桶轴就是上螺丝固定的，要用扳手；快拆用手拆就可以了。桶轴优点就是车轮不会掉，而快拆没锁紧的话轮子可能会晃动甚至掉落。
前轮为例 桶轴是15mm 20mm轴心（dt的12mm迷你桶轴暂且不论）快拆是9mm轴心 桶轴是封闭式固定 快拆是半开口式 桶轴优点是刚性好 高强度骑行桶轴操控稳定性更佳 缺点是重量稍重几十克 拆卸相对普通快拆麻烦一点
快拆优缺点和桶轴相反
近年来桶轴是山地领域发展趋势 大行程车上基本都是15桶甚至20桶了 xc车架后轮也有向142 12开档发展的趋势 有条件尽量选择15mm桶轴 不过注意匹配相应的轮组

还有目前多数桶轴其实是叫快拆桶轴 不需要扳手拆卸。

理论上的就不说了，说说体验上的问题，平时通勤快拆没问题，如果喜欢折腾，比如高速过减速带，下楼梯，等等有强度的操作，快拆感觉会有点问题。我之前就是后轮有些松动。还有异响
