Material:
7075 high-hardness aluminum alloy, after mechanical simulation, the extension kit can withstand 15.8 tons of pressure, but twice the predicted daily riding pressure is only 0.3 tons, so the extension will not break if the original frame piece is broken, and the strength is completely sufficient.
Original wheelbase: 124cm
Extended wheelbase: 133cm
The position of the pedals after the extension is relatively forward, so the steep slopes and riding will be more comfortable, but it will be more difficult to tilt your head and do climbing movements. Although the wheelbase of the climbing bike is the same, the pedals are closer to the rear wheel for easier tilting and action. The disadvantages brought by the lengthened flat fork, when you do a little head-turning action and turn around in place, you need to re-familiarize yourself with the center of gravity and feel, and it will be better if you practice it again for a while. The pedals can be adjusted backwards by one click.
