Excellent service from Sigma Sports, especially Alex at the Letchworth store. He was fantastic throughout the whole ordering process—always quick to reply, never rushed, and incredibly helpful. His recommendation to have a final fit before collecting my frame was spot on. He explained everything clearly and took great care dialing in my fit. When we set it up on the test bike, it was perfect straight away—no tweaks needed. Nailed it. Huge thanks to Alex and the Sigma Sports team. Highly recommended.
