started.

  1. Build your bike spec using our online bike builder here
  2. Secure your build by placing a £500 deposit (fully refundable)
  3. Our build team will contact you to confirm your options
  4. Your final balance will be due 1-2 weeks prior to your bike being built by the workshop
  5. Your new bike will be delivered or can be collected

If you require a bike fit with us, this can be booked here. Once your bike fit is complete we will use your data to determine your spec and final set-up.

Your new bike options:

  • Built by Vires Velo in the UK to your exact spec
  • Choose between Black Inc’s FORTY-FIVE or SIXTY Wheelset
  • Choose from 12-Speed Shimano Dura-Ace / Ultegra Di2 or SRAM Red / Force AXS
  • Choose a Black Inc Integrated Barstem in your size
  • Choose an Inline / Zero Seatpost or 25mm Offset
  • Delivery or collection available

They call the OSTRO an ‘everything’ bike and we agree. It’s light, smooth and aero, so it’s ready for dream trips to the mountains or to the cobbled Classics, for long weekend rides or fast-paced chaingangs, and it especially loves to be raced. It can take tyres up to 32mm, so it’s ready for Britain’s rougher tarmac.

  • Electronic shifting only: to save weight and aero drag, and in line with customer wishes, the OSTRO is built for electronic groupsets only
  • T47 bottom bracket: thread-fit BB standard gives a secure fit and makes maintenance easier
  • Three fork offsets: ensuring every customer enjoys optimised handling characteristics, the OSTRO uses three different fork offsets across the size range compared to the industry standard of two
  • OSTRO seatpost: the mid-depth aero profile and lightweight seatpost is offered with a choice of 0 or 25mm setback
  • Cockpit choice: the OSTRO is compatible with the one-piece Black Inc Barstem as well as conventional separate bars and stems. When using separate components, the cables enter the frame below the stem
  • Factor standard geometry: the handling and fit geometry of the OSTRO are both near identical to the O2 and O2 VAM, which makes it easy for the pros to switch between models and eliminates that issue when you’re choosing which Factor to buy

We will even set up and mark your saddle height so you can ensure your new bike is set up and ready to ride.
