TanTan TT-X71 Bicycle Full Carbon Light Weight Road Bike With WheelTop Wireless Electric Group Set carbon wheels

The reviewer compares the Seraph TT-X71 (also called TTX71) to the Sava A7L Pro, both costing around $1,600. The Seraph TT-X71 features a full carbon frame, carbon wheels, and a WheelTop EDX electronic groupset. The reviewer notes that the Seraph is stiff, fast, and comfortable, but has less stable high-speed handling and a less comfortable stock saddle. It offers electronic shifting that feels premium but is not as refined as Shimano Di2. The bike has 30mm tire clearance and comes with 50mm carbon wheels. The reviewer considers it a good value but notes some drawbacks like a large rear derailleur with bigger gear jumps and a design that resembles the Factor Ostro.

The reviewer tested the TanTan TT-X71 Bicycle Full Carbon Light Weight Road Bike With WheelTop Wireless Electric Group Set carbon wheels and found it to be an exceptional value, praising its full carbon construction, electronic groupset, and carbon wheels for the price. They noted it rides well, is comfortable, and performs impressively, though they mentioned some drawbacks such as high-speed instability and a copied design.

The reviewer discusses the TanTan TT-X71 bicycle, which he has been riding for three to four months and over 800 kilometers. He is impressed with its value for money, noting that it comes with a carbon frame, carbon forks, carbon seat post, carbon integrated handlebars, 50mm carbon wheels, and a WheelTop electronic groupset for about $1,639 delivered. He considers the electronic groupset a standout feature, making the bike feel more expensive than it is, and he would choose it over a mechanical 105 groupset. However, he mentions the bike is not super lightweight at 8.9 kg and the stock saddle was uncomfortable, which he replaced. He also swapped the stock wheels and tires for upgrades. Overall, he is very satisfied with the bike's performance and speed.
