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. "

We now have titanium screws specifically for Bunker’s clamps using
The recessed screw heads make the overall appearance more refined and include a 5-gram weight reduction.

It is recommended to apply anti-seize paste (ex: ASC-1)and tighten them using the specified torque.

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。
