Review from Pinkbike

"The Turnon Bunker has proven itself worthy, with an impressively durable design and consistent performance over a long test period. The 190mm maximum drop isn't enough to compete with the longest options out there, but the longevity, weight, and self-bleeding function all add up to a dropper post that deserves some attention. "

The recessed screw heads make the overall appearance more refined and include a 5-gram weight reduction.

2024 Dancup
因為今年是氣溫相當高的情況，很大的考驗是騎手的體力會下降很快。

對於體力節省，可以利用Bunker dropper post的推力特色，隨著地形變化，當從低點欲改變高點騎姿的時侯，可以藉由該推力幫助起身動作，除了能減少一點體力耗損，對持續踩踏不因起身動作停留也有幫助。

依行程跟氣壓值，壓縮後推力約30～40kg
可以想像是做深蹲時，在最出力的低點位置，幫助減少這些重量。

The new review from Australia Tyres and Soles comes with a long-term evaluation, providing a more detailed description of our unique dual-chamber system.

Indeed, it isn't easy to easily discern the distinction of each brand's dropper, especially those droppers that install the same cartridge.
Even more challenging is verifying its durability.

Through this review, you can understand how our Bunker's fully sealed design can bring numerous advantages to the product.
