Factor OSTRO Gravel – Size 58 – Dura-Ace Di2 with Power Meter

For sale is my Factor OSTRO Gravel in size 58. The bike was purchased new from Sportster24 at the end of August 2025.

It is approximately one year old, has covered fewer than 1,000 km and is in excellent condition. This is a very fast and lightweight premium gravel bike, combining the responsiveness of a high-end racing bike with excellent off-road capability.
