I bought Orbea Oiz H20 in XL frame, which turned out to be of poor quality with significant issues arising from the start. Wheels failed on my first ride - half of the spokes on the rear wheel became undone, suggesting poor assembly and/or no safety checks by Sigma Sports. The bottom bracket and the rear shock retaining bolt failed after a few months of gravel riding and commuting. My Orbea Oiz H20 was out of order for weeks while the warranty jobs were carried out. No replacement bike during repairs or compensation offered for lost time, petrol on multiple trips to and from the store - all because of the inadequate product sold by Sigma Sports! The Orbea Oiz H20 has the worst quality of paintwork I have ever seen on a bike, with chips on a frame showing after regular commuting rides along the river. The skinny paint layers without much coating result in white spots on dropouts and the main frame. I splashed close to £3000 and received a poor product that lasted only 16 months and average customer service. In the end, I collided with a rather condescending attitude from Sigma Aftercare, feeling hopeless and out of pocket. Their motto should be Sigma - Customer Service Enigma! I recommend buying a better bike from somewhere else and from people with customer care at the heart of their business! This was my last purchase with Sigma Sports.
