望专业人士发表下对这两款车的见解，从性价比，舒适性，安全性探讨下
LZ那老款atx770和新版atx770-D比较就有点麻烦了，亏旅先把碟刹抛开不说新版atx770-D整体性能要比老款atx770高，主要体现在变速器，前叉和涂装，老款atx770变速器是半ALIVIO（前变是Acera后变是ALIVIO），atx770-D是全ALIVIO，前叉新款比老款有所提升。我建议LZ买2011的ATX770啊，和新版atx770-D配置基本一样，不同的是770D前叉带锁死，770不带锁死，可以买个2011款770再自己配个BB5碟刹这样很划算。而且LZ提到安全，2011 ATX770涂装有红白的，这个颜色很安全，醒目。LZ不选新款770可能是因为新款770前叉坏了不好配，放心，前叉没那么容易坏，，等前叉坏了那车子整体也就基本报废了。但尊重LZ的意愿，如果不在意新款的那些性能提升肯定买老款770，然后自己加个BB5碟刹，要不就直接买新款770D，千万别买老款770D，很鸡肋的一款车子。最后选择就是我的裂空祥建议，新款770自己加配BB5碟刹。舒适性都差不多，不过新款770和770D的车座配的是肆搏WTB PURE V座垫，口碑相当好的一款，很有名，非常不错的一款坐垫，做起来挺舒服。够详细了吗？
770好，我的就是，闪蓝的，770在配置上都优于770d，770d只是多了个碟刹，而且也不是什么好碟刹，除了多了个破碟刹，其他配置都比770低一档，770是性价比很亮毁腔高的一款车，前叉也比较软，也可调余和软硬，很适合城市和小山地，安全性也很牛叉，这点敬衫我就不多说了
