As a professional and cost-effective racing endurance bike, whose mission is to maintain high cost-effective and create excellent riding quality on the basis of considering performance. Headset top 1-1/8, down 1-1/2, BSA and 31.6 seatpost, all these three are the best choices for cost-effective.However, the flat top tube and the rhombic down tube are used in the modeling, so as to achieve high rigidity, aslo improve the trampling efficiency and the sensitivity of handlebar override.

Headset top 1-1/8, down 1-1/2, which can ensure the control of riding on the curve calmly and stably. The concave head tube shape makes the head tube high rigidity but less bulky at the same time.
31.6cm seatpost is more convenient for you to buy in the market, and it is also the best consideration to reduce assembly and maintenance costs.
BSA's cost performance options, whose stability and maintenance cost minimization are also obvious.
Hub and Tire Assembling
Hub matching is 142 * 12 100 * 12 . And the option of the largest tire is 700x28c, because the 32C high resistance tire is not an entry-level option to consider.
Freewheel and Crankset Assembling
When your hot blood is boiling, 53—39T won't leave you feeling overwhelmed.
Without considering the wind resistance, we choose the exposed cable, which is a choice for the convenience of maintenance. Of course, in order to optimize the expansion of the horizontal shifting cable, we optimize the shape of the downtube and headtube, and at the same time improve the rigidity of the headtube. Outgoing line of rear derailleur go out from the right side of the droupout.
